Kalancho? PPC1 is Essential for Crassulacean Acid Metabolism and the Regulation of Core Circadian Clock and Guard Cell Signaling Genes
Crassulacean acid metabolism (CAM) plants oxaloacetate phosphoenolpyruvate carboxylase circadian clock
2024/1/22
Unlike C3 plants, Crassulacean acid metabolism (CAM) plants fix CO2 in the dark using phosphoenolpyruvate carboxylase (PPC; EC 4.1.1.31). PPC combines PEP with CO2 (as HCO3-), forming oxaloacetate tha...
Harmonizing Forest Conservation Policies with Essential Biodiversity Variables Incorporating Remote Sensing and Environmental DNA Technologies
environmental DNA essential biodiversity variables forest conservation policies indicators remote sensing biodiversity products
2023/12/8
It remains difficult to compare the state of conservation of forests of different nations. Essential Biodiversity Variables (EBVs) are a set of variables designed as a framework for harmonizing biodiv...
A team of scientists at the Whitehead Institute for Biomedical Research and the Broad Institute of MIT and Harvard has systematically evaluated the functions of over 5,000 essential human genes using ...

GhGPAT12/25 Are Essential for the Formation of Anther Cuticle and Pollen Exine in Cotton (Gossypium hirsutum L.)
GhGPAT12 GhGPAT25 陆地棉 旁系同源基因
2024/4/16
GhGPAT12和GhGPAT25为一对位于陆地棉A12/D12染色体上编码甘油-3-磷酸酰基转移酶（GPAT）的旁系同源基因。GhGPAT12/25在发育早期的花药中特异表达，其转录本主要富集于绒毡层和花粉外壁。真核表达实验表明GhGPAT12/25具有sn-2酰基转移酶活性。CRISPR/Cas9介导的基因敲除实验发现GhGPAT12和GhGPAT25存在功能冗余，两基因的同时敲除导致彻底的雄...
