Genome-wide analysis of maize GPAT gene family and cytological characterization and breeding application of ZmMs33/ZmGPAT6 gene.

Glycerol-3-phosphate acyltransferase (GPAT) mediates the initial step of glycerolipid biosynthesis and plays pivotal roles in plant growth and development. Compared with GPAT genes in Arabidopsis, our understanding to maize GPAT gene family is very limited. Recently, ZmMs33 gene has been identified to encode a sn-2 GPAT protein and control maize male fertility in our laboratory (Xie et al. in Theor Appl Genet 131:1363-1378, 2018). However, the functional mechanism of ZmMs33 remains elusive. Here, we reported the genome-wide analysis of maize GPAT gene family and found that 20 maize GPAT genes (ZmGPAT1-20) could be classified into three distinct clades similar to those of ten GPAT genes in Arabidopsis. Expression analyses of these ZmGPAT genes in six tissues and in anther during six developmental stages suggested that some of ZmGPATs may play crucial roles in maize growth and anther development. Among them, ZmGPAT6 corresponds to the ZmMs33 gene. Systemic cyto...
