Probable lipid transfer protein (LTP). May improve freezing survival. Seems to control the flowering process and lignin synthesis. Has an auxiliary role for germinability and early seedling development under low temperature and salt stress conditions, probably in an abscisic acid- (ABA) dependent manner. Confers resistance to Botrytis cinerea and exhibits anti-fungal activity, at least against S.cerevisiae, B. cinerea and Fusarium oxysporum, probably by increasing their membrane permeability. Mostly expressed in aerial part of seedlings, and, to a lower extent, in roots. Higher basal levels in early-flowering ecotypes. Induced during germination in embryonic tissues, and strongly expressed in certain parts of young seedlings, in the tips of cotyledons and to a certain degree in developing leaves and roots. Transient accumulation in response to toxic levels of aluminum (Al). Stably activated by vernalization; vernalization and subsequent growth in long-day photoperiods have an additive or synergistic effect on this activation. Induced by both cold and salt. Increased tendency for freezing-induced cellular damage. Reduced cutin accumulation due to lower cutin biosynthesis. Early flowering in long-day conditions. Belongs to the plant LTP family. PEARLI1 subfamily.
