绒毡层的发育受到众多转录因子的调控 (Liu et al., 2023; Gomez et al., 2023),然而,对于参与这一过程的信号级联通路尚未有明确的解析。 近日,JIPB在线发表了南京农业大学赵晶等人题为“Sporophytic control of tapetal development and pollen fertility by a mitogen-activated protein kinase cascade in rice”...
Here, we investigated the role of OsVQ1 in rice disease resistance and the control of flowering time. The OsVQ1 -knock out (KO) mutants exhibited increased resistance to Xanthomonas oryzae pathovars, accumulated high levels of hydrogen peroxide (H 2 O 2 ), and showed a late flowering ...
Mitogen-activated protein kinase (MAPK) cascades play important roles in diverse developmental and physiological processes of plants, including pathogen-induced defense responses. Although at least 17 rice MAPKs have been identified and more than half of these MAPK genes have been shown to be pathogen...
Molecular characterization of a substantial number of Xoo-resistance genes and related pathways has considerably enhanced our understanding of the rice–Xoo interaction and the mechanism of resistance, while markedly less is known about the rice–Xoc interaction (Zhang and Wang, 2013; Ke et al., ...
Rice false smut caused by Ustilaginoidea virens is emerging as a devastating disease of rice (Oryza sativa) worldwide; however, the molecular mechanisms underlying U. virens virulence and pathogenicity remain largely unknown. Here we demonstrate that the small cysteine-rich secreted protein SCRE6 in...
GRAIN LENGTH AND AWN 1 negatively regulates grain size in rice Grain size is an important factor determining yield in rice. Here, we identified a recessive mutant gene, grain length and awn 1(gla1), which caused a significant increase in grain length and weight, and was associated with long...

RiceMAPKRedox-controlSite-directed mutagenesisIn vitro kinase activityTwo subgroup A rice mitogen-activated protein kinases (MAPKs), OsMPK3 and OsMPK6, have been implicated in multiple stress responses. However, the redox-control of the kinase activity of these proteins remains unknown. Here, ...
Our results elucidate a MAPK activation pathway in rice that is independent of traditional MKK-mediated phosphorylation, highlighting the crucial roles of OsCPK5 and OsCPK13 in directly phosphorylating and activating OsMPK3/6, which are important for rice tolerance to salt stress.Su Shiqi...
