Comments
Comment typeDescription
Developmental StageLow expression after germination followed by an abrupt level increase in 10-days old seedlings. Accumulates in senescent leaves. {ECO:0000269|PubMed:19781011}.
Disruption PhenotypeLate flowering and defective in UV-C light acceleration of flowering. Strong reduction of FLOWERING LOCUS T (FT) expression. Hypersensitivity to abscisic acid (ABA) and alterations in polar lipid contents and their corresponding fatty acids; reduced levels of phosphatidylinositol (PI) and of 18:0, but increased levels of 18:2 and 18:3 polar lipids. Increased susceptibility to the hemi-biotrophic oomycete pathogen Phytophthora brassicae but enhanced resistance to the necrotrophic fungal pathogen Botrytis cinerea. {ECO:0000269|PubMed:19781011, ECO:0000269|PubMed:23833195}.
FunctionModulates resistance against pathogens including oomycetes (e.g. Hyaloperonospora parasitica and Phytophthora brassicae) and fungi (e.g. Phytophthora brassicae). Controls the abscisic acid-mediated (ABA) signaling pathways. Regulator of the flowering time in response to stress (e.g. UV-C). Regulates polar lipid content; promotes phosphatidylinositol (PI) and 18:0 but prevents 18:2 and 18:3 polar lipids accumulation. {ECO:0000269|PubMed:14614626, ECO:0000269|PubMed:19781011, ECO:0000269|PubMed:23833195}.
InductionRapidly up-regulated after pathogen exposure (e.g. avirulent and virulent Pseudomonas syringae pv. tomato) in a salicylic acid (SA) defense-signaling pathway-dependent manner. Circadian-regulation with accumulation during the light period, peaks of expression at the end of the day, and low levels during the dark period. Up-regulated by UV-C light through a SA-dependent process and in a CONSTANS- (CO) dependent manner. {ECO:0000269|PubMed:14614626, ECO:0000269|PubMed:19781011}.
Sequence CautionSequence=BAB03071.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
SimilarityBelongs to the CYSTM1 family. {ECO:0000305}.
Subcellular LocationCell membrane {ECO:0000305|PubMed:19933165}; Single-pass membrane protein {ECO:0000269|PubMed:19933165}.
Tissue SpecificityExpressed at very low levels in seedlings and petioles, and at higher levels in leaves. Also present in phloem sap. {ECO:0000269|PubMed:19781011, ECO:0000269|PubMed:22442409}.
