“…MAC1 (Wang et al, 2012), Ms32 (Moon et al, 2013a), and Ms33 (Xie et al, 2018) are clustered into subcluster I-2, with expression peaking at stage 6. Cluster II contains four GMS genes, namely Ms8 (Wang et al, 2013), Ms23 (Nan et al, 2017), Ms30 (Wan et al, 2014;, and ms44, which are highly expressed at stages 7-8. Cluster III is divided into two subclusters: the subcluster III-1 genes Ms9 (Albertsen et al, 2016), Ms26 (Djukanovic et al, 2013), and APV1 (Somaratne et al, 2017) are expressed highly at both stages 6 and 9, while the subcluster III-2 genes Ms6021 (Tian et al, 2017), Ms7 (Zhang et al, 2018), Ms45 (Cigan et al, 2001), IG1 (Evans, 2007), and IPE1 (Chen et al, 2017) are expressed highly at stage 9 or later.…”

As one of the most important crops, maize not only has been a source of the food, feed, and industrial feedstock for biofuel and bioproducts, but also became a model plant system for addressing fundamental questions in genetics. Male sterility is a very useful trait for hybrid vigor utilization and hybrid seed production. The identification and characterization of genic male-sterility (GMS) genes in maize and other plants have deepened our understanding of the molecular mechanisms controlling anther and pollen development, and enabled the development and efficient use of many biotechnology-based male-sterility (BMS) systems for crop hybrid breeding. In this review, we summarize main advances on the identification and characterization of GMS genes in maize, and construct a putative regulatory network controlling maize anther and pollen development by comparative genomic analysis of GMS genes in maize, Arabidopsis, and rice. Furthermore, we discuss and appraise the features of more than a dozen BMS systems for propagating male-sterile lines and producing hybrid seeds in maize and other plants. Finally, we provide our perspectives on the studies of GMS genes and the development of novel BMS systems in maize and other plants. The continuous exploration of GMS genes and BMS systems will enhance our understanding of molecular regulatory networks controlling male fertility and greatly facilitate hybrid vigor utilization in breeding and field production of maize and other crops.

The male sterility system shows tremendous value for the long-term utilization of hybrid crop breeding. In this study, a male sterile mutant, K305ms, was derived from the M3 progeny of maize (Zea mays L.) inbred line K305 exposed to 60Co-γ irradiation. Male sterile K305ms plants did not show any obvious differences from their sibling male fertile plants (K305F) during the vegetative stage, but failed to produce functional pollen at the reproductive stage. Microscopic observations determined that the dyads and tetrads from the pollen of K305ms plants developed abnormally, and subsequently the microspores were shriveled. Genetic analysis indicated that the male sterility of K305ms was controlled by a single recessive genic gene. Gene mapping showed that the responsible gene was located between two simple sequence repeat markers on chromosome 2L in a region of 10.3 cM, bnlg469b and bnlg1940, with genetic distances of 2.9 and 7.4 cM, respectively. According to the microscopic and mapping characteristics, our results showed that this gene was distinguishable from all other reported male sterile genes in maize, and it is temporarily designated as ms305. The linkage map in this study will provide a useful fundamental basis for molecular marker-assisted selection as well as for further map-based cloning of ms305.

Male sterility plays an important role in the hybrid seed production. Elucidation of the mechanism of male sterility will provide useful information for the usage of male sterility. In this study, we performed detailed phenotypic analysis of ms2 mutant, and the results showed that ms2 anthers are defects in synthesis and transportation of lipophilic molecules. To investigate the defects of transcriptome of ms2 anthers, 1.5, 2.5 and 3.5 mm anthers were sampled, respectively. Among the 23 037 expressed transcripts at 1.5 mm stage, only 15 genes were differentially expressed between fertile siblings and ms2 mutant. Compared to the fewer detected differentially expressed genes (DEGs) at 1.5 mm stage, 950 DEGs and 2212 DEGs between the fertile siblings and ms2 anthers were detected at 2.5 mm and 3.5 mm stages. These differentially expressed genes (DEGs) were mainly enriched in the secondary metabolism and lipid metabolism pathways. A series of genes related to the long‐chain fatty acids metabolism process were changed in ms2 mutant compared with the fertile siblings. The results in this study provide useful information on the mechanism of male sterility in ms2 mutant.
