Africa in facing numerous challenges in the 21st century in feeding its rapidly increasing population. Land resources have become limited due to urbanization and industrialization. The existing agricultural land has been degraded and soil fertility has declined due to unsustainable farming practices. Despite of progress made in the past several decades, hunger and malnutrition in Africa still hinder health, human development and economic growth, which will become even worse in the future if proper measures are not taken. Sustainable intensification is the only solution to tackling both environmental sustainability including climate change and malnutrition, i.e., to produce more foods in terms of nutrients human body needs with less natural resources and carbon emissions. To achieve this vision, innovations in technologies, policies and institutions are essential. The Chinese experience in Agricultural Green Development (AGD) can be shared with Africans when the region is pursuing its sustainable intensification strategy.

Childhood obesity and obesity-related metabolic complications are induced by a high-fat postnatal diet. The lack of a suitable animal model, however, remains a considerable challenge in obesity studies. In the current study, we provided high-fat diet (HFD) to dams during lactation and to pups after weaning. We also developed a novel model of C57BL/6J mouse pups with HFD-induced postnatal obesity. Results showed that feeding with HFD induces fat deposition and obesity in pups. Furthermore, HFD more potently increased the body weight (BW) of male than female pups. HFD-fed female pups were obese, underwent precocious puberty, and showed increased kisspeptin expression in the hypothalamus. However, parental obesity and precocious puberty exerted no synergistic effects on the HFD-induced postnatal weight gain and puberty onset of the pups. Interestingly, some HFD-fed litters with normal BW also exhibited precocious puberty. This finding suggested that diet composition but not BW triggers puberty onset. Our model suggests good construction validity of obesity and precocious puberty. Furthermore, our model can also be used to explore the mutual interactions between diet–induced postnatal childhood obesity and puberty.

HEMIPTERAN-TRANSMITTED PLANT VIRUSES: RESEARCH PROGRESS AND CONTROL STRATEGIES
《农业科学与工程前沿(英文)》 2022年 第9卷 第1期 页码 98-109 doi: 10.15302/J-FASE-2021389
About 80% of plant viruses are transmitted by specific insect vectors, especially hemipterans with piercing-sucking mouthparts. Many virus-transmitting insects are also important crop pests that cause considerable losses in crop production. This review summarizes the latest research findings on the interactions between plant viruses and insect vectors and analyzes the key factors affecting insect transmission of plant viruses from the perspectives of insect immunity, insect feeding, and insect symbiotic microorganisms. Additionally, by referring to the latest applications for blocking the transmission of animal viruses, potential control strategies to prevent the transmission of insect-vectored plant viruses using RNAi technology, gene editing technology, and CRISPR/Cas9+ gene-driven technology are discussed.

大菱鲆神经肽Y基因克隆及其在工厂化养殖饥饿-投喂策略中的表达特征分析

本文通过逆转录聚合酶链式反应(RT-PCR)和末端快速扩增技术(RACE)克隆了大菱鲆神经肽Y(NPY)基因全长为729 bp 的互补脱氧核糖核酸(cDNA)序列,其中5′非翻译区(5′-UTR)为70 bp,3′非翻译区(3′-UTR)为359 bp,开放阅读框(ORF)为300 bp。ORF编码含有99 个氨基酸的蛋白质多肽,N端28 个氨基酸为信号肽,信号肽后是由36 个氨基酸组成的NPY成熟肽。针对大菱鲆NPY蛋白质与其他物种的同源性进行比较,结果显示大菱鲆NPY与其他物种的同源性在53.9 %~98 %,特别是与同属于鲆鲽鱼类的牙鲆和美洲拟鲽的同源性高达97 %~98 %,表现出很高的保守性。采用实时定量PCR对大菱鲆NPY基因的表达特征进行分析,结果表明,大菱鲆NPY基因在神经组织和外围组织中都有表达,其中在下丘脑中的表达量最高。饥饿实验中,随着饥饿的进行,NPY的表达量显著变化(P<0.05),呈现先升高再降低,再显著升高并维持一段高水平表达后,再次下降的趋势,饥饿后再投喂会使NPY的表达量升高,并且饥饿时间越长,再投喂后NPY的表达水平越高,但是再投喂2 h 后表达量还会再次下降至相似的水平,这都预示着NPY是一种摄食刺激因子,并且是一种短期的调控机制。

In this work, nickel nanopore arrays with a highly-oriented nanoporous structure inherited from porous alumina membranes were used as nanostructured current collectors for constructing ultrahigh rate solid-state supercapacitors. A thin layer of poly(3,4-ethylenedioxythiophene) (PEDOT) as electroactive materials was conformally coated onto nickel nanopores to form heterostructured electrodes. The as-prepared electrodes have a large specific surface area to ensure a high capacity, and the highly-oriented nanoporous structure of nickel nanopores reduces the ion transport resistance, allowing the ions in the solid-state electrolytes to quickly access the PEDOT surface during the fast charge-discharge process. As a result, the assembled solid-state supercapacitor in a symmetric configuration exhibits an ideal capacitive behavior and a superior rate capability even at an ultrahigh scan rate of 50 V·s−1.
