G. X. E, Zhao, Y. J., Ma, Y. H., Cao, G. L., He, J. N., Na, R. S., Zhao, Z. Q., Jiang, C. D., Zhang, J. H., Arlvd, S., Chen, L. P., Qiu, X. Y., Hu, W., Huang, Y. F., E, G. X., Zhao, Y. J., Ma, Y. H., Cao, G. L., He, J. N., Na, R. S., Zhao, Z. Q., Jiang, C. D., Zhang, J. H., Arlvd, S., Chen, L. P., Qiu, X. Y., Hu, W., and Huang, Y. F., “Desmoglein 4 diversity and correlation analysis with coat color in goat”, vol. 15, p. -, 2016.

Desmoglein 4 (DSG4) has an important role in the development of wool traits in domestic animals. The full-length DSG4 gene, which contains 3918 bp, a complete open-reading-frame, and encodes a 1040-amino acid protein, was amplified from Liaoning cashmere goat. The sequence was compared with that of DSG4 from other animals and the results show that the DSG4 coding region is consistent with interspecies conservation.

Genomic identification of group A bZIP transcription factors and their responses to abiotic stress in carrot

F. Que, Wang, G. L., Huang, Y., Xu, Z. S., Wang, F., and Xiong, A. S., “Genomic identification of group A bZIP transcription factors and their responses to abiotic stress in carrot”, vol. 14, pp. 13274-13288, 2015.

The basic-region/leucine-zipper (bZIP) family is one of the major transcription factor (TF) families associated with responses to abiotic stresses. Many members of group A in this family have been extensively examined and are reported to perform significant functions in ABA signaling as well as in responses to abiotic stresses. In this study, 10 bZIP factors in carrot were classified into group A based on their DNA-binding domains. The cis-acting regulatory elements and folding states of these 10 factors were analyzed.

Large-scale detection and application of expressed sequence tag single nucleotide polymorphisms in Nicotiana

Y. Wang, Zhou, D., Wang, S., and Yang, L., “Large-scale detection and application of expressed sequence tag single nucleotide polymorphisms in Nicotiana”, vol. 14, pp. 7793-7800, 2015.

Single nucleotide polymorphisms (SNPs) are widespread in the Nicotiana genome. Using an alignment and variation detection method, we developed 20,607,973 SNPs, based on the expressed sequence tag sequences of 10 Nicotiana species. The replacement rate was much higher than the transversion rate in the SNPs, and SNPs widely exist in the Nicotiana. In vitro verification indicated that all of the SNPs were high quality and accurate.

In silico identification and analysis of phytoene synthase genes in plants

Y. Han, Zheng, Q. S., Wei, Y. P., Chen, J., Liu, R., and Wan, H. J., “In silico identification and analysis of phytoene synthase genes in plants”, vol. 14, pp. 9412-9422, 2015.

In this study, we examined phytoene synthetase (PSY), the first key limiting enzyme in the synthesis of carotenoids and catalyzing the formation of geranylgeranyl pyrophosphate in terpenoid biosynthesis. We used known amino acid sequences of the PSY gene in tomato plants to conduct a genome-wide search and identify putative candidates in 34 sequenced plants. A total of 101 homologous genes were identified. Phylogenetic analysis revealed that PSY evolved independently in algae as well as monocotyledonous and dicotyledonous plants.

Evolutionary analysis of the ubiquitin gene of baculovirus and insect hosts

S. S. Ma, Zhang, Z., Xia, H. C., Chen, L., Yang, Y. H., Yao, Q., and Chen, K. P., “Evolutionary analysis of the ubiquitin gene of baculovirus and insect hosts”, vol. 14, pp. 9963-9973, 2015.

Baculovirus is the only virus that has been found to encode the ubiquitin protein. In this study, ubiquitin sequences from 16 insects and 49 viruses were collected and compared. The resulting sequences were aligned with virus genomes. Then MAGE 5.0, k-estimated software, as well as other software programs were used for systemic evolutionary, selection pressure, and evolutionary distance analysis.

Development of EST-SSR markers related to disease resistance and their application in genetic diversity and evolution analysis in Gossypium

B. H. Wang, Rong, P., Cai, X. X., Wang, W., Zhu, X. Y., Chen, C. J., Xu, Y. Y., Huang, X. J., Zhuang, Z. M., and Wang, C. B., “Development of EST-SSR markers related to disease resistance and their application in genetic diversity and evolution analysis in Gossypium”, vol. 14, pp. 10630-10644, 2015.

Cotton (Gossypium spp) is one of the most economically important crops that provide the world’s most widely used natural fiber. Diseases such as Fusarium wilt and particularly Verticillium wilt seriously affect cotton production, and thus breeding for disease resistance is one of the most important goals of cotton breeding programs. Currently, potential exists to improve disease resistance in cultivated cotton.
