osa-miR408-3p: Osa-mir408-3p is a microRNA that has been identified in rice plants and has been found to be highly expressed in various tissues and under different abiotic stresses [PMC7526420]. It has been shown to be downregulated during chilling stress in rice plants, which may lead to oxidative damage and impair the photosynthetic process [PMC9002458]. Osa-mir408-3p is known to target the gene OsPYL6 and is involved in cell elongation in rice seeds [PMC10116700]. It has also been found to be differentially expressed in heat-tolerant genotypes, suggesting a potential role in the recovery response [PMC5447883]. Osa-mir408-3p has been shown to be involved in disease resistance mechanisms, as its downregulation was observed during infection with R. solani [PMC9189367]. Additionally, it has been found to be upregulated during tiller development and involved in abiotic stress responses [PMC7539525]. Osa-mir408-3p is also upregulated under cadmium stress and may play a role in Cd accumulation [PMC7003353]. Overall, osa-mir408-3p appears to have diverse functions and plays a role in various physiological processes.
