Our results suggest that IBR5 is a phosphatase that modulates phytohormone signal transduction and support a link between auxin and abscisic acid signaling pathways. Auxin is an important plant hormone that plays significant roles in plant growth and development.

2015年10月9日 · Here we report the identification of a suppressor of chs3, ibr5-7 (indole-3-butyric acid response 5), which largely suppresses chilling-activated defense responses. IBR5 encodes a putative dual-specificity protein phosphatase. The accumulation of CHS3 protein at chilling temperatures is inhibited by the IBR5 mutation.

2008年4月18日 · In Arabidopsis, INDOLE-3-BUTYRIC ACID RESPONSE5 (IBR5), a putative dual-specificity protein phosphatase, is a positive regulator of auxin response. Mutations in IBR5 result in decreased plant height, defective vascular development, increased leaf serration, fewer lateral roots, and resistance to the phytohormones auxin and abscisic acid.

2015年10月9日 · IBR5 encodes a putative dual-specificity protein phosphatase. The accumulation of CHS3 protein at chilling temperatures is inhibited by the IBR5 mutation. Moreover, chs3-conferred defense phenotypes were synergistically suppressed by mutations in HSP90 and IBR5.

IBR5 Encodes a Putative Dual-Specificity Phosphatase. We identified the IBR5 gene using map-based positional cloning (see Methods). ibr5-1 was mapped to the top of chromosome 2, between the markers AIR3 and F5G3 (Zolman et al., 2000). We refined the ibr5-1 position to a 41-kb region containing most of BAC T1O3 and one end of BAC F7D11 . We then ...

2014年8月21日 · The INDOLE-3-BUTYRIC ACID RESPONSE5 (IBR5) gene encodes a dual specificity phosphatase that regulates plant auxin responses. IBR5 has been predicted to generate two transcripts through alternative splicing, but alternative splicing of IBR5 has not been confirmed experimentally.

2023年10月15日 · Title: The IBR5 phosphatase promotes Arabidopsis auxin responses through a novel mechanism distinct from TIR1-mediated repressor degradation. IBR5 is an apparent MAP kinase phosphatase. ibr5 mutants display reduced responses to auxin and abscisic acid (ABA).
