“…GARP TFs perform diverse functions in plants, such as nutrient sensing, chloroplast development and circadian clock oscillation. The cis ‑regulatory elements of the promoter regions play important roles in the expression of GARP genes for the environmental signals, such as nutrient stress and abiotic stress [ 40 – 42 ]. As shown in Table S 3 , 246 potential cis -acting elements were identified in the promoter regions of SpGARP genes.…”

“…Salinity stress is one of the major abiotic stresses limiting plant growth and productivity, it also suppresses the growth of S. polyrhiza [ 60 ]. There are many reports of the GARP genes that responded to salt stress, such as AtGLK2/5/8/20/23/26/34/43/46 in A. thaliana [ 11 ], ZeGLK3 in Z. mays [ 43 ], 27 SiGLK genes in S. lycopersicum [ 61 ], and GhGLK55/120 in G. hirsutum [ 40 ]. In our study, we found that the expression of SpGLK25 was downregulated under salt stress, which helps to explain why the salt stress affects N/P uptake, and growth rate in plants [ 60 ].…”

Background GARP transcription factors perform critical roles in plant development and response to environmental stimulus, especially in the phosphorus (P) and nitrogen (N) sensing and uptake. Spirodela polyrhiza (giant duckweed) is widely used for phytoremediation and biomass production due to its rapid growth and efficient N and P removal capacities. However, there has not yet been a comprehensive analysis of the GRAP gene family in S. polyrhiza. Results We conducted a comprehensive study of GRAP superfamily genes in S. polyrhiza. First, we investigated 35 SpGARP genes which have been classified into three groups based on their gene structures, conserved motifs, and phylogenetic relationship. Then, we identified the duplication events, performed the synteny analysis, and calculated the Ka/Ks ratio in these SpGARP genes. The regulatory and co-expression networks of SpGARPs were further constructed using cis-acting element analysis and weighted correlation network analysis (WGCNA). Finally, the expression pattern of SpGARP genes were analyzed using RNA-seq data and qRT-PCR, and several NIGT1 transcription factors were found to be involved in both N and P starvation responses. Conclusions The study provides insight into the evolution and function of GARP superfamily in S. polyrhiza, and lays the foundation for the further functional verification of SpGARP genes.

“…The G2-Like or GLK transcription factor belongs to the Myb transcription factors of the GARP superfamily. It is present in numerous plant species, including Arabidopsis, cotton, maize, and tobacco, and is involved in several stress responses (Liu et al, 2016;Qin et al, 2021;Zhao et al, 2021;Alam et al, 2022). However, to date, no study has reported on these proteins in soybean species.…”

“…Nevertheless, those associated with abiotic stress have received little attention, and only a few published scientific studies are available. Previously, GLK family genes were discovered and studied in the genomes of several plant species, including Arabidopsis (Alam et al, 2022), cotton (Zhao et al, 2021), maize (Liu et al, 2016), tomato (Wang et al, 2022), and tobacco (Qin et al, 2021). However, there have been no report on the GLK gene family in the soybean genome.…”

The Golden 2-Like (G2-like or GLK) transcription factors are essential for plant growth, development, and many stress responses as well as heavy metal stress. However, G2-like regulatory genes have not been studied in soybean. This study identified the genes for 130 G2-Like candidates’ in the genome of Glycine max (soybean). These GLK genes were located on all 20 chromosomes, and several of them were segmentally duplicated. Most GLK family proteins are highly conserved in Arabidopsis and soybean and were classified into five major groups based on phylogenetic analysis. These GmGLK gene promoters share cis-acting elements involved in plant responses to abscisic acid, methyl jasmonate, auxin signaling, low temperature, and biotic and abiotic stresses. RNA-seq expression data revealed that the GLK genes were classified into 12 major groups and differentially expressed in different tissues or organs. The co-expression network complex revealed that the GmGLK genes encode proteins involved in the interaction of genes related to chlorophyll biosynthesis, circadian rhythms, and flowering regulation. Real-time quantitative PCR analysis confirmed the expression profiles of eight GLK genes in response to cadmium (Cd) and copper (Cu) stress, with some GLK genes significantly induced by both Cd and Cu stress treatments, implying a functional role in defense responsiveness. Thus, we present a comprehensive perspective of the GLK genes in soybean and emphasize their important role in crop development and metal ion stresses.

The Golden2-like (GLK) transcription factor family is a significant group of transcription factors in plantae. The currently available studies have shown that GLK transcription factors have been studied mainly in chloroplast growth and development, with fewer studies in abiotic stress regulation. In this study, all tea plant GLK transcription factors were identified for the first time in tea plants, and genome-wide identification, phylogenetic analysis, and thematic characterization were performed to identify 66 GLK transcription factors in tea plants. These genes are categorized into seven groups, and an amino acid sequence comparison analysis is performed. This study revealed that the structure of GLK genes in tea plants is highly conserved and that these genes are distributed across 14 chromosomes. Collinearity analysis revealed 17 pairs of genes with fragment duplications and one pair of genes with tandem duplications, and the analysis of Ka/Ks ratios indicated that most of the genes underwent negative purifying selection. Analysis of promoter cis-elements revealed that the promoters of tea plant GLK genes contain a large number of cis-acting elements related to phytohormones and stress tolerance. In addition, a large number of genes contain LTR elements, suggesting that tea plant GLK genes are involved in low-temperature stress. qRT‒PCR analysis revealed that the expression of CsGLK17, CsGLK38, CsGLK54, CsGLK11 and CsGLK60 significantly increased and that the expression of CsGLK7 and CsGLK13 decreased in response to low-temperature induction. Taken together, the results of the transcription profile analysis suggested that CsGLK54 may play an important regulatory role under low-temperature stress. The subcellular localization of CsGLK54 was in the nucleus. Furthermore, CsGLK54 positively regulated the transcription levels of the NbPOD and NbSOD genes under low-temperature stress, which led to an increase in POD and SOD enzyme activities and a decrease in MDA content. These findings provide valuable insights into the regulatory mechanism of low-temperature stress in tea plants.
