“…Many studies have shown that WD motifs serve as a scaffold for protein-protein interaction, allowing WDR proteins to form multiple protein complexes with other proteins (van Nocker and Ludwig 2003;Jain and Pandey 2018;Feng et al 2019). For example, TTG1 interacts with R2R3 MYB and bHLH proteins to form MBW activator complexes in regulating cell fate determination and anthocynin biosynthesis (Schiefelbein 2003;Pesch and Hülskamp 2004;Ramsay and Glover 2005;Wang and Chen 2014), even though TTG1 may not be required for the activation of downstream genes of the complexes (Wang et al 2010); whereas the TPL (TOP-LESS)/TPR (TOPLESS-RELATED) co-repressors interact with different types of proteins to repress gene expression (Collins et al 2019).…”

“…WDR proteins are characterized by the presence of tandemly repeated WD40 motifs, ∼40-amino acid stretches typically ending in W (Trp)-D (Asp) (Neer et al 1994). WDR proteins are a superfamily of regulatory proteins found in all eukaryotic cells, with more than 200 members in plants and nearly 350 in human (van Nocker and Ludwig 2003;Ouyang et al 2012;Jain and Pandey 2018;Feng et al 2019). In addition, a few WDR proteins have also been identified in prokaryotes (Janda et al 1996;Jain and Pandey 2018).…”

WDR proteins in plants regulate multiple aspects of plant growth and development, as well as plant responses to environmental stimuli. Here, we report the identification of AIW1 (ABA-induced WD40repeat 1) and AIW2 as novel regulators of salt responses in Arabidopsis. RT-PCR results show that the expression of AIW1 and AIW2 were induced by ABA. Transfection assays in protoplasts show that AIW1 and AIW2 were nucleus proteins and functioned as transcription repressors. When overexpressed in Arabidopsis, AIW1 promoted root elongation, and reduced seedlings sensitivity to ABA. On the other hand, aiw1 aiw2 double mutants showed an increased sensitivity to ABA in seed germination assays. In addition, salt tolerance was reduced in the 35S:AIW1 transgenic plants in root elongation assays. Taken together, our results suggest that AIW1 and AIW2 are ABA-induced plant specific WD40 repeat-containing transcription repressors, and AIW1 and AIW2 function redundantly to regulate ABA and salt responses in Arabidopsis.

“…The WD40 TF typically contains 4-16 tandem repeat WD motifs that form a scaffold to regulate the assembly and binding of multiple protein complexes involved in plant growth and development [76,77]. A total of 54 putative WD40 genes were differentially expressed between the red-fleshed and white-fleshed peach fruits at five developmental stages [78]. In blueberries, high MYB-bHLH-WD40 expression correlated positively with anthocyanin accumulation and color development [79].…”

Carotenoids are the main pigments in watermelon (Citrullus lanatus L.) fruit and contribute to its aesthetic and nutritional value. Phytoene synthase (PSY) is reported to be the first rate-limiting enzyme in carotenogenesis and controls the carotenoid flux. This study aimed to identify PSY genes responsible for carotenoid biosynthesis in the red-fleshed watermelon cultivar LSW-177. The PSY gene members ClPSY1, ClPSY2 and ClPSY3 were characterized and their catalytic activities were displayed in the heterologous complementation assay. The transcript levels of ClPSY genes at the different developmental stages of LSW-177 fruit and the promoter sequence of ClPSY1 were also analyzed. Transcription factors involved in regulating the ClPSY1 expression were scanned with previous RNA-seq data of the different stages during fruit ripening. Results showed that the PSY proteins from watermelon LSW-177 contained the conserved PSY domains and exhibited the ability to condense GGPP into phytoene in E. coli. ClPSY1 is the dominant carotenogenic gene during fruit ripening; and can be induced by light and hormones. Furthermore, Cla013914 and Cla007950 that, respectively encode the transcription factors WD40-like protein and bZIP, likely upregulate ClPSY1 during fruit ripening. In conclusion, ClPSY1 play a dominant role in carotenoid biosynthesis during watermelon fruit ripening and is regulated by complex light and hormone-responsive networks.

“…WD40 protein acts as an adaptor in many protein complexes or protein-DNA complexes (Pesch et al, 2015). It has been identified in plants, humans, and prokaryotes (Hu et al, 2011;Zou et al, 2016;Feng et al, 2019). A total of 743 WD40 proteins are identified in the wheat genome, which is divided into 5 clusters and 11 subfamilies (Hu et al, 2018).…”

The WD40 transcription factor family is a superfamily found in eukaryotes and implicated in regulating growth and development. In this study, 167 WD40 family genes are identified in the Ginkgo biloba genome. They are divided into 5 clusters and 16 subfamilies based on the difference analysis of a phylogenetic tree and domain structures. The distribution of WD40 genes in chromosomes, gene structures, and motifs is analyzed. Promoter analysis shows that five GbWD40 gene promoters contain the MYB binding site participating in the regulation of flavonoid metabolism, suggesting that these five genes may participate in the regulation of flavonoid synthesis in G. biloba. The correlation analysis is carried out based on FPKM value of WD40 gene and flavonoid content in 8 tissues of G. biloba. Six GbWD40 genes that may participate in flavonoid metabolism are screened. The biological functions of the WD40 family genes in G. biloba are systematically analyzed, providing a foundation for further elucidating their regulatory mechanisms. A number of WD40 candidate genes involved in the biosynthesis and metabolism of G. biloba also predicted. This study presents an important basis and direction for conducting further research on the regulatory network of flavonoid synthesis and metabolism.
