Soil salinisation is a growing threat to global agriculture, which will reduce Brassicaceae crop yield. We summarised recent research progress of Brassicaceae crop salt tolerant varieties through discussed the molecular mechanism and physiological responses. The review provides abundant data for accelerating the breeding of salt-tolerant Brassicaceae and laid a foundation for understanding the mechanism of salt tolerance of Brassicaceae crops and breeding salt-tolerance varieties.

Suaeda salsa is a typical salt-tolerant plant with significant restorative effects on saline soils. In this study, the transcriptomic sequencing of S. salsa after salt stress and drought stress was used to screen and uncover differentially expressed genes and pathways in response to the results, to gain a preliminary understanding of the response mechanism of S. salsa to salt and drought stress at the molecular level. The findings from this study can help to increase the cultivation of salt-tolerant dominant species to improve saline soils and decrease stress on arable land.

The almost complete recovery in the efficiency of PSII under light conditions suggested that moss (Semibarbula orientalis) can tolerate submergence stress (SS) by avoiding irreversible damage to the photosynthetic apparatus. Light not only pays for photosynthesis but also for repairing photosynthesis machinery. In presence of light, the injured light harveting complexes are re-associated even in SS conditions and manage thylakoid membrane integrity and no. of active reaction centres under SS.

The transcriptomics and metabolomics were combined to reveal the global gene profile and metabolic profile of Lonicera japonica with the different stages of harvest, which will provide basic data for the selection of harvesting stages in the production of L. japonica.

There are genes that first sense and regulate the physiological state of the plant, when plants are exposed to unfavourable growth conditions. We found an RD20 gene in chrysanthemum that has a positive regulatory role in adversity. It has promise for direct use in the production of high quality fruits and crops through genetic engineering or traditional breeding methods.
