“…With the exception of EgrGRAS51 , all 18 EgrGRAS genes showed significant differences in expression after low-temperature stress treatment compared with normal conditions. The work showed that the expression level of PbGRAS14 in Phoebe bournei increased significantly under low temperature stress [ 44 ]. Huang et al also found that SlGRAS1 , SlGRAS3 and SlGRAS4 in tomato can actively respond to low temperature stress, indicating that these genes were widely involved in low temperature resistance [ 23 ].…”

Background The GRAS gene family is a class of plant-specific transcription factors with important roles in many biological processes, such as signal transduction, disease resistance and stress tolerance, plant growth and development. So far, no information available describes the functions of the GRAS genes in Eucalyptus grandis. Results A total of 82 GRAS genes were identified with amino acid lengths ranging from 267 to 817 aa, and most EgrGRAS genes had one exon. Members of the GRAS gene family of Eucalyptus grandis are divided into 9 subfamilies with different protein structures, while members of the same subfamily have similar gene structures and conserved motifs. Moreover, these EgrGRAS genes expanded primarily due to segmental duplication. In addition, cis-acting element analysis showed that this family of genes was involved involved in the signal transduction of various plant hormones, growth and development, and stress response. The qRT-PCR data indicated that 18 EgrGRAS genes significantly responded to hormonal and abiotic stresses. Among them, the expression of EgrGRAS13, EgrGRAS68 and EgrGRAS55 genes was significantly up-regulated during the treatment period, and it was hypothesised that members of the EgrGRAS family play an important role in stress tolerance. Conclusions In this study, the phylogenetic relationship, conserved domains, cis-elements and expression patterns of GRAS gene family of Eucalyptus grandis were analyzed, which filled the gap in the identification of GRAS gene family of Eucalyptus grandis and laid the foundation for analyzing the function of EgrGRAS gene in hormone and stress response.

The bZIPgene family plays a crucial role in supporting plant life as one of the most important transcription factors. Its involvement in various processes such as light signaling, seed maturation, flower development, and cell elongation has been established, but limited to perennial and agricultural crops. This study focused on the classification of 71 bZIP genes across 12 chromosomes based on their evolutionary relationships. Each group exhibited distinct gene structures and variations in the number of conserved motifs. The presence of multiple cis-acting elements suggested that the PbbZIP gene family played a vital role in hormonal and regulatory signaling, which were essential for plant growth, development, and resilience against abiotic stress. RNA and qPCR analysis revealed expression levels of PbbZIP32, PbbZIP14, PbbZIP26, PbbZIP67, and PbbZIP69 under salt, drought, and temperature stress conditions. This research contributed to a deeper understanding of the underlying mechanisms governing stress resistance, growth, and development processes mediated by the bZIP gene family. It also can serve as a foundation for future investigations on the bZIPgene family in forestry species.

“…To investigate the response of the PbPIN gene family to abiotic stresses such as drought, salt, and temperature stresses, we focused on five genes (PbPIN1, PbPIN7, PbPIN8, PbPIN9, and PbPIN11) that contained a higher number of elements associated with adversity in their cis-acting elements [22,47]. These five genes were considered to be representative of four different sub-families.…”

PIN-formed (PIN) proteins—specific transcription factors that are widely distributed in plants—play a pivotal role in regulating polar auxin transport, thus influencing plant growth, development, and abiotic stress responses. Although the identification and functional validation of PIN genes have been extensively explored in various plant species, their understanding in woody plants—particularly the endangered species Phoebe bournei (Hemsl.) Yang—remains limited. P. bournei is an economically significant tree species that is endemic to southern China. For this study, we employed bioinformatics approaches to screen and identify 13 members of the PIN gene family in P. bournei. Through a phylogenetic analysis, we classified these genes into five sub-families: A, B, C, D, and E. Furthermore, we conducted a comprehensive analysis of the physicochemical properties, three-dimensional structures, conserved motifs, and gene structures of the PbPIN proteins. Our results demonstrate that all PbPIN genes consist of exons and introns, albeit with variations in their number and length, highlighting the conservation and evolutionary changes in PbPIN genes. The results of our collinearity analysis indicate that the expansion of the PbPIN gene family primarily occurred through segmental duplication. Additionally, by predicting cis-acting elements in their promoters, we inferred the potential involvement of PbPIN genes in plant hormone and abiotic stress responses. To investigate their expression patterns, we conducted a comprehensive expression profiling of PbPIN genes in different tissues. Notably, we observed differential expression levels of PbPINs across the various tissues. Moreover, we examined the expression profiles of five representative PbPIN genes under abiotic stress conditions, including heat, cold, salt, and drought stress. These experiments preliminarily verified their responsiveness and functional roles in mediating responses to abiotic stress. In summary, this study systematically analyzes the expression patterns of PIN genes and their response to abiotic stresses in P. bournei using whole-genome data. Our findings provide novel insights and valuable information for stress tolerance regulation in P. bournei. Moreover, the study offers significant contributions towards unraveling the functional characteristics of the PIN gene family.
