Genome-Wide Analysis of the RNase T2 Family and Identification of Interacting Proteins of Four ClS-RNase Genes in 'XiangShui' Lemon.

ABSTRACT: S-RNase plays vital roles in the process of self-incompatibility (SI) in Rutaceae plants. Data have shown that the rejection phenomenon during self-pollination is due to the degradation of pollen tube RNA by S-RNase. The cytoskeleton microfilaments of pollen tubes are destroyed, and other components cannot extend downwards from the stigma and, ultimately, cannot reach the ovary to complete fertilisation. In this study, four S-RNase gene sequences were identified from the 'XiangShui' lemon genome and ubiquitome. Sequence analysis revealed that the conserved RNase T2 domains within S-RNases in 'XiangShui' lemon are the same as those within other species. Expression pattern analysis revealed that S₃-RNase and S₄-RNase are specifically expressed in th
