Genomic analysis of Asian honeybee populations in China reveals evolutionary relationships and adaptation to abiotic stress

SUMO-conjugating enzymes (SCE) and SUMO (Small Ubiquitin-Like Modifiers) genes are important components of SUMOylation. SCE has a crucial role during the SUMOylation process which acts as a catalyst to transfer SUMO to the target protein. Comprehensive studies on SCE and SUMO have been performed in some plants, but studies on these genes remain limited in potato. This study is aimed at exploring the role of StSCE and StSUMO genes in abiotic stress conditions. Nine and seven putative StSCEs and StSUMO genes, respectively, were identified using different methods and databases available for potato. Chromosomal localization showed that SCE and StSUMO genes are unevenly distributed on 7 different chromosomes. Potato genome database was accessed for the expression profile of StSCE and StSUMO genes, and these genes were differentially expressed in different tissues and organs during different phases of plant growth. The expression patterns on different treatments were further evaluated using qRT-PCR for all the StSCE and StSUMO genes. The expression was upregulated in StSCE1/5/6 and 7 under salt and PEG treatment. StSUMO 1/2 and 4 were upregulated under salt stress whereas StSCE9 and StSUMO2 and 4 were observed downregulated under PEG treatment. The results of this study could be useful to explore the role of StSCE genes in potato improvement.

Somatostatin 14

There is now evidence for the existence of two somatostatin genes in most vertebrate species, and even three somatostatin genes in teleosts. To help clarify the evolutionary relationships between the different somatostatin isoforms currently known, we characterized the somatostatin loci in a teleost species, the zebrafish Danio rerio, and compared them with the corresponding regions in the human and pufferfish genomes. The occurrence of three somatostatin genes, termed SS1, SS2 and SSII, has been previously demonstrated in the zebrafish. Radiation hybrid mapping assigned these three genes to linkage groups 15, 23 and 2, respectively. Conserved synteny of the zebrafish SS2 gene and the human cortistatin gene was revealed by comparative genomic analysis, indicating that mammalian cortistatin is orthologous to the SS2 variant of non-mammalian species. In contrast, using a similar approach, it was not possible to identify the evolutionary relationships between the atypical SSII gene of zebrafish and the other teleost SSII genes.
