“…In the current study, our data revealed that individual GmVOZ genes possessed at least one ABA-responsive element (ABRE), SA-responsive element (TCA-element) or ET-responsive element (ERE) in their promoter regions (Figure 2b and Table S2). In addition, several stress-related cis-acting elements were also identified in the promoter region of GmVOZ genes (Figure 2b and Table S2), with evidence demonstrating that these cis-elements are involved in responses to drought, salt, low temperature or pathogen attack [46][47][48][49][50][51]. In light of the existence of these cis-acting elements, GmVOZ genes are proposed to play a broad role in plant responses to abiotic and biotic stresses.…”

Vascular plant one-zinc-finger (VOZ) transcription factor, a plant specific one-zinc-finger-type transcriptional activator, is involved in regulating numerous biological processes such as floral induction and development, defense against pathogens, and response to multiple types of abiotic stress. Six VOZ transcription factor-encoding genes (GmVOZs) have been reported to exist in the soybean (Glycine max) genome. In spite of this, little information is currently available regarding GmVOZs. In this study, GmVOZs were cloned and characterized. GmVOZ genes encode proteins possessing transcriptional activation activity in yeast cells. GmVOZ1E, GmVOZ2B, and GmVOZ2D gene products were widely dispersed in the cytosol, while GmVOZ1G was primarily located in the nucleus. GmVOZs displayed a differential expression profile under dehydration, salt, and salicylic acid (SA) stress conditions. Among them, GmVOZ1G showed a significantly induced expression in response to all stress treatments. Overexpression of GmVOZ1G in soybean hairy roots resulted in a greater tolerance to drought and salt stress. In contrast, RNA interference (RNAi) soybean hairy roots suppressing GmVOZ1G were more sensitive to both of these stresses. Under drought treatment, soybean composite plants with an overexpression of hairy roots had higher relative water content (RWC). In response to drought and salt stress, lower malondialdehyde (MDA) accumulation and higher peroxidase (POD) and superoxide dismutase (SOD) activities were observed in soybean composite seedlings with an overexpression of hairy roots. The opposite results for each physiological parameter were obtained in RNAi lines. In conclusion, GmVOZ1G positively regulates drought and salt stress tolerance in soybean hairy roots. Our results will be valuable for the functional characterization of soybean VOZ transcription factors under abiotic stress.

“…Plant bHLH s modulate stress responses, including responses to LTR ( Feng et al, 2012 ; Lin et al, 2014 ; Xu et al, 2014 ), drought ( Li et al, 2007 ; Seo et al, 2011 ), heat ( Ko et al, 2009 ), and salt ( Murre et al, 1989 ; Zhou et al, 2009 ; Liu et al, 2014 ). In this work, cis -element analysis indicated that CabHLH s contained elements (such as LTR, ABRE, and TC-rich) that are responsive to various stresses, which was consistent with previous research on potato and lotus bHLH s ( Wang et al, 2018 ; Mao et al, 2019 ).…”

“…In plants, bHLH TFs are involved in various signal transduction and anabolic pathways, such as light signal transduction ( Duek and Fankhauser, 2003 ; Castillon et al, 2007 ), anthocyanin synthesis ( Ludwig et al, 1989 ; Goodrich et al, 1992 ; Quattrocchio et al, 1993 ; Nesi et al, 2000 ; Sakamoto et al, 2001 ), tryptophan synthesis ( Smolen et al, 2002 ) and gibberellin synthesis ( Arnaud et al, 2010 ). They also modulate stress responses, including responses to low temperature (LTR) ( Feng et al, 2012 ; Lin et al, 2014 ; Xu et al, 2014 ), heat ( Ko et al, 2009 ), drought ( Li et al, 2007 ; Seo et al, 2011 ), and salt ( Murre et al, 1989 ; Zhou et al, 2009 ; Liu et al, 2014 ). For example, Arabidopsis TT8 ( AtbHLH42 ) typically regulates the synthesis of anthocyanins and procyanidins of vegetative organs through the formation of MYB-bHLH-WD (MBW) complexes, specifically the TT2-TT8-TTG1 complex ( Baudry et al, 2004 ).…”

Plant basic helix-loop-helix (bHLH) transcription factors are involved in the regulation of various biological processes in plant growth, development, and stress response. However, members of this important transcription factor family have not been systematically identified and analyzed in pepper (Capsicum annuum L.). In this study, we identified 122 CabHLH genes in the pepper genome and renamed them based on their chromosomal locations. CabHLHs were divided into 21 subfamilies according to their phylogenetic relationships, and genes from the same subfamily had similar motif compositions and gene structures. Sixteen pairs of tandem and segmental duplicated genes were detected in the CabHLH family. Cis-elements identification and expression analysis of the CabHLHs revealed that they may be involved in plant development and stress responses. This study is the first comprehensive analysis of the CabHLH genes and will serve as a reference for further characterization of their molecular functions.
