The toned mustard WRKY protein can be revealed by regulating the aging process of plants by means of erythromycin.

Recently, Yu Disho, a researcher at the Xishuangdana Tropical Botanical Garden of the Chinese Academy of Sciences, published a research paper entitled Arabidopsis WRKY45 interacts with the DELLA Protein RGL1 to positively regulate age-triggered leaf senescence online.
the study reveals that WRKY protein can regulate plant aging process through erythromycin, which provides a theoretical basis for understanding plant aging process.
aging is a complex biological process regulated by internal and external factors, and it is a stage that most organisms, including plants, must go through in their development.
once plants age, their photosynthmic capacity will be significantly reduced, resulting in a decline in crop yields, so it is important to study the causes of plant aging and seek anti-aging measures in agricultural production.
, although some progress has been made in the study of plant aging, the molecular biology mechanism of plant aging and its signal transd missile network still need to be further studied.
molecular biology team at the Bamana Botanical Garden found that ana mustard WRKY45 is an aging-related gene that is strongly expressed in aging leaves.
physical analysis found that the WRKY45 mutation can slow down the aging process of plants, while its over-expression significantly promotes the process of plant aging.
analysis of gene expression and chromosate immune co-precipitation showed that WRKY45 regulates the aging process of plants by directly regulating the expression of a series of aging-related genes.
further studies have found that WRKY45 interacts with RGL1 proteins to form compounds in the nucleons of cells, and RGL1 is a transcriptional inhibitory protein in the transdulsion pathway of erythromycin signaling.
phetometrine analysis showed that RGL1 over-expression significantly delayed plant aging, while transcription-inhibiting protein pentogenic mutant della in the erythromycin signaling pathway showed accelerated phetometomypes.
GA can significantly promote the aging process of plants through exogenated spraying, while the three mutants gid1agid1bgid1c of erythromycin synthesis mutants ga1 and erythromycin receptomy show significant aging delay.
Through genetic hybridization experiments, it is confirmed that the dedicate of early aging in WRKY45 over-expression plants can be partially delayed by RGL1 over-expression, and the in-body experiment and chromosate immunocopitation analysis show that RGL1 can inhibit the direct regulation of WRKY45's downstream target genes.
The study analyzes the important function of WRKY45 in plant aging process, further expounds the role of erythromycin pathway in plant aging process, and confirms that WRKY45 may participate in regulating plant aging process as an important part of erythromycin pathway and age pathway.
Ligang, an associate researcher at the Botanical Garden in Beijing, is the first author of the paper, and Yu Di is the author of the paper's newsletter.
the research was funded by the National Natural Science Foundation of China, the National Key Research and Development Program, the Chinese Academy of Sciences Youth Innovation Promotion Association, the Chinese Academy of Sciences", "The Light of the West" and the Yunnan Province "Innovation Research Team".
