Summary: The study identified 90 AsGRAS genes in oat, which are involved in plant growth and development, disease resistance, and stress response. These genes were randomly distributed on 21 chromosomes and showed duplications, indicating the expansion of the GRAS gene family. They were classified into 10 subfamilies based on phylogenetic analysis. The genes were expressed at different stages and under different stresses, suggesting their potential role in promoting growth and stress tolerance in oat.

Summary: The natural populations of East Indian sandalwood (Santalum album L.) have greatly declined due to overexploitation in the past three decades. Santalum album L. seeds have poor germination, hindering nursery seedling production and plantation establishment. This study investigated the effects of hydro- and osmopriming on the germination and seedling performance of Santalum album L. The results showed that osmopriming with 5% PEG solutions for 2 days resulted in the highest germination (79%), which was 42% higher than the control. Longer priming times (6-8 days) had no effect or negatively affected germination and growth. Osmopriming can be recommended as a low-cost technology to enhance seed germination and seedling growth for quality planting material of Santalum album L.

Summary: The new variants of COVID-19 have spread rapidly worldwide, and efforts are being made to find virus-specific antiviral drugs. The main protease of SARS-CoV-2 has been identified as a potential drug target. Apigenin analogues were evaluated for their binding to the main protease of SARS-CoV-2. The results showed that Apigenin 7-glucoside-4'-p-coumarate is the best candidate for inhibiting SARS-CoV-2 M-pro.

Summary: The study investigated the ability of alginates extracted from two Moroccan brown seaweeds and their derivatives to induce phenolic metabolism in tomato seedlings. Elicitation was done by foliar spraying the seaweed alginates on tomato seedlings and evaluating their effects on PAL activity, polyphenol, and lignin production. It was found that low-molecular-weight alginates were more effective in inducing natural defenses in tomato seedlings compared to the alginate polymers. These findings suggest that low-molecular-weight alginates may have potential as a stimulant for plant natural defenses.

Summary: This study investigates the impact of partial acid hydrolysis on the antihyperglycemic activity of a polysaccharide derived from Plantago ciliata seeds. The results demonstrate that the resulting oligosaccharides exhibit significant inhibitory effects on alpha-amylase and alpha-D-glucosidase enzymes and act as non-competitive inhibitors. Additionally, these oligosaccharides show resistance to digestion, suggesting their potential as a natural and healthy drug for reducing blood sugar levels.
