Research ArticleOpen accessIn the abstractDifferential Response of Chitosan-Pretreated Rice Cultivars at the Seedling Stage to Drought Stress on Growth and Leaf MetabolitesWasinee Pongprayoon, Sataporn Deeying, Sakchai Hongthong et al.The escalating prevalence of drought stress presents a significant obstacle to global rice cultivation, particularly in arid regions affected by climate change-induced water scarcity. Despite extensive research on the efficacy of exogenously applied chitosan in enhancing drought tolerance across various crops, there remains a gap in understanding the differential responses of chitosan-treated rice seedlings among different cultivars and different chitosan … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 20 Dec 2024 · 5,246 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIncreasing Plant Health using Plant Growth Regulator from Rice RhizobacteriaMaimuna Nontji, Ayu K. Parawansa, Saida Saida et al.Plant health is a very important factor in the agriculture system. The presence of plant hormones such as Auxin, gibberellic acid, and siderophores with variation numbers in the plant gives different effects on plant health. Related to the environment rich with rhizobacteria, they have a unique function because rhizobacteria can produce a chemical compound known as Plant Growth Promoting Rhizobacteria … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 3 Jan 2023 · 6,031 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Methyl Jasmonate and Plant Growth Promoting Rhizobacteria (PGPR) on Antioxidant Potential and Metabolomic Profiles of Zingiberaceae RhizomesHenny Lieke Rampe, Hanny Hesky Pontororing, Hanry Jefry Lengkong et al.The rhizomes of Zingiberaceae plants are used as cooking spices, medicines, cosmetics and beverage ingredients. Zingiberaceae rhizomes have the potential to be immunostimulants, antioxidants and immunomodulators. Antioxidants are chemical compounds that bind free oxygen radicals and prevent free radicals from damaging healthy cells. This research aimed to analyze the antioxidant potential and metabolomic compounds of the rhizomes of the Zingiberaceae … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 10 Apr 2026 · 1,311 accessesView PDF Cite
