Abstract The cytochrome P450 (CYP450) gene family plays a vital role in basic metabolism and enhances plant resistance to stress and pests. However, little information is available on the genome-wide characterization and evolutionary relationship of the CYP450 gene family in Cucumis sativus L. In the present study, a genome-wide bioinformatics analysis was performed, including gene structure, conserved motif, cis-acting promoter element, evolutionary analysis, collinearity, subcellular localization, and expression profile. The gene expression profile of CYP450 was verified using transcriptome sequencing and quantitative reverse transcription polymerase chain reaction. A total of 165 P450 genes were identified in the cucumber genome. These genes were classified into eight subfamilies and unevenly distributed on seven chromosomes. Subcellular localization predicted that most of P450 genes were located in chloroplasts and a few were located on the plasma membrane. CYP450 genes were differentially expressed in different tissues and in response to salicylic acid (SA) treatment. The sizes of all cucumber P450 proteins ranged from 317 to 1,056 aa, the theoretical isoelectric points ranged from 5.05 to 10.31, and the molecular weights ranged from 36,095 to 121,403 KD. This study provides a theoretical basis for further research on the biological functions of the P450 gene in cucumber plants.

AbstractS-type anion channels (SLAC/SLAHs), which play important roles in plant anion (such as nitrate and chloride) transport, growth and development, abiotic stress responses and hormone signaling. However, there is far less information about this family in Rosaceae species. We performed a genome-wide analysis and identified SLAC/SLAH gene family members in pear (Pyrus bretschneideri) and four other species of Rosaceae (Malus domestica, Prunus persica, Fragaria vesca and Prunus mume). A total of 21 SLAC/SLAH genes were identified from the five Rosaceae species. Based on the structural characteristics and a phylogenetic analysis of these genes, the SLAC/SLAH gene family could be classified into three main groups (I, II and III). The evolutionary analysis showed that the SLAC/SLAH gene family was comparatively conserved during the evolution of Rosaceae species. Transcriptome data demonstrated that PbrSLAC/SLAH genes were detected in all parts of the pear. However, PbrSLAC1 showed a higher expression level in leaf, while PbrSLAH2/3 was mainly expressed in roots. In addition, PbrSLAC/SLAH genes were only located on the plasma membrane in transient expression experiments in Arabidopsis protoplasts cells. These results provide valuable information that increases our understanding of the evolution, expression and functions of the SLAC/SLAH gene family in higher plants.

In plants, the mechanosensitive channels have important roles in proprioception, gravity sensing, growth of pollen tube and controlling the shape and size of plastid. In the present study, we performed computational analysis and identified the mechanosensitive channel of small conductance like (MscS) gene family in Cicer arietinum (chickpea). Six Cicer arietinum MscS-like (CaMSL) genes were identified. These six genes were distributed on four different chromosomes. A detailed overview of CaMSL genes in Cicer arietinum is explored by using a total of 33107 proteins from chickpea. On the basis of BLAST analysis, presence of complete ORF and evolutionary relationship we identified 6 genes (named as CaMSL1, CaMSL2, CaMSL3, CaMSL4, CaMSL5 and CaMSL6). Further, the transmembrane regions, subcellular localization, physico-chemical properties, gene structure analysis and genome structure annotation of the identified genes confirmed that the identified genes might act for transmembrane proteins as well as their subcellular localization prediction demonstrated three genes to be located in the plasma membrane, two in the chloroplast membrane, one in the mitochondrion. Thus, further analysis of the data obtained from this study will help to make a baseline to increase the understanding of involvement of MSL gene families in plant growth, development and other functions in C. arietinum.

Monodehydroasorbate reductase (MDHAR) (EC1.6.5.4), a key enzyme in ascorbate-glutathione recycling, plays important roles in cell growth, plant development and physiological response to environmental stress via control of ascorbic acid (AsA)-mediated reduction/oxidation (redox) regulation. Until now, information regarding MDHAR function and regulatory mechanism in Gossypium have been limited. Herein, a genome-wide identification and comprehensive bioinformatic analysis of 36 MDHAR family genes in four Gossypium species, Gossypium arboreum, G. raimondii, G. hirsutum, and G. barbadense, were performed, indicating their close evolutionary relationship. Expression analysis of GhMDHARs in different cotton tissues and under abiotic stress and phytohormone treatment revealed diverse expression features. Fiber-specific expression analysis showed that GhMDHAR1A/D, 3A/D and 4A/D were preferentially expressed in fiber fast elongating stages to reach peak values in 15-DPA fibers, with corresponding coincident observances of MDHAR enzyme activity, AsA content and ascorbic acid/dehydroascorbic acid (AsA/DHA) ratio. Meanwhile, there was a close positive correlation between the increase of AsA content and AsA/DHA ratio catalyzed by MDHAR and fiber elongation development in different fiber-length cotton cultivars, suggesting the potential important function of MDHAR for fiber growth. Following H2O2 stimulation, GhMDHAR demonstrated immediate responses at the levels of mRNA, enzyme, the product of AsA and corresponding AsA/DHA value, and antioxidative activity. These results for the first time provide a comprehensive systemic analysis of the MDHAR gene family in plants and the four cotton species and demonstrate the contribution of MDHAR to fiber elongation development by controlling AsA-recycling-mediated cellular redox homeostasis.

Abstract Background Cyclin-dependent kinases (CDKs) are protein kinases regulating important cellular processes such as cell cycle and transcription. Many CDK genes also play a critical role during adipogenic differentiation, but the role of CDK gene family in regulating bovine adipocyte differentiation has not been studied. Therefore, the present study aims to characterize the CDK gene family in bovine and study their expression pattern during adipocyte differentiation. Results We performed a genome-wide analysis and identified a number of CDK genes in several bovine species. The CDK genes were classified into 8 subfamilies through phylogenetic analysis. We found that 25 bovine CDK genes were distributed in 16 different chromosomes. Collinearity analysis revealed that the CDK gene family in Bos taurus is homologous with Bos indicus, Hybrid-Bos taurus, Hybrid Bos indicus, Bos grunniens and Bubalus bubalis. Several CDK genes had higher expression levels in preadipocytes than in differentiated adipocytes, as shown by RNA-seq analysis and qPCR, suggesting a role in the growth of emerging lipid droplets. Conclusion In this research, 185 CDK genes were identified and grouped into eight distinct clades in Bovidae, showing extensively homology. Global expression analysis of different bovine tissues and specific expression analysis during adipocytes differentiation revealed CDK4, CDK7, CDK8, CDK9 and CDK14 may be involved in bovine adipocyte differentiation. The results provide a basis for further study to determine the roles of CDK gene family in regulating adipocyte differentiation, which is beneficial for beef quality improvement.

Abstract Main conclusion Chitinase family genes were involved in the response of Brassica oleracea to Fusarium wilt, powdery mildew, black spot and downy mildew. Abstract Abstract Chitinase, a category of pathogenesis-related proteins, is believed to play an important role in defending against external stress in plants. However, a comprehensive analysis of the chitin-binding gene family has not been reported to date in cabbage (Brassica oleracea L.), especially regarding the roles that chitinases play in response to various diseases. In this study, a total of 20 chitinase genes were identified using a genome-wide search method. Phylogenetic analysis was employed to classify these genes into two groups. The genes were distributed unevenly across six chromosomes in cabbage, and all of them contained few introns (≤ 2). The results of collinear analysis showed that the cabbage genome contained 1–5 copies of each chitinase gene (excluding Bol035470) identified in Arabidopsis. The heatmap of the chitinase gene family showed that these genes were expressed in various tissues and organs. Two genes (Bol023322 and Bol041024) were relatively highly expressed in all of the investigated tissues under normal conditions, exhibiting the expression characteristics of housekeeping genes. In addition, under four different stresses, namely, Fusarium wilt, powdery mildew, black spot and downy mildew, we detected 9, 5, 8 and 8 genes with different expression levels in different treatments, respectively. Our results may help to elucidate the roles played by chitinases in the responses of host plants to various diseases.
