Journal ArticleDOI
JAZ repressor proteins are targets of the SCF COI1 complex during jasmonate signalling
Bryan Thines,Leron Katsir,Maeli Melotto,Yajie Niu,Ajin Mandaokar,Guanghui Liu,Kinya Nomura,Sheng Yang He,Gregg A. Howe,John Browse +9 more
TL;DR: The results suggest a model in which jasmonate ligands promote the binding of the SCFCOI1 ubiquitin ligase to and subsequent degradation of the JAZ1 repressor protein, and implicate theSCFCOi1–JAZ1 protein complex as a site of perception of the plant hormone JA–Ile.
Journal ArticleDOI
Discovery of nitrate–CPK–NLP signalling in central nutrient–growth networks
Kun-Hsiang Liu,Kun-Hsiang Liu,Yajie Niu,Mineko Konishi,Yue Wu,Hao Du,Hoo Sun Chung,Lei Li,Marie Boudsocq,Marie Boudsocq,Matthew McCormack,Shugo Maekawa,Tetsuya Ishida,Chao Zhang,Kevan M. Shokat,Shuichi Yanagisawa,Jen Sheen +16 more
TL;DR: This work reports unique Ca2+ signalling triggered by nitrate with live imaging of an ultrasensitive biosensor in Arabidopsis leaves and roots, which impair nitrate-stimulated system-wide shoot growth and root establishment.
Journal ArticleDOI
A critical role of two positively charged amino acids in the Jas motif of Arabidopsis JAZ proteins in mediating coronatine- and jasmonoyl isoleucine-dependent interactions with the COI1 F-box protein.
Maeli Melotto,Christy Mecey,Yajie Niu,Hoo Sun Chung,Leron Katsir,Jian Yao,Weiqing Zeng,Bryan Thines,Paul E. Staswick,John Browse,Gregg A. Howe,Sheng Yang He +11 more
TL;DR: It is shown that coronatine, but not its two biosynthetic precursors, also promotes interaction between Arabidopsis COI1 and multiple JAZ proteins, and the critical role of positively charged amino acids in the Jas domain in mediating the JA-Ile/coronatine-dependent JAZ interaction with COI 1 is illustrated.
Journal ArticleDOI
Characterization of JAZ-interacting bHLH transcription factors that regulate jasmonate responses in Arabidopsis
TL;DR: Quantitative real-time RT-PCR expression analysis of nine JA-responsive genes revealed that eight of them were induced in MYC3 and MYC4 overexpression plants, except for a pathogen-responsive gene, PDF1.2.1.
Journal ArticleDOI
Bifurcation of Arabidopsis NLR Immune Signaling via Ca2+-Dependent Protein Kinases
Xiquan Gao,Xin Chen,Wenwei Lin,Sixue Chen,Dongping Lu,Yajie Niu,Lei Li,Cheng Cheng,Matthew McCormack,Jenq-Yunn Sheen,Libo Shan,Ping He +11 more
TL;DR: Functional genomic and biochemical genetic screens identified six closely related Arabidopsis Ca2+-dependent protein kinases (CPKs) in mediating bifurcate immune responses activated by NLR proteins, RPS2 and RPM1, and delineate b ifurcation of complex signaling mechanisms downstream of NLR immune sensors mediated by the myriad action of CPKs with distinct substrate specificity and subcellular dynamics.
