WEBJun 20, 2014 · Histochemical localization of ProOsJAR1:GUS in florets. Floret and stamen at 1 week before floret opening (a), the stage of 2–4 days before anther dehiscence (b), the early stage of anther dehiscence (c), the middle stage of anther dehiscence (d) and the end of anther dehiscence (e).
Natural variation in OsMYB8 confers diurnal floret opening time ...
WEBMar 13, 2024 · OsMYB8 induces the transcription of JA-Ile synthetase OsJAR1, thereby regulating the expression of genes related to cell osmolality and cell wall remodeling in lodicules to promote floret opening.
WEBwe identify OsMYB8 as a key regulator of rice DFOT. OsMYB8 induces the transcription of JA-Ile synthetase OsJAR1, thereby regulating the expression of genes related to cell osmolality and cell ...
WEBTrp and Val and both osjar1 alleles had substantial reduc-tion in content of JA-Ile, JA-Leu and JA-Val in florets. We conclude that OsJAR1 is a JA-amino acid synthetase that is required for optimal flower opening and closing and anther dehiscence in rice.

WEBOsJAR1 and OsJAR2 are jasmonyl-L-isoleucine synthases involved in wound- and pathogen-induced jasmonic acid signalling, 2011, Biochem Biophys Res Commun. The auxin-responsive GH3 gene family in rice Oryza sativa, 2006, Funct Integr Genomics.
OsJAR1 Contributes Mainly to Biosynthesis of the Stress …
WEBJul 23, 2013 · Here we found that OsJAR1 contributes mainly to stress-induced JA-Ile production by the use of an osjar1 Tos17 mutant. The osjar1 mutant was impaired in JA-induced expression of JA-responsive genes and phytoalexin production, and these defects were restored genetically.
OsJAR1 and OsJAR2 are jasmonyl- l -isoleucine synthases involved …
WEBJun 17, 2011 · The correlation of OsJAR1 expression and JA-Ile accumulation suggests that OsJAR1 is involved in JA-Ile synthesis during blast infection. In summary, we have demonstrated that two functionally active JA-Ile synthases are present in rice.
