水稻POD基因家族鉴定及其结构和功能分析
Identification of POD gene family and analysis of its structure and function in rice
摘要
Abstract
In order to identify members of POD gene family in rice and analyze their structural and functional characteristics,bioinformatics methods were employed to systematically analyze physicochemical properties,evolutionary relationships,chromosomal locations,promoter cis-acting elements and expression patterns of this gene family.The results were as follows:(1)A total of 64 POD gene family members were identified from rice,which were classified into 10 groups and unevenly distributed across 11 rice chromosomes.(2)Conserved motif and structural domain analysis revealed that over 50％of the members contained Motif 1,Motif 2,Motif 3,Motif 5,Motif 9,Motif 10 and Motif 14,with similar arrangement sequence;20 members possessed PL-6 superfamily structural domain,and 14 members possessed HAD-like superfamily structural domain.(3)A total of 57 regulatory elements were predicted in POD gene family,which could be categorized into light-responsive,hormone-responsive,stress-responsive,and growth and development-responsive,among which the light-responsive G-box and hormone-responsive ABRE were the most abundant.(4)Analysis of expression patterns indicated that Os03t0170900-01,Os03t0170900-02,Os06t0106800-01,Os12t0641400-01 and Os12t0641400-02 exhibited the highest overall expression levels,suggesting that they may play crucial roles in organ and tissue morphogenesis,substance transport,photosynthesis and resistance to biotic and abiotic stresses in rice.The findings of this study lay a preliminary theoretical basis for further understanding the function of rice POD genes and provide important target resources for stress resistance-oriented molecular design breeding.关键词
