Identification of <i>Malus sieversii</i> ABA receptor PYL8 interacting proteome using Y2H-seq.

ABSTRACT: The seed dormancy of Malus sieversii belongs to the comprehensive type of dormancy, abscisic acid (ABA) is one of the important hormones to lift the seed dormancy. The ABA receptor pyrabactin resistance-like (PYL) protein is involved in seed germination and various stress responses. Fourteen MsPYL genes were evaluated in the genome of Malus sieversii. Phylogenetic analyses demonstrated that MsPYL proteins can be divided into three groups. The promoter regions of MsPYL genes contain cis-acting elements associated with expression induction by abiotic stresses such as abscisic acid, drought, and low temperature. Arabidopsis transgenic lines overexpressing MsPYL8 exhibited a markedly reduced germination rate, an extended growth period, and a reduction
