2023年10月7日，Nature plants在线发表了南京农业大学李姗教授团队题为“Improving rice nitrogen-use efficiency by modulating a novel monouniquitination machinery for optimal root plasticity response to nitrogen”的研究论文。该团队在水稻中鉴定到一...
实现重要农作物精准基因组编辑对加快农作物遗传改良进程具有重要意义。引导编辑技术（Prime editing）是一种基于CRISPR/Cas系统的全新精确基因组编辑技术。2020年，包括北京市农林科学院在内的多家实验室实现了植物引导编辑技术的初步突破，但植物基因组中很多位点编辑效率依旧很低，亟需突破技术瓶颈，实现编辑效率显著提升。
系统鉴定和分析了棉花SUN家族蛋白，通过病毒诱导的敲除和CRISPR/cas9介导的GbSUN5敲除，发现尽管花粉活力仍然正常，但是其败育率较高。本研究结果表明：SUN3和SUN5在生物学功能上存在差异，在生殖发育中发挥重要作用。

Enhanced tolerance to low-K+ stress in tobacco plants, that ectopically express the CBL-interacting protein kinase CIPK23 gene
low-K+ tolerance potassium tobacco
2016/7/6
Tobacco (Nicotiana tabacum) has a relatively high requirement for potassium (K+). However, the molecular basis of tolerance to low-K+ stresses in tobacco still remains unknown. Here, we report the rol...
Computational Mining and Survey of Simple Sequence Repeats (SSRs) in Expressed Sequence Tags (ESTs) of Dicotyledonous Plants

When the human genome was first sequenced, experts predicted they would find about 100,000 genes. The actual number has turned out to be closer to 20,000, just a few thousand more than fruit flies hav...
Rapid Identification of Transgenic Cotton (Gossypium hirsutum L.) Plants by Loop-mediated Isothermal Amplification
Bt chitinase CryIA(b) detection loop-mediated isothermal amplification transgenic cotton
2014/2/25
In an attempt to speed up the process of screening of transgenic cotton (G. hirsutum L.) plants, a visual and rapid loop-mediated isothermal amplification (LAMP) assay was adopted. Genomic DNA was ext...
