“…It was closely related to the negative regulators of leaf senescence, AtWRKY54 and AtWRKY70, which increase their expression during the progression of senescence in leaves and petals and more distantly related to the positive regulator of wheat TaWRKY40-D. Thus, PhWRKY063 may function as a negative regulator of senescence in P. hybrida (Ülker et al 2007;Besseau et al 2012;Zhao et al 2020) (Fig. 6 and Table 3).…”

“…PhWRKY070 was included into group VI (WRKY III subfamily) and related to the negative regulators AtWRKY54 and AtWRKY70 and more distantly with the positive regulator TaWRKY40-D (Fig. 6 and Table 3) (Ülker et al 2007;Besseau et al 2012;Zhao et al 2020).

“…Group III contains a single WRKY domain and a C 2 HC-type zinc finger motif (Xie et al 2005;Eulgem and Somssich 2007). Besides senescence, WRKY proteins have been reported to regulate other biological processes, including plant growth and development (Bakshi and Oelmüller 2014;Ding et al 2014;Raineri et al 2016), diverse biotic and abiotic stress responses (Zou et al 2010;Giacomelli et al 2012;Phukan et al 2016;Birkenbihl et al 2018), and hormonal signalling (Jiang et al 2014;Zhao et al 2020).…”

“…Overexpression of two wheat members in Arabidopsis, TaWRKY7 and TaWRKY40-D, positively regulate senescence (Zhang et al 2016b;Zhao et al 2020). Similarly, members of cotton, GhWRKY17, GhWRKY42, and GhWRKY27, promote leaf senescence, whereas GhWRKY91 represses the process when overexpressed in transgenic Arabidopsis lines (Gu et al 2018a;Gu et al 2018b;Gu et al 2019a;Gu et al 2019b).…”

Several families of transcription factors (TFs) control the progression of senescence. Many key TFs belonging to the WRKY family have been described to play crucial roles in the regulation of leaf senescence, mainly in Arabidopsis. However, little is known about senescence-associated WRKY members in floricultural species. Delay of senescence in leaves and petals of Petunia hybrida, a worldwide ornamental crop are highly appreciated traits. In this work, starting from 28 differentially expressed WRKY genes of Arabidopsis during the progression of leaf senescence, we identified the orthologous in P. hybrida and explored the expression profiles of 20 PhWRKY genes during the progression of natural (age-related) leaf and corolla senescence as well as in the corollas of flowers undergoing pollination-induced senescence. Simultaneous visualization showed consistent and similar expression profiles of PhWRKYs during natural leaf and corolla senescence, although weak expression changes were observed during pollination-induced senescence. Comparable expression trends between PhWRKYs and the corresponding genes of Arabidopsis were observed during leaf senescence, although more divergences were found in petals of pollinated petunia flowers. Integration of expression data with phylogenetics, conserved motif and cis-regulatory element analyses were used to establish a list of solid candidates that could regulate more than one senescence process. Our results suggest that several members of the WRKY family of TFs are tightly linked to the regulation of senescence in P. hybrida.

“…The detached leaves of TaWRKY40-D VIGS (virusinduced gene silencing) wheat plants showed a green phenotype, while the Arabidopsis plants overexpressing TaWRKY40-D showed premature leaf senescence after JA and ABA treatment. Therefore, TaWRKY40-D may positively regulate leaf senescence by changing the biosynthesis and signal transduction of JA and ABA pathway genes [23]. The Arabidopsis strains overexpressing the TaWRKY142 gene are signi cantly more resistant to the fungal pathogen Colletotrichum, and this increased resistance is due to the increased expression of the JA signal marker gene AtPDF1.2 [24].…”

Backgrounds: Wheat (Triticum aestivum L.) is one of the most important food crops in the world. It faces various abiotic stresses during its growth. Drought is one of the main factors limiting the growth and development of wheat. Severe drought stress will Lead to a decline in wheat production. Cytoplasmic glyceraldehyde-3-phosphate dehydrogenase (GAPC) is an important member of the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) family, which is widely present in plant cytoplasm. Plants play an important role in the process of primary metabolism and stress resistance.Result: In this study, a comparative transcriptomic analysis of the TaGAPCs-RNAi strain of Changwu 134 and the wild-type wheat seedlings of Changwu 134 under natural drought conditions was carried out. A total of 30067 differentially expressed genes were screened in RNAi strains and wild-type strains, of which 19,959 genes were up-regulated in RNAi strains and 10,108 genes were down-regulated in transcription. GO analysis shows that differential genes are mainly enriched in biological regulation, cellular processes, metabolic processes, and responses to stimuli. KEGG analysis showed that the differential genes were mainly concentrated in the biosynthesis of phenylpropane, plant hormone signal transduction and flavonoid biosynthesis pathways. By analyzing the expression levels of differential transcription factors, the significantly down-regulated transcription factor WRKY family member TaWRKY2 / 22/28/29/33/40/47/52 in wheat was screened out. The TaWRKY28/33/40/47 gene silencing line was successfully obtained using the barley stripe mosaic virus (BSMV-VIGS) technology. The plants with TaWRKY28/33/40/47 gene silenced were subjected to natural drought treatment, and physiological and biochemical index tests were carried out. The results showed that the growth status of gene-silenced plants was worse than that of wild-type plants, and the relative water content and chlorophyll content decreased. The content of MDA, H2O2 and superoxide anion increases, the activity of antioxidant enzymes (SOD, POD, CAT) decreases, and the content of proline decreases. Conclusion: The results showed that TaGAPCs regulates the expression of some TaWRKYs transcription factors, activates antioxidant pathways, enhances tolerance of wheat to drought stress.
