“…Only in three transcriptomes from the root, stem, and leaf were there as many as 140 bHLH transcripts, which could result from alternative splicing events [ 13 ]. Compared with other TF families identified in D. officinale , the number of bHLH family members ranked second, after the MYB family [ 46 ], and was greater than other families such as GRAS [ 10 ] and MADS [ 47 ]. The number of bHLH members in D. officinale was similar to that in jujube [ 25 ] and peach [ 44 ] and was more than in Carthamus tinctorius [ 48 ].…”

Dendrobium officinale Kimura et Migo is of great importance as a traditional Chinese herb due to its abundant metabolites. The family of basic helix-loop-helix (bHLH) transcription factors widely exists in plants and plays an essential role in plant growth and development, secondary metabolism as well as responses to environmental changes. However, there is limited information on bHLH genes in D. officinale. In the present study, a total of 98 putative DobHLH genes were identified at the genomic level, which could be classified into 18 clades. Gene structures and conserved motifs in DobHLH genes showed high conservation during their evolution. The conserved amino acids and DNA bindings of DobHLH proteins were predicted, both of which are pivotal for their function. Furthermore, gene expression from eight tissues showed that some DobHLH genes were ubiquitously expressed while other DobHLH genes were expressed in the specific tissues. Expressional changes of DobHLH genes under MeJA and ABA treatments were detected by qRT-PCR. The protein–protein interactions between DobHLHs were predicted and several interactions were confirmed by yeast two hybrid. Therefore, our results here contribute to the understanding of bHLH genes in D. officinale and lay a foundation for the further functional study of its biological processes.

“…Transcription factors have emerged as critical regulatory factors governing various aspects of plant growth, development, and response to abiotic stress. Several studies have focused on exploring transcription factor families in D. catenatum, including AP2/ERF, WOX, TCP, MYB, LBD, WRKY, HD-ZIP, MADS-box, and bHLH [40][41][42][43][44][45][46][47]. However, the characterization of the NAC transcription factor family in RJ remains unexplored.…”

Dendrobium catenatum is a highly drought-tolerant herb, which usually grows on cliffs or in the branches of trees, yet the underlying molecular mechanisms for its tolerance remain poorly understood. We conducted a comprehensive study utilizing whole-transcriptome sequencing approaches to investigate the molecular response to extreme drought stress in D. catenatum. A large number of differentially expressed mRNAs, lncRNAs, and circRNAs have been identified, and the NAC transcription factor family was highly enriched. Meanwhile, 46 genes were significantly up-regulated in the ABA-activated signaling pathway. In addition to the 89 NAC family members accurately identified in this study, 32 members were found to have different expressions between the CK and extreme drought treatment. They may regulate drought stress through both ABA-dependent and ABA-independent pathways. Moreover, the 32 analyzed differentially expressed DcNACs were found to be predominantly expressed in the floral organs and roots. The ceRNA regulatory network showed that DcNAC87 is at the core of the ceRNA network and is regulated by miR169, miR393, and four lncRNAs. These investigations provided valuable information on the role of NAC transcription factors in D. catenatum’s response to drought stress.

“…These cues are all important for flowering transition; therefore, AS plays multiple roles in flowering by integrating endogenous developmental and exogenous environmental signals. The flowering inhibitor gene flowering locus c (FLC) encodes a MADS-box transcription factor and is a key regulator of vernalisation and autonomous pathways in Arabidopsis and related species (Michaels and Amasino, 1999;Sheldon et al, 1999;Sheldon et al, 2000;Chen et al, 2019;Coupland, 2019). FLC inhibits flowering by repressing the expression of a subset of key genes in promoting flowering, such as flowering locus t (FT), suppressor of overexpression of constans 1 (SOC1) and target of flc and svp1 (TFS1) (Helliwell et al, 2006;Searle et al, 2006;Luo et al, 2019;Richter et al, 2019).…”

Flowering is a critical stage of plant development and is closely correlated with seed production and crop yield. Flowering transition is regulated by complex genetic networks in response to endogenous and environmental signals. FLOWERING LOCUS C (FLC) is a central repressor in the flowering transition of Arabidopsis thaliana. The regulation of FLC expression is well studied at transcriptional and post-transcriptional levels. A subset of antisense transcripts from FLC locus, collectively termed cold-induced long antisense intragenic RNAs (COOLAIR), repress FLC expression under cold exposure. Recent studies have provided important insights into the alternative splicing of COOLAIR and FLC sense transcripts in response to developmental and environmental cues. Herein, at the 20th anniversary of FLC functional identification, we summarise new research advances in the alternative splicing of FLC sense and antisense transcripts that regulates flowering.
