Coronatine orchestrates ABI1‐mediated stomatal opening to facilitate bacterial pathogen infection through importin β protein SAD2 Plant J. (IF 7.2) Pub Date : 2024-04-29 Lu Liu, Yanzhi Liu, Xuehan Ji, Xia Zhao, Jun Liu, Ning Xu
SUMMARYStomatal immunity plays an important role during bacterial pathogen invasion. Abscisic acid (ABA) induces plants to close their stomata and halt pathogen invasion, but many bacterial pathogens secrete phytotoxin coronatine (COR) to antagonize ABA signaling and reopen the stomata to promote infection at early stage of invasion. However, the underlining mechanism is not clear. SAD2 is an importin

Promotion of apoplastic oxidative burst by artificially selected GhCBSX3A enhances Verticillium dahliae resistance in upland cotton Plant J. (IF 7.2) Pub Date : 2024-04-01 Yihao Zhang, Yuan Yuan, Hongfang Xi, Yaning Zhang, Chenxu Gao, Meng Ma, Qian Huang, Fuguang Li, Zhaoen Yang
SUMMARYVerticillium wilt (VW) is a devasting disease affecting various plants, including upland cotton, a crucial fiber crop. Despite its impact, the genetic basis underlying cotton's susceptibility or defense against VW remains unclear. Here, we conducted a genome‐wide association study on VW phenotyping in upland cotton and identified a locus on A13 that is significantly associated with VW resistance

Genome‐wide association identifies a BAHD acyltransferase activity that assembles an ester of glucuronosylglycerol and phenylacetic acid Plant J. (IF 7.2) Pub Date : 2024-04-01 Jeffrey P. Simpson, Colin Y. Kim, Amanpreet Kaur, Jing‐Ke Weng, Brian Dilkes, Clint Chapple
SUMMARYGenome‐wide association studies (GWAS) are an effective approach to identify new specialized metabolites and the genes involved in their biosynthesis and regulation. In this study, GWAS of Arabidopsis thaliana soluble leaf and stem metabolites identified alleles of an uncharacterized BAHD‐family acyltransferase (AT5G57840) associated with natural variation in three structurally related metabolites

Critical role of cyclic electron transport around photosystem I in the maintenance of photosystem I activity Plant J. (IF 7.2) Pub Date : 2024-04-01 Ryouhei Kobayashi, Hiroshi Yamamoto, Kota Ishibashi, Toshiharu Shikanai
SUMMARYIn angiosperms, cyclic electron transport around photosystem I (PSI) is mediated by two pathways that depend on the PROTON GRADIENT REGULATION 5 (PGR5) protein and the chloroplast NADH dehydrogenase‐like (NDH) complex, respectively. In the Arabidopsis double mutants defective in both pathways, plant growth and photosynthesis are impaired. The pgr5‐1 mutant used in the original study is a missense
