“…However, the escalating incidence of abiotic stresses, exacerbated by climate change, poses a significant threat to rice cultivation (Raza et al, 2018). Salinity, in particular, has emerged as a major constraint on rice production worldwide, affecting nearly 950 million hectares of arable land, including 250 million hectares of irrigated land (Raja et al, 2022). Rice, being a salt-sensitive glycophyte, exhibits varying degrees of salt tolerance across different growth stages (Chen et al, 2021;Radha et al, 2023).…”

Salinity, a prominent abiotic stressor, profoundly influences the growth and development of rice plants. In this study, 26 genotypes, accompanied by two control varieties, underwent screening for salinity tolerance at the seedling stage through hydroponics. Analysis of variance unveiled significant variations among genotypes in the recorded traits. Unlike many studies that assess salt tolerance based on individual trait means, our approach utilized membership function values, encapsulating cumulative tolerance across all traits. The identification of highly tolerant and tolerant genotypes in this study suggests their potential for enhancing salt tolerance during the seedling stage in rice through targeted breeding efforts.

Background Seaweeds are a viable bioresource for suffering plants against salt stress, as they abundant in nutrients, hormones, vitamins, secondary metabolites, and many other phytochemicals that sustain plants' growth under both typical and stressful situations. The alleviating capacity of extracts from three brown algae (Sargassum vulgare, Colpomenia sinuosa, and Pandia pavonica) in pea (Pisum sativum L.) was investigated in this study. Methods Pea seeds were primed for 2 h either with seaweed extracts (SWEs) or distilled water. Seeds were then subjected to salinity levels of 0.0, 50, 100, and 150 mM NaCl. On the 21st day, seedlings were harvested for growth, physiological and molecular investigations. Results SWEs helped reduce the adverse effects of salinity on pea, with S. vulgare extract being the most effective. Furthermore, SWEs diminished the effect of NaCl-salinity on germination, growth rate, and pigment content and raised the osmolytes proline and glycine betaine levels. On the molecular level, two low-molecular-weight proteins were newly synthesized by the NaCl treatments and three by priming pea seeds with SWEs. The number of inter-simple sequence repeats (ISSR) markers increased from 20 in the control to 36 in 150 mM NaCl-treated seedlings, including four unique markers. Priming with SWEs triggered more markers than the control, however about ten of the salinity-induced markers were not detected following seed priming before NaCl treatments. By priming with SWEs, seven unique markers were elicited. Conclusion All in all, priming with SWEs alleviated salinity stress on pea seedlings. Salinity-responsive proteins and ISSR markers are produced in response to salt stress and priming with SWEs.
