Abstract Background Transcription factors (TFs) are essential regulators of growth and development in eukaryotes. Basic-helix-loop-helix (bHLHs) is one of the most significant TFs families involved in several critical regulatory functions. Cryptochrome-interacting bHLH (CIB) and cryptochromes form an extensive regulatory network to mediate a plethora of pathways. Although bHLHs regulate critical biological processes in plants, the information about pineapple bHLHs remains unexplored. Results Here, we identified a total of 121 bHLH proteins in the pineapple genome. The identified genes were renamed based on the ascending order of their gene ID and classified into 18 subgroups by phylogenetic analysis. We found that bHLH genes are expressed in different organs and stages of pineapple development. Furthermore, by the ectopic expression of AcCIB2 in Arabidopsis and complementation of Atcib2 mutant, we verified the involvement of AcCIB2 in photomorphogenesis and abiotic stress response. Conclusions Our findings revealed that AcCIB2 plays an essential role in flowering time regulation and abiotic stress response. The present study provides additional insights into the current knowledge of bHLH genes and suggests their potential role in various biological processes during pineapple development.

Background Golden2-Like (GLK) transcription factors are a type of transcriptional regulator in plants. They play a pivotal role in the plant physiological activity process and abiotic stress response. Methods In this study, the potential function of GLK family genes in Gossypium hirsutum was studied based on genomic identification, phylogenetic analysis, chromosome mapping and cis-regulatory elements prediction. Gene expression of nine key genes were analyzed by qRT-PCR experiments. Results Herein, we identified a total of 146 GhGLK genes in Gossypium hirsutum, which were unevenly distributed on each of the chromosomes. There were significant differences in the number and location of genes between the At sub-genome and the Dt sub-genome. According to the phylogenetic analysis, they were divided into ten subgroups, each of which had very similar number and structure of exons and introns. Some cis-regulatory elements were identified through promoter analysis, including five types of elements related to abiotic stress response, five types of elements related to phytohormone and five types of elements involved in growth and development. Based on public transcriptome data analysis, we identified nine key GhGLKs involved in salt, cold, and drought stress. The qRT-PCR results showed that these genes had different expression patterns under these stress conditions, suggesting that GhGLK genes played an important role in abiotic stress response. This study laid a theoretical foundation for the screening and functional verification of genes related to stress resistance of GLK gene family in cotton.

Abiotic Stress Response

Abstract Background The deubiquitinase (DUB) family constitutes a group of proteases that regulate the stability or reverse the ubiquitination of many proteins in the cell. These enzymes participate in cell-cycle regulation, cell division and differentiation, diverse physiological activities such as DNA damage repair, growth and development, and response to stress. However, limited information is available on this family of genes in woody plants. Results In the present study, 88 DUB family genes were identified in the woody model plant Populus trichocarpa, comprising 44 PtrUBP, 3 PtrUCH, 23 PtrOTU, 4 PtrMJD, and 14 PtrJAMM genes with similar domains. According to phylogenetic analysis, the PtrUBP genes were classified into 16 groups, the PtrUCH genes into two, the PtrOTU genes into eight, the PtrMJD genes into two, and the PtrJAMM genes into seven. Members of same subfamily had similar gene structure and motif distribution characteristics. Synteny analysis of the DUB family genes from P. thrchocarpa and four other plant species provided insight into the evolutionary traits of DUB genes. Expression profiles derived from previously published transcriptome data revealed distinct expression patterns of DUB genes in various tissues. On the basis of the results of analysis of promoter cis-regulatory elements, we selected 16 representative PtrUBP genes to treatment with abscisic acid, methyl jasmonate, or salicylic acid applied as a foliar spray. The majority of PtrUBP genes were upregulated in response to the phytohormone treatments, which implied that the genes play potential roles in abiotic stress response in Populus. Conclusions The results of this study broaden our understanding of the DUB family in plants. Analysis of the gene structure, conserved elements, and expression patterns of the DUB family provides a solid foundation for exploration of their specific functions in Populus and to elucidate the potential role of PtrUBP gene in abiotic stress response.
