2023年8月13日 · We report here that the systemic acquired resistance (SAR) inducer N-hydroxypipecolic acid (NHP) primes Arabidopsis thaliana plants for strongly enhanced metabolic and transcriptional responses to treatment by flg22, an elicitor-active peptide fragment of flagellin.

定义： PSM （Propensity Score Matching，PSM）通过计算每个个体接受某种处理（如治疗、政策干预等）的概率，即 倾向得分 ，然后根据这个概率将实验组和对照组的个体进行匹配，使得两组在关键变量上具有可比性，再估计两者的区别。

2023年10月27日 · NA treatment restored basal resistance to Psm (the resistance activated by Psm on the wild-type plants) in fin4-3, whereas only NAD + treatment induced resistance to Psm in wild type and...

PSM在 stata 的实现过程。 首先，如果自变量是连续变量，需要转换为二元离散变量，比如自变量是企业R&D投入，你需要找到一个临界值，把R&D投入分为高R&D投入组和低R&D投入组，临界值包括：平均数，上下三分位数，及其他分位数等，没有明确规定。

2024年9月12日 · Previous reports showed that the virulent Pseudomonas syringae pv. maculicola (Psm) ES4326 strain induced a significant NHP increase in uninoculated distal leaves 24 hours postinoculation (hpi), preceding SA induction at 48 hpi (15, 20, 21, 24), whereas when the avirulent Psm ES4326 strain expressing the effector AvrRpt2 was used, a slight SA in...

2018年4月5日 · In the present study, we identify the biochemical function of FMO1 as pipecolate N-hydroxylase, catalyzing the biosynthesis of the as yet undescribed N-hydroxylated amino acid N-hydroxypipecolic acid (NHP) from Pip. Upon pathogen inoculation, NHP accumulates systemically in the Arabidopsis foliage and induces SAR to P. syringae and Hpa infection.
