Phenomics studies a variety of phenotypic plant traits and is the key to understanding genetic functions and environmental effects on plants. With the rapid development of genomics, many plant phenotyping platforms have been developed to study complex traits related to the growth, yield, and adaptation to biotic or abiotic stress, but the ability to acquire high-throughput phenotypic data has become the bottleneck in the study of plant genomics. In recent years, researchers around the world have conducted extensive experiments and research on high-throughput, image-based phenotyping techniques, including visible light imaging, fluorescence imaging, thermal imaging, spectral imaging, stereo imaging, and tomographic imaging. This paper considers imaging technologies developed in recent years for high-throughput phenotyping, reviews applications of these technologies in detecting and measuring plant morphological, physiological, and pathological traits, and compares their advantages and limitations.

Weeping species are used both as ornamental plants and for breeding dwarf plant types. However, exploration of casual genes controlling weeping traits is rather limited. Here, we identified individuals with contrasting phenotypes from an F1 bi-parental mapping population of Prunus mume which was developed from a cross between the upright cultivar ‘Liuban’ and the weeping cultivar ‘Fentai Chuizhi’. Bulked segregant RNA sequencing was used and five QTLs on Chromosome 7 were identified. The Pm024074(PmUGT72B3) allele, belonging to the UDP-glycosyltransferase superfamily containing the coniferyl-alcohol glucosyltransferase domain, was identified in a genomic region overlapping with a previously identified QTL, and had a synonymous transition of T66(upright) to C (weeping) in the coding sequence and a 470-bp deletion in the promoter region. Pm024074 had exceptionally high expression in buds and stems of weeping P. mume. Weighted correlation network analysis indicates that genes neighboring Pm024074 were significantly associated with plant architecture. In addition, a reliable single nucleotide polymorphism marker was developed based on the variation in the Pm024074 gene, providing precise marker-assisted breeding for weeping traits. This study provides insights into the genetic mechanism governing the weeping trait in P. mume, and indicates potential applications for the manipulation of tree architecture.

水是一种有限而宝贵的资源。新加坡的国家水源有4种补给方式,其中之一是自然降水。雨水径流会收集污染物,并将其富集到排水系统和水库中。在当地雨水径流中发现的主要富营养污染物包括硝酸盐和磷酸盐,这些富营养污染物可能导致富营养化。在有植物存在的情况下,生物滞留系统可以有效去除这些污染物。本文探讨了植物特性对雨水径流中营养性污染物的植物修复作用,并将其应用于生物防护系统中。所研究的植物物种在叶绿素含量、叶片绿色的浓度、生物量的产生以及硝酸盐和磷酸盐去除方面表现出了差异。一般而言,干生物量与硝酸盐和磷酸盐的去除程度相关(r = 0.339~0.501)。本地树种的根、叶和总干生物量显示出与硝酸盐去除程度之间的中等至强相关性(r 分别为0.811、0.657和0.727)。速生植物的叶片干生物量与两种污染物的去除程度也显示出中等至强相关性(r 分别为0.707和0.609)。低生长植株的根系生物量与磷的去除有很强的相关性(r = 0.707),但与硝酸盐去除的相关性较弱(r = 0.557)。这些结果对于选择用于生物滞留系统的植物是有价值的。

既往研究已发现免疫球蛋白 G(immunoglobulin G, IgG)N-糖基化与代谢特征之间存在关联,但它们之间是否存在因果关联尚有待研究。本研究使用孟德尔随机化(Mendelian randomization, MR)研究方法整合全基因组关联研究(genome-wide association studies, GWAS)和数量性状基因座(quantitative trait loci, QTL)数据探究IgG N-糖基化与代谢特征之间的双向因果关联。在正向MR分析中,通过整合IgG N-糖基-QTL遗传变异与GWAS 数据和代谢特征进行分析,分别发现59个包括影响体质指数(body mass index, BMI)的9个IgG N-糖基(glycan peaks, GP)(GP1和GP6等)和影响空腹血糖(fasting plasma glucose, FPG)的 7个IgG N-糖基(GP1和GP5等)以及15个[包括影响BMI 的5个IgG N-糖基(GP2 和 GP11 等)和影响FPG的 4个IgG N-糖基(GP1和GP10等)]由遗传决定的 IgG N-糖基在单样本和两样本MR研究中与代谢特征存在因果关联(全部 P < 0.05)。相应地,对整合代谢特征-QTL-遗传变异与GWAS结果和 IgG N-糖基进行MR分析的结果显示,在单样本和两样本MR研究中,分别发现72个包括影响GP1的1个因果代谢特征[高密度脂蛋白胆固醇(high-density lipoprotein cholesterol, HDL-C)]和影响GP2的5个因果代谢特征[FPG、收缩压(systolic blood pressure, SBP)等]和4个[包括影响GP3的1个因果代谢特征(HDL-C)和影响 GP9 的1个代谢特征(HDL-C)]由遗传决定的代谢特征与 IgG N-糖基之间存在因果关联(全部 P < 0.05)。值得注意的是,在单样本和两样本的MR分析中均发现了遗传决定的高水平的GP11与BMI水平增高存在因果关联[固定效应模型-Beta (SE): 0.106 (0.034) 和 0.010 (0.005)]和高水平的HDL-C与 GP9 水平降低存在因果关联[−0.071 (0.022) 和−0.306 (0.151)],且这一结果在单样本和两样本的 meta汇总分析中得到了进一步验证[固定效应模型-Beta(95%置信区间)分别为:0.0109 (0.0012, 0.0207) 和−0.0759 (−0.1186, −0.0332)]。综上所述,本研究全面的双向MR分析提供了IgG N-糖基化与代谢特征之间双向因果关联的证据,在一定程度上揭示了 IgG N-糖基化与代谢特征之间的生物学机制。
