Identification of 1,3-1,4-β-D-glucanase (OsDLH) genes and analysis of haplotype diversity in rice.

ABSTRACT: 1,3-1,4-β-D-glucanase (DLH) is a fibrolytic enzyme playing important roles in plant growth, development, and stress response. In this study, we identified 11 DLH genes in japonica rice (Nipponbare), and analyzed their chromosomal localization, physicochemical properties, subcellular localization, evolutionary relationships, and collinearity. We also performed cis-acting element identification, gene expression profiling, and qPCR verification under abiotic stress, as well as conducted diversity analysis of gene-CDS-haplotypes (gcHaps) in 3,010 rice germplasms to dissect the potential functions of these OsDLH genes. The results showed that OsDLH1, OsDLH5, and OsDLH10 can be utilized to improve the tolerance of rice to abiotic stress. OsDLH1
