“…This can be related to the early growth and development of seeds. Rehman et al (2021) reported that osmoprimed seeds had a larger embryonic surface area thereby increasing the availability of nutrients for the developing radicle and increasing the embryo axis during germination compared to control seeds. An increase in α-amylase and β-amylase activity during the early stages of germination is associated to improved root anatomical structure, which then enhances the availability of energy from starch metabolism and stimulates root growth (Farooq et al, 2019).…”

Salinity stress is a form of abiotic stress that threatens the sustainability of agriculture in almost all countries in the world. It has an impact in reducing plant productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable crop that has high nutritional value, but extensive saline land area can cause red amaranth yields to decline. Osmopriming is a seed priming method in which seeds are immersed in a solution that has a high osmotic potential, such as PEG (polyethylene glycol) in order to increase germination under unfavorable conditions. This study determined the effect of osmopriming on germination, physiological, and root anatomical attributes of red amaranth roots under salinity stress conditions. The research design used a completely randomized design with two types of treatment, namely, osmopriming and salinity stress. Each treatment used three concentrations, seed osmopriming with 0%, 5%, and 10% of PEG and salinity stress of 0 mM, 50 mM, and 100 mM of NaCl. The measured parameters were germination, growth, physiological, and root anatomical characters. Osmopriming of seeds with 10% PEG increased germination as indicated by the germination percentage, time, and rate reaching 95.55%, 1.393 day, and 71.98%/day, respectively. Red amaranth plants that had been osmoprimed with 10% PEG grew faster when exposed to salinity stress. Application of PEG 5% and 10% increased total chlorophyll levels while decreasing proline levels and Ca-oxalate crystal density. Under salinity stress conditions, PEG application improved the root anatomical characters of red amaranth as shown by increased epidermis thickness, cortex thickness, and stele diameter. Priming application with 10% PEG has the potential to increase the tolerance of red amaranth to salinity stress.

Abiotic stresses, such as drought, salinity, and extreme temperatures, limit plant growth and development, reducing crop yields. Therefore, a more comprehensive understanding of the signaling mechanisms and responses of plants to changing environmental conditions is crucial for improving sustainable agricultural productivity. Chemical screening was conducted to find novel small compounds that act as regulators of the abiotic stress signaling pathway using the ABA-inducible transgenic reporter line. Small molecules called stress response regulators (SRRs) were isolated by screening a synthetic library composed of 14,400 small compounds, affecting phenotypes such as seed germination, root growth, and gene expression in response to multiple abiotic stresses. Seeds pretreated with SRR compounds positively affected the germination rate and radicle emergence of Arabidopsis and tomato plants under abiotic stress conditions. The SRR-priming treatment enhanced the transcriptional responses of abiotic stress-responsive genes in response to subsequent salt stress. The isolation of the novel molecules SRR1 and SRR2 will provide a tool to elucidate the complex molecular networks underlying the plant stress-tolerant responses.
