2023/11/30
Although clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas)-mediated gene editing has revolutionized biology and plant breeding, large-scale, heritable ...
γ-Aminobutyric acid plays a key role in plant acclimation to a combination of high light and heat stress
c-Aminobutyric acid high light heat stress Arabidopsis thaliana abiotic stresses metabolic response GABA
2023/11/30
Plants are frequently subjected to different combinations of abiotic stresses, such as high light (HL) intensity, and elevated temperatures. These environmental conditions pose a threat to agriculture...
The key clock component ZEITLUPE (ZTL) negatively regulates ABA signaling by degradation of CHLH in Arabidopsis
ABA circadian clock ZTL CHLH Arabidopsis signal transduction
2023/11/16
Ubiquitination-mediated protein degradation plays important roles in ABA signal transduction and delivering responses to chloroplast stress signals in plants, but additional E3 ligases of protein ubiq...
针对痕量核素测量时，特征峰容易部分或全部被背景掩盖，提出多重Sallen-Key（MultipleSallen-Key，MSK）谱线处理技术，实现在高背景低含量X射线荧光光谱（X-RayFluorescence，XRF）分析中的应用。对MSK与多次高斯平滑的对比分析表明，在相同平滑效果下，MSK平滑次数更少，代码执行效率更高。对镉大米标准样的XRF实测谱线，做MSK平滑处理后，可以提高工作曲线的线...
Identification of candidate genes for key fibre-related QTLs and derivation of favourable alleles in Gossypium hirsutum recombinant inbred lines with G. barbadense introgressions
