“…In plant cells, hydrogen sulfide (H 2 S) was formerly considered to be a harmful gaseous molecule; however, this concept has changed as plants utilize H 2 S in various developmental processes [ [70] , [71] , [72] ]. When present in low concentrations, it affects several growth and development characteristics, including germination rates [ 73 ], stomatal regulation [ 74 ], and the development of adventitious roots [ 75 ]. Moreover, H 2 S can cause post-translational modifications to proteins through persulfidation (S-sulfhydration), resulting in altered protein localizations and different functional outcomes.…”

“…Hydrogen sulfide promotes seed germination and alleviates these stresses under various abiotic stresses. These stress responses are also associated with ionic imbalance, osmotic balance, lipid peroxidation, protein alterations, and oxidative damage to macromolecular biomolecules (DNA and proteins) [38]. Exogenous HRW treatment of rice seeds could alleviate the inhibition of salt stress on seed germination and seedling growth.…”

The crop seeds have been a staple food for humans, and seed yield is important for sustaining agriculture development and enhancing human adaptability to food risks. The phenomenon of pre-harvest sprouting (PHS), caused by seed dormancy deficiency, and the phenomenon of low seedling emergence caused by seed deep dormancy, will lead to a reduction in agricultural production. Therefore, it is particularly important to understand the regulation mechanisms of seed dormancy. There are many studies on the regulation of seed dormancy in rice, but there are few studies on the regulation of seed dormancy in other crops, and the research on its mechanism is not thorough enough. In this paper, we comprehensively summarize the regulation mechanisms of cereal seed dormancy, including rice, barley and wheat, discussing the integral mechanism of seed dormancy. This information should provide new insights for developing versatile cultivated lines to improve crop yield and economic benefits.
