Photosynthesis and related metabolic mechanism of promoted rice (Oryza sativa

Yingdan Zhang, Na Liu, Wei Wang, Jianteng Sun, Lizhong Zhu

《环境科学与工程前沿（英文）》 2020年 第14卷 第6期 doi: 10.1007/s11783-020-1282-5

摘要： Abstract • The rice growth was promoted by nano-TiO2 of 0.1–100 mg/L. • Nano-TiO2 enhanced the energy storage in photosynthesis. • Nano-TiO2 reduced energy consumption in carbohydrate metabolism and TCA cycle. Titanium dioxide nanoparticle (nano-TiO2), as an excellent UV absorbent and photo-catalyst, has been widely applied in modern industry, thus inevitably discharged into environment. We proposed that nano-TiO2 in soil can promote crop yield through photosynthetic and metabolic disturbance, therefore, we investigated the effects of nano-TiO2 exposure on related physiologic-biochemical properties of rice (Oryza sativa L.). Results showed that rice biomass was increased >30% at every applied dosage (0.1–100 mg/L) of nano-TiO2. The actual photosynthetic rate (Y(II)) significantly increased by 10.0% and 17.2% in the treatments of 10 and 100 mg/L respectively, indicating an increased energy production from photosynthesis. Besides, non-photochemical quenching (Y(NPQ)) significantly decreased by 19.8%–26.0% of the control in all treatments respectively, representing a decline in heat dissipation. Detailed metabolism fingerprinting further revealed that a fortified transformation of monosaccharides (D-fructose, D-galactose, and D-talose) to disaccharides (D-cellobiose, and D-lactose) was accompanied with a weakened citric acid cycle, confirming the decrease of energy consumption in metabolism. All these results elucidated that nano-TiO2 promoted rice growth through the upregulation of energy storage in photosynthesis and the downregulation of energy consumption in metabolism. This study provides a mechanistic understanding of the stress-response hormesis of rice after exposure to nano-TiO2, and provides worthy information on the potential application and risk of nanomaterials in agricultural production.

Visible light responsive photocatalysts developed by substitution with metal cations aiming at artificial photosynthesis

《能源前沿（英文）》 2021年 第15卷 第3期   页码 568-576 doi: 10.1007/s11708-021-0774-8

摘要： To solve resource, energy, and environmental issues, development of sustainable clean energy system is strongly required. In recent years, hydrogen has been paid much attention to as a clean energy. Solar hydrogen production by water splitting using a photocatalyst as artificial photosynthesis is a promising method to solve these issues. Efficient utilization of visible light comprised of solar light is essential for practical use. Three strategies, i.e., doping, control of valence band, and formation of solid solution are often utilized as the useful methods to develop visible light responsive photocatalysts. This mini-review introduces the recent work on visible-light-driven photocatalysts developed by substitution with metal cations of those strategies.

摘要： A full-length cDNA library from leaf and root tissues of cassava ( ) Arg7 and one accession of its wild ancestor W14 ( ssp. ) has been constructed. The library is comprised of four sub-libraries, containing 32640 recombinant clones, 6028 cDNA clones from their 5′ ends, and 128 clones from the 3′ ends were sequenced. In total, 5013 high-quality expressed sequence tags (ESTs) and 1259 unigenes were obtained. Of these, 746 unigenes were identified by their sequence homologies to ESTs from model plants, and 323 unigenes were mapped onto 114 different KEGG pathways. From these, 24 differentially expressed genes involved in starch metabolism and photosynthesis were identified and five of them were selected to compare their expression level between Arg7 and W14. Notably, Arg7 has a higher net photosynthesis rate in leaves, higher ribulose-1,5-bisphosphate carboxy-lase oxygenase activities in leaves, and higher AGPase activity in roots. This resource is the first EST collection from wild cassava and should be of value for gene discovery, genome annotation and studies of evolution.

Impact of photosynthesis and transpiration on nitrogen removal in constructed wetlands

LUO Weiguo, WANG Shihe, HUANG Juan, YAN Lu, HUANG Jun

《环境科学与工程前沿（英文）》 2007年 第1卷 第3期   页码 316-319 doi: 10.1007/s11783-007-0053-x

摘要： To determine the impact of photosynthesis and transpiration on nitrogen removal in wetlands, an artificial wetland planted with reeds was constructed to treat highly concentrated domestic wastewater. Under different meteorological and hydraulic conditions, the daily changes of photosynthesis and transpiration of reeds, as well as nitrogen removal efficiency were measured. It was found that net photosynthesis rate per unit leaf area was maintained on a high level (average 19.0 yDol CO/(m · s) ) from 10:00 to 14:00 in July 2004 and reached a peak of 21.1 μmol CO/(m · s) when Photon Flux Density was high during the day. Meanwhile, TN and NH-N removal efficiency rose to 79.6% and 89.6%, respectively–the maximum values observed in the test. Correlation coefficient analysis demonstrated a positive correlation among photon flux density, net photosynthetic rate, transpiration rate, and TN and NH-N removal efficiency. In contrast, there was a negative correlation between stomatal conductance and TN and NH-N removal efficiency. Results suggest that the photosynthesis and transpiration of wetland plants have a great impact on nitrogen removal efficiency of wetlands, which can be enhanced by an increase in the photosynthesis and transpiration rate. In addition, the efficiency of water usage by reeds and nitrogen removal efficiency could be affected by the water level in wetlands; a higher level boosts nitrogen removal efficiency.

《农业科学与工程前沿（英文）》 2016年 第3卷 第4期   页码 368-374 doi: 10.15302/J-FASE-2016120

摘要： A greenhouse pot experiment was conducted to study the effects of nitrogen fertilization on seedlings grown with 0, 50, 100, 150, 200, 300, 400 and 600 mg N per seedling according to exponential functions. Seedling height, root collar diameter, leaf area and total biomass increased with increasing fertilization from 0 to 200 mg N per seedling and decreased with further increase in fertilization from 300 to 600 mg N per seedling. The net photosynthetic rate, stomatal conductance, intercellular CO concentration and transpiration rate of seedlings showed a unimodal parabolic trend, with peak values of 7.29 mmol·m ·s , 0.071 mol·m ·s , 220 mmol·mol and 1.34 mmol·m ·s , respectively, when the rate of fertilization was 200 mg N per seedling. Photosynthetic gas exchange parameters were significantly different among nitrogen treatments. Based on the critical values of leaf N and P concentration and N/P ratio, the optimum amount of nitrogen of seedlings was 200–400 mg per seedling for leaf N and P concentration, and 100–400 mg per seedling for N/P ratio. It was concluded that 200–400 mg N per seedling was the most suitable nitrogen range for seedlings.

《农业科学与工程前沿（英文）》 2014年 第1卷 第1期   页码 16-20 doi: 10.15302/J-FASE-2014011

摘要： Model organisms such as Arabidopsis ( ) and rice ( ) have proven essential for efficient scientific discovery and development of new methods. With the diversity of plant lineages, some important processes such as C photosynthesis are not found in either Arabidopsis or rice, so new model species are needed. Due to their small diploid genomes, short life cycles, self-pollination, small adult statures and prolific seed production, domesticated foxtail millet ( ) and its wild ancestor, green foxtail ( ), have recently been proposed as novel model species for functional genomics of the Panicoideae, especially for study of C photosynthesis. This review outlines the development of these species as model organisms, and discusses current challenges and future potential of a Setaria model.

Ga(X)N/Si nanoarchitecture: An emerging semiconductor platform for sunlight-powered water splitting toward hydrogen

《能源前沿（英文）》 doi: 10.1007/s11708-023-0881-9

摘要： Sunlight-powered water splitting presents a promising strategy for converting intermittent and virtually unlimited solar energy into energy-dense and storable green hydrogen. Since the pioneering discovery by Honda and Fujishima, considerable efforts have been made in this research area. Among various materials developed, Ga(X)N/Si (X = In, Ge, Mg, etc.) nanoarchitecture has emerged as a disruptive semiconductor platform to split water toward hydrogen by sunlight. This paper introduces the characteristics, properties, and growth/synthesis/fabrication methods of Ga(X)N/Si nanoarchitecture, primarily focusing on explaining the suitability as an ideal platform for sunlight-powered water splitting toward green hydrogen fuel. In addition, it exclusively summarizes the recent progress and development of Ga(X)N/Si nanoarchitecture for photocatalytic and photoelectrochemical water splitting. Moreover, it describes the challenges and prospects of artificial photosynthesis integrated device and system using Ga(X)N/Si nanoarchitectures for solar water splitting toward hydrogen.

PROTECTIVE ROLES OF D1 PROTEIN TURNOVER AND THE XANTHOPHYLL CYCLE IN TOMATO (SOLANUM LYCOPERSICUM) UNDER SUB-HIGH TEMPERATURE AND HIGH LIGHT STRESS

《农业科学与工程前沿（英文）》 2021年 第8卷 第2期

摘要：

D1 protein turnover and the xanthophyll cycle (XC) are important photoprotective mechanisms in plants that operate under adverse conditions. Here, streptomycin sulfate (SM) and dithiothreitol (DTT) were used in tomato plants as inhibitors of D1 protein turnover and XC to elucidate their photoprotective impacts under sub-high temperature and high light conditions (HH, 35°C, 1000 µmol·m-2·s-1). SM and DTT treatments significantly reduced the net photosynthetic rate, apparent quantum efficiency, maximum photochemical efficiency, and potential activity of photosystem II, leading to photoinhibition and a decline in plant biomass under HH. The increase in reactive oxygen species levels resulted in thylakoid membrane lipid peroxidation. In addition, there were increased non-photochemical quenching and decreased chlorophyll pigments in SM and DTT application, causing an inhibition of D1 protein production at both transcriptional and translational levels. Overall, inhibition of D1 turnover caused greater photoinhibition than XC inhibition. Additionally, the recovery levels of most photosynthesis indicators in DTT-treated plants were higher than in SM-treated plants. These findings support the view that D1 turnover has a more important role than XC in photoprotection in tomato under HH conditions.

摘要： Fungal endophytes of some cultivated grasses can increase plant performance and competitive abilities, especially under stress. Far less is known about the influence of infections in wild populations of wild grasses. In this study, plants of three ecotypes (WLS, QY and WTS) either infected with endophyte (E+) or uninfected (E–) were grown in the field. The activities of the antioxidant enzymes ascorbate peroxidase, catalase, peroxidase and superoxide dismutase, and concentrations of H O and malondialdehyde were examined in the leaves of E+ and E– plants. We also determined photosynthesis parameters, leaf blade and sheath carbohydrate concentration and plant growth parameters of both E+ and E– plants. E+ plants from the WLS and QY populations had significantly higher antioxidant enzyme activities and photosynthetic capability ( <0.05), superior growth characteristics including more abundant carbohydrate concentration than E– plants. In contrast, in plants from the WTS population, the endophyte had no significant effect on reactive oxygen species scavenging capability and growth performance ( >0.05), and even displayed some negative effects on plant photosynthetic capability. Thus, endophyte infection significantly affected antioxidant enzyme activities ( <0.05), photosynthesis and growth capability, although, the effects varied with plant ecotypes.

摘要： Physiological responses to low temperature were analyzed in a chilling-tolerant centipedegrass ( ) accession, Shao Guan (SG), in comparison to the commercial cultivar, Common. Lower levels of ion leakage and higher chlorophyll (Chl) concentration were observed in SG than in Common during chilling stress. The maximum photochemical efficiency, the actual photosystem II (PSII) efficiency, photochemical quenching efficiency, and net photosynthetic rate were decreased during chilling stress in both genotypes, with higher levels of these parameters shown by SG than Common. In addition, higher activities of superoxide dismutase (SOD), catalase (CAT), ascorbate-peroxidase (APX) and glutathione reductase (GR), and higher concentrations of ascorbic acid (AsA) and glutathione (GSH) were observed in SG than in Common. Moreover, higher concentrations of putrescine (Put), spermidine (Spd), and spermine (Spm) were observed in SG than in Common. Correlation analysis indicated that SOD, CAT, APX and GR activities, and AsA and GSH concentrations showed high correlation to Put, while APX, GR, and AsA concentrations were correlated to Spd. Exogenous Put or Spd increased antioxidant enzyme activities and chilling tolerance. The results suggested that polyamine-regulated antioxidants are important for chilling tolerance in centipedegrass and protect plants against chilling induced oxidative damage.

摘要： Cassava is a staple food, feed and bioenergy crop important to the world especially in the tropics. Domesticated cassava is characterized by powerful carbohydrate accumulation but its wild progenitor is not. Here, we investigated the transcriptional differences of eight cDNA libraries derived from developing leaf, stem and storage root of cassava cv. Arg7 and an ancestor line, W14, using next generation sequencing system. A total of 41302 assembled transcripts were obtained and from these, 25961 transcripts with FPKM≥3 in at least one library were named the expressed genes. A total of 2117, 1963 and 3584 transcripts were found to be differentially expressed in leaf, stem and storage root (150 d after planting), respectively, between Arg7 and W14 and ascribed to 103, 93 and 119 important pathways in leaf, stem and storage root, respectively. The highlight of this work is that the genes involved in light response, such as those for photosystem I (PSA) and photosystem II (PSB), other genes involved in light harvesting, and some of the genes in the Calvin cycle of carbon fixation were specially upregulated in leaf. Genes for transport and also for key rate-limiting enzymes (PFK, PGK and PK, GAPDH) coupling ATP consumption in glycolysis pathway were predominantly expressed in stem, and genes for sucrose degradation (INVs), amylose synthesis (GBSS) and hydrolysis (RCP1, AMYs), the three key steps of starch metabolism, and transport associated with energy translocation (ABC, AVPs and ATPase) and their upstream transcription factors had enhanced expression in storage root in domesticated cassava. Co-expression networks among the pathways in each organs revealed the relationship of the genes involved, and uncovered some of the important hub genes and transcription factors targeting genes for photosynthesis, transportation and starch biosynthesis.

摘要：

光合微生物是生产环境友好的目标产品的重要生物资源，光生物反应器是实现这些过程的重要工具。目前，用于光催化的光生物反应器的设计具有挑战性，大多数光反应器仍然采用半经验的方法进行设计和放大。即使对于高效的光生物反应器，由于缺乏对光的传播、流体动力学、传质、细胞生长之间耦合作用的深刻了解，依靠半经验方法设计的反应器具有投资和运行成本高、使用寿命短的缺点，因此迄今为止尚没有一款合适的光生物反应器可用于光合微生物的大规模培养。首先，本文概述了影响光生物反应器性能的关键参数包括光、混合、传质、温度、pH 值、投资和运行成本等，强调了在商业化培养中光生物反应器的寿命、清洁成本和温度控制的重要性。然后，推荐了四种( 即管式光生物反应器、塑料袋式光生物反应器、柱状气升环流式光生物反应器和平板气升环流式光反应器) 可进行光合微生物大规模培养的光生物反应器。最后，阐述了采用计算流体力学这一有力工具进行光生物反应器建模从而实现光生物反应器的理性设计，并分析了当今数学建模的难点，展示了基于机理模型设计光生物反应器的发展前景。

《中国工程科学》 2012年 第14卷 第3期   页码 70-75

摘要：

采用盆栽试验，以玉米品种苏玉19为试材，在每次复水第7天同时测定不同处理植株的生物量、根冠比、叶绿素荧光、气体交换以及光谱特征等指标。结果表明，持续干旱处理抑制植株生长，增加根冠比，并通过气孔限制和非气孔限制因素抑制光合作用。持续干旱处理幼苗的mSR705、chlNDI和REP均显著小于对照，但对SIPI的影响不显著。多变低水环境下玉米幼苗生长明显受到抑制，但根冠比、叶绿素荧光、气体交换以及光谱特征等指标与正常供水没有差异。可见，生物量分配、光合作用和光谱特征的维持可能是玉米适应多变低水环境的重要生理机制。
