Abstract

Maize is one of the three major food or feed crops in China. Bacillus subtilis protease like serine protease (SBT) is a serine proteolytic enzyme, which widely exists in various organisms and participates in biological growth and defense. However, SBT genes functions remained uncharacterized in growth and stress response in maize. Therefore, here we characterized the SBT gene family of maize. In this study, we identified 59 maize SBT genes (ZmSBTs), which were divided into 6 subfamilies through phylogenetic analysis. ZmSBTs are distributed unevenly on 10 chromosomes in Maize. As expected, ZmSBTs contained cis-acting elements for plant growth and defense. In addition, the transcriptome data of different maize tissues shows the dynamic differential expression of ZmSBTs in different tissues. We also predicted the interaction of ZmSBT1.7 and ZmSBT2.5 specifically expressed in meiosis_tassels with other maize proteins. We revealed that the ZmSBT1.2 is specifically expressed in seeds with other maize proteins. This study provided valuable information about maize SBT gene family and clarified the possible biological functions of ZmSBT1.7, ZmSBT2.5, and ZmSBT1.2. The identified candidate genes could be used to breed higher-yielding Maize cultivars to feed the world population.

玉米SBT基因家族的全基因组鉴定、鉴定及其在各组织中的表达

玉米是中国三大粮食或饲料作物之一。枯草芽孢杆菌蛋白酶类丝氨酸蛋白酶(SBT)是一种丝氨酸水解酶，广泛存在于各种生物体中，参与生物生长和防御。然而，SBT基因在玉米生长和胁迫反应中的功能尚不明确。因此，我们对玉米的SBT基因家族进行了鉴定。本研究通过系统发育分析，鉴定出59个玉米SBT基因(zmsbt)，并将其划分为6个亚家族。zmsbt在玉米的10条染色体上分布不均匀。正如预期的那样，zmsbt含有植物生长和防御的顺式作用元件。此外，不同玉米组织的转录组数据显示，zmsbt在不同组织中的表达存在动态差异。我们还预测了在减数分裂雄穗中特异性表达的ZmSBT1.7和ZmSBT2.5与其他玉米蛋白的相互作用。我们发现ZmSBT1.2与其他玉米蛋白在种子中特异性表达。本研究为玉米SBT基因家族提供了有价值的信息，并阐明了ZmSBT1.7、ZmSBT2.5和ZmSBT1.2可能的生物学功能。鉴定出的候选基因可用于培育产量更高的玉米品种，以养活世界人口。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
