Background: Nucleobase-ascorbate transporters(NAT), synonymously called nucleobase-cation symporter 2(NCS2) proteins, were earlier reported to be involved in plant growth, development and resistance to stress. Previous studies concluded that s a polymorphic SNP associated with NAT12 was significant di erent between salt-tolerant and salt-sensitive materials of upland cotton. In current study, a comprehensive analysis of NAT family genes was conducted for the first time in ***: In this study, we discovered 32, 32, 18, and 16 NAT genes in Gossypium hirsutum, G. barbadense, G. raimondii and G. arboreum, respectively, which were classified into four groups(groups I–IV) based on the multiple sequence analysis. These GhNAT genes were unevenly distributed on At and Dt sub-genome in G. hirsutum. Most GhNAT members in the same group had similar gene structure characteristics and motif composition. The collinearity analysis revealed segmental duplication as well as tandem duplication contributing to the expansion of the GhNATs. The analysis of cis-acting regulatory elements of GhNATs showed that the function of GhNAT genes in cotton might be related to plant hormone and stress response. Under di erent conditions, the expression levels further suggested the GhNAT family genes were associated with plant response to various abiotic stresses. GhNAT12 was detected in the plasma membrane. And it was validated that the GhNAT12 gene played an important role in regulating cotton resistance to salt and drought stress through the virus-induced gene silencing(VIGS) ***: A comprehensive analysis of NAT gene family was performed in cotton, including phylogenetic analysis, chromosomal location, collinearity analysis, motifs, gene structure and so on. Our results will further broaden the insight into the evolution and potential functions of NAT genes in cotton. Current findings could make significant contribution towards screening more candidate genes related to b

为了解海岛棉GbPLA1-32基因结构特征及功能,本研究以海岛棉‘海7124’为实验材料,利用前期耐盐转录组测序结果筛选得到差异表达基因并进行克隆。通过生物信息学分析,获得‘海7124’GbPLA1-32基因全长CDS,分析该基因编码蛋白的理化性质、鉴定其亲水性与疏水性,对磷酸化和糖基化位点、信号肽和跨膜区以及蛋白质结构进行预测,确定亚细胞定位并构建系统进化树。结果表明,该基因编码区全长1530 bp,编码509个氨基酸,编码蛋白在磷脂酶A1家族,属α/β-水解酶超家族。它属于亲水性蛋白,不存在明显信号肽且不具有跨膜结构,亚细胞定位于叶绿体中。同时,α-螺旋、延伸链、β-转角和无规则卷曲这4个元件构成了Gb PLA1-32蛋白的二级结构。进化树分析表明海岛棉与陆地棉亲缘关系最为接近,根据其编码蛋白将该基因命名为GbPLA1-32。RT-qPCR分析结果表明,GbPLA1-32基因能够对PEG和盐两种胁迫做出响应。本研究结果可为进一步阐明GbPLA1-32在海岛棉中的生物学功能提供参考。

A genome-wide analysis of SWEET gene family in cotton and their expressions under different stresses

Journal of Cotton Research 2018年第2期1卷 12-26页

Background： The SWEET （Sugars will eventually be exported transporters） gene family plays multiple roles in plant physiological activities and development process. It participates in reproductive development and in the process of sugar transport and absorption, plant senescence and stress responses and plant-pathogen interaction. However, thecomprehensive analysis of SWEET genes has not been reported in cotton. Results： In this study, we identified 22, 31, 55 and 60 SWEETgenes from the sequenced genomes of Gossypium orboreum, G. rairnondii, G. hirsutum and G. borbadense, respectively. Phylogenetic tree analysis showed that the SWEET genes could be divided into four groups, which were further classified into 14 sub-clades. Further analysis of chromosomal location, synteny analysis and gene duplication suggested that the orthologs showed a good collinearity and segmental duplication events played a crucial role in the expansion of the family in cotton. Specific MtN3_slv domains were highly conserved between Arabidopsis and cotton by exon-intron organization and motif analysis. In addition, the expression pattern in different tissues indicated that the duplicated genes in cotton might have acquired new functions as a result of sub-functionalization or neo-functionalization. The expression pattern of SWEET genes showed that the different genes were induced by diverse stresses. The identification and functional analysis of SWEET genes in cotton may provide more candidate genes for genetic modification. Conclusion： SWEET genes were classified into four clades in cotton. The expression patterns suggested that the duplicated genes might have experienced a functional divergence. This work provides insights into the evolution of SWEETgenes and more candidates for specific genetic modification, which will be useful in future research.
