IOS1_ARATH | developmental stage | Predominantly expressed in tissue with fates controlled by the phytohormone abscisic acid (ABA). In roots, expressed in the radicle emerging from the testa, in the elongation zones of roots, and in root cap border cells undergoing detachment. In hypocotyls, detected only during etiolation in the dark. In cotyledons and leaves, restricted to cells surrounding stomata. In reproductive organs, observed in the style after pollination, in the abscission zones of sepals and petals, in the transmitting tract of developing fruits, and in the abscission zones of mature siliques. Also present in pollen tubes. |
IOS1_ARATH | function | Negatively regulates the abscisic acid (ABA) signaling pathway (PubMed:25274985). Required for full susceptibility to filamentous (hemi)biotrophic oomycetes (e.g. H.arabidopsidis and P.parasitica) and fungal (e.g. E.cruciferarum) pathogens, probably by triggering the repression of ABA-sensitive COLD REGULATED and RESISTANCE TO DESICCATION genes during infection, but independently of immune responses (PubMed:21711359, PubMed:25274985). Involved in BAK1-dependent and BAK1-independent microbe-associated molecular patterns (MAMPs)-triggered immunity (PTI) leading to defense responses, including callose deposition and MAPK cascade activation, toward pathogenic bacteria (e.g. P.syringae). Required for chitin-mediated PTI (PubMed:27317676). |
IOS1_ARATH | similarity | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. |
IOS1_ARATH | tissue specificity | Expressed in roots, cotyledons, leaves, flowers and siliques. |
