“…The COL gene family is widely distributed and the members vary greatly among different plant species. For example, 17 COL genes were identified in Arabidopsis thaliana ( Griffiths et al, 2003 ), 9 in barley ( Griffiths et al, 2003 ), 16 in rice ( Griffiths et al, 2003 ), 26 in soybean ( Wu et al, 2014 ), 42 in cotton ( Cai et al, 2017 ), 19 in maize ( Song et al, 2018 ), 20 in radish ( Hu et al, 2018 ), 13 in tomato ( Yang et al, 2020 ), and 22 in sunflower ( Niu et al, 2022 ). COL genes are characterized based on two conservative domains.…”

“…After the angiosperm whole-genome duplication (WGD) events, the first B-box domain in group I and the second B-box domain in group III were lost in some plant species ( Song et al, 2015 ). Differentiation of the B-box domain has a crucial role in the phyletic evolution of COL genes ( Song et al, 2015 ; Niu et al, 2022 ).…”

“…OsCOL9 was reported to regulate disease resistance dependent on ethylene and salicylic acid (SA) signaling pathways ( Liu H. et al, 2016 ). BnCOL2 in Brassica napus responded to drought stress ( Liu et al, 2020 ), while HaCOL3 , HaCOL6 , and HaCOL19 were induced by cadmium (Cd), heat, and drought stresses in sunflower ( Niu et al, 2022 ). In adapting to adverse environments, COL genes have developed essential new functions in response to abiotic stresses.…”

Genome-Wide Identification and Expression Profiling of CONSTANS-Like Genes in Pepper (Capsicum annuum): Gaining an Insight to Their Phylogenetic Evolution and Stress-Specific Roles

CONSTANS-like (COL) genes play important regulatory roles in multiple growth and development processes of plants but have rarely been studied in Capsicum annuum. This study explored the evolutionary relationship and expression patterns of COL genes from C. annuum. A total of 10 COL genes were identified in the genome of the cultivated pepper Zunla-1 and were named CaCOL01–10. These genes were unequally distributed among five chromosomes and could be divided into three groups based on differences in gene structure characteristics. During evolutionary history, duplications and retentions were divergent among different groups of COL genes. Tandem duplication caused amplification of group I genes. Genetic distance among COL genes was the largest in group III, suggesting that group III genes undergo more relaxed selection pressure compared with the other groups. Expression patterns of CaCOLs in tissues were significantly different, with CaCOL08 exhibiting the highest expression in stem and leaf. Some COL orthologous genes showed markedly different expression patterns in pepper compared with tomato, such as COL_1 orthologs, which may be involved in fruit development in pepper. In addition, CaCOLs participated in the regulation of abiotic stresses to varying degrees. Five CaCOL genes were induced by cold, and CaCOL02 and CaCOL03 were specifically upregulated by cold and downregulated by heat. This study provides a theoretical basis for the in-depth understanding of the functions of COL genes in pepper and their molecular mechanisms involved in growth and development and responses to abiotic stresses.

“…The plants were grown under normal culture conditions following the above method until the sunflower seedlings grew to express six true leaves. For the heat and drought stress experiments, the treatments were conducted following the methods outlined in our previous study ( Niu et al, 2022 ). For the cold stress experiment, seedlings with similar growth characteristics were selected and treated at 4°C for 8, 16, and 32 h (denoted C8, C16, and C32, respectively).…”

Jasmonate ZIM-domain (JAZ) proteins act as inhibitory factors of the jasmonic acid (JA) pathway, which is involved in regulating plant development and defense responses. However, there are no extensive studies available on JAZ genes in sunflower (Helianthus annuus L.). In this study, the phylogenetic analysis of 139 putative JAZ genes from eight plants demonstrated that these JAZs could be divided into five groups (Groups I–V), and the 27 sunflower JAZs (HaJAZs) were classified into these five groups. All groups contained genes from both monocotyledons and dicotyledons, indicating that the emergence of JAZ genes predates the differentiation of monocotyledons and dicotyledons. Both segmental and tandem duplications contributed greatly to this gene family’s expansion in sunflower, especially in Group II. Moreover, the expression profiles of HaJAZ genes under normal conditions, hormone treatments or abiotic stresses were analyzed based on RNA-seq data. HaJAZ2 may be undergoing pseudogenization as a nonfunctional gene because it was not expressed in any tissue. Many HaJAZ genes in roots upregulated their expression when involved in responding to exogenous hormones, especially methyl-jasmonate. The abiotic stress treatments of sunflower showed that HaJAZ5, HaJAZ15, HaJAZ17, HaJAZ20, and HaJAZ21 tend to be sensitive to certain abiotic stresses. HaJAZs from different groups may share similar functions but also exercise their unique functions when responding to abiotic stresses. We speculated that this gene family was conserved in sequence but varied in its expression among duplicated HaJAZ genes, which implies that they may confer neofunctionalization in the adaptation to abiotic stresses; this work provides insight into the resistance of sunflowers and their adaptation to diverse environmental conditions.

“…The COL family genes contain two conserved elements: the N-terminal BBX (B-box) domain, which consists of four cysteines with a specific structure of (C-X 2 -C-X 16 -C-X 2 -C); and the C-terminal CCT (CONSTANS, CO-like, and TIMING of CAB1) domain [25,26]. Since the discovery of the first COL gene in Arabidopsis [27], numerous members of the COL gene family have been identified in various plant species, including 12 in grapevine (Vitis vinifera) [28], 13 in lotus (Nelumbo nucifera) [29], 14 in Populus [30], 15 in petunia (Petunia axillaris) [31], 16 in rice (Oryza sativa) [32], 17 in Arabidopsis [20], 19 in maize (Zea mays) [33], 22 in sunflower (Helianthus annuus) [34], 25 in banana (Musa acuminata) [35], 26 in soybean (Glycine max) [36], and 42 in cotton (Gossypium hirsutum) [37].…”

The orchid is one of the most distinctive and highly valued flowering plants. Nevertheless, the CONSTANS-like (COL) gene family plays significant roles in the control of flowering, and its functions in Orchidaceae have been minimally explored. This research identified 68 potential COL genes within seven orchids’ complete genome, divided into three groups (groups I, II, and III) via a phylogenetic tree. The modeled three-dimensional structure and the conserved domains exhibited a high degree of similarity among the orchid COL proteins. The selection pressure analysis showed that all orchid COLs suffered a strong purifying selection. Furthermore, the orchid COL genes exhibited functional and structural heterogeneity in terms of collinearity, gene structure, cis-acting elements within their promoters, and expression patterns. Moreover, we identified 50 genes in orchids with a homology to those involved in the COL transcriptional regulatory network in Arabidopsis. Additionally, the first overexpression of CsiCOL05 and CsiCOL09 in Cymbidium sinense protoplasts suggests that they may antagonize the regulation of flowering time and gynostemium development. Our study will undoubtedly provide new resources, ideas, and values for the modern breeding of orchids and other plants.
