Salt-resistant plants: SES1, a sensitive mutant of amoeba salt, is the "behind-the-scenes pusher" of the endosome.

In salinized soil, why are some plants salt-resistant and others not? The internal netting becomes the key factor of salt resistance in plants, but how does the endeal mesh play a role? For a long time, the scientific community has been undecided.
, the international journal Plant Physiology recently published online by Shandong Agricultural University School of Life Sciences Professor Zheng Chengchao and Associate Professor Jin Guang's team of the latest results, the study found that the sensitive mutant SES1 is the "behind-the-scenes pusher" of the internal texture network, pushing "salt-resistant plants" to become salt-resistant plants.
soil salinization seriously affects plant growth, and unfortunately about 20 per cent of the world's arable land and nearly half of its irrigated land are affected by salt stress. How
how to use salinized soil to cultivate new salt-resistant crops has become a global problem.
early scientists found that plant endosomes play an important role in the transduction and integration of salt stress signals, but the regulatory relationship between salt stress and endosomeary network stress is still unclear.
The team of Shandong Agricultural University, through forward genetics, screened and identified SES1, a sensitive mutant of aphorina salt, in which the correct folding of proteins was affected, resulting in a large number of misfolded and unfolded proteins concentrated in the endosome.
the misfolding and unfolded proteins have a serious toxic effect on the cells, in order to survive, the cells will activate the endoboxed network coercification response mechanism, in order to reduce the load of protein folding in the endobox, so as to achieve the purpose of reducing stress and protecting cells.
the study, SES1 encodes a molecular companion protein that is positioned in the endoscoscopy network and helps the protein in the endoscoscous net to fold correctly. At
the same time, the internal network stress-sensing protein bZIP17 transcription factor can activate its expression by directly binding the ERSEL shun element in the SES1 promoter.
, SES1 enhances the salt stress resistance of plants by relieving the internal mesh coercion caused by salt damage.
the study provides new insights between plant response to salt stress and internal mesh steady state, and reveals the molecular mechanism of SES1 regulating plant salt resistance, providing important theoretical support for the cultivation of new salt-resistant crops on a larger scale.
