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 Background: WRKY transcription factors are a superfamily of regulators involved in diverse biological processes and stress responses in plants. However, knowledge is limited for WRKY family in camelina (Camelina sativa), an important Brassicaceae oil crop with strong tolerance against various stresses. Here, genome-wide characterization of WRKY proteins is performed to examine their gene-structures, phylogenetics, expressions, conserved motif organizations, and functional annotation to identify candidate WRKYs mediating regulation of stress resistance in camelina.Results: Total of 242 CsWRKY proteins encoded by 224 gene loci distributed uneven on chromosomes were identified, and classified into three groups via phylogenetic analysis according to their WRKY domains and zinc finger motifs. 15 CsWRKY gene loci generated 33 spliced variants. Orthologous WRKY gene pairs were identified, with 173 pairs in C. sativa and Arabidopsis genomes as well as 282 pairs for C. sativa and B. napus, respectively. 137 segmental duplication events were observed but no tandem duplication in camelina genome. Ten major conserved motifs were examined, with WRKYGQK as the most conserved and several variants existed in many CsWRKYs. Expression analysis revealed that half more CsWRKY genes were expressed constitutively, and a set of them had a tissue-specific expression. Notably, 11 CsWRKY genes exhibited significantly expression changes in plant seedlings under cold, salt, and drought stress, respectively, having preferentially inducible expression pattern in response to the stress.Conclusions: The present described a detail analysis of CsWRKY gen family and their expression profiled in twelve tissues and under several stress conditions. Segmental duplication is the major force for large expansion of this gene family, and a strong purifying pressure happened for CsWRKY proteins evolutionally. CsWRKY proteins play important roles for plant development, with differential functions in different tissues. Exceptionally, eleven CsWRKYs, particularly five alternative spliced isoforms were found to be the key players possibly in mediating plant response to various stresses. Overall, our results provide a foundation for understanding roles of CsWRKYs and the precise mechanism through which CsWRKYs regulate high stress resistance to stress as well as development of stress tolerance cultivars for Cruciferae crops.

The plant-specific transcription factor TCPs play multiple roles in plant growth, development, and stress responses. However, a genome-wide analysis of TCP proteins and their roles in salt stress has not been declared in switchgrass (Panicum virgatum L.). In this study, 42 PvTCP genes (PvTCPs) were identified from the switchgrass genome and 38 members can be anchored to its chromosomes unevenly. Nine PvTCPs were predicted to be microRNA319 (miR319) targets. Furthermore, PvTCPs can be divided into three clades according to the phylogeny and conserved domains. Members in the same clade have the similar gene structure and motif localization. Although all PvTCPs were expressed in tested tissues, their expression profiles were different under normal condition. The specific expression may indicate their different roles in plant growth and development. In addition, approximately 20 cis-acting elements were detected in the promoters of PvTCPs, and 40% were related to stress response. Moreover, the expression profiles of PvTCPs under salt stress were also analyzed and 29 PvTCPs were regulated after NaCl treatment. Taken together, the PvTCP gene family was analyzed at a genome-wide level and their possible functions in salt stress, which lay the basis for further functional analysis of PvTCPs in switchgrass.

Globulin Gene

The rat alpha 2u globulin gene family encodes approximately 20 low-molecular-weight (20,000) proteins with pIs ranging from 4.5 to 7.9. alpha 2u globulin protein isoforms were detected in the liver and in the submaxillary, lachrymal, preputial, and mammary glands of Sprague-Dawley rats. The hormonal and developmental regulation of alpha 2u globulin synthesis in each of these tissues was unique, and it appears that different alpha 2u gene sets were transcribed in the various tissues.
