Turkish Journal of Botany
Abiotic stress conditions impair plant metabolism partly by inducing the excessive production of reactive oxygen species (ROS). Melatonin, a multifunctional indoleamine, has emerged as an important regulator of plant responses to oxidative stress. This review highlights recent findings on the interactions among phytomelatonin, ROS homeostasis, antioxidant metabolism, photosynthetic protection, stress priming, and abiotic stress tolerance. We discuss how melatonin modulates the antioxidative response under diverse stress conditions and evaluate its effects on photosynthetic performance, ROS signaling, and membrane stability. Special attention is given to priming studies showing that melatonin pretreatment can improve stress tolerance. Emerging evidence from plant tissue culture …

Drought Priming Improves Waterlogging Tolerance In Alfalfa, But Less Effectively Than Waterlogging Priming, Gürkan Demi̇rkol, Ni̇lüfer Kara
Turkish Journal of Botany
Waterlogging severely restricts growth and productivity in alfalfa (Medicago sativa L.), necessitating effective strategies to improve stress tolerance. This study investigated whether drought priming or waterlogging priming could enhance tolerance to subsequent waterlogging stress in the alfalfa cultivar “Bilensoy-80”. Plants were subjected to drought priming, waterlogging priming, or no priming prior to progressive waterlogging stress for 0, 4, 8, 12, 16, and 20 days. Waterlogging priming consistently alleviated growth inhibition, maintained chlorophyll content, and reduced oxidative damage under prolonged stress. Drought priming was associated with partial cross-tolerance, particularly through improved root growth, plant water status, and oxidative stress responses, although …

Water-Driven Reactivation Of Photosystem Ii In Plagiochasma Appendiculatum, Vineet Soni, Upma Bhatt, Yashwant Sompura
Turkish Journal of Botany
Plagiochasma appendiculatum, a desiccation-tolerant liverwort, offers a unique system for unraveling the biophysical dynamics of photosynthetic recovery upon rehydration. This study employed high-resolution chlorophyll a fluorescence (ChlF) kinetics to clarify the sequential reactivation of photosystem II (PSII) during the desiccation-to-rehydration transition. Upon desiccation, the OJIP transient collapsed into a linear trace, indicating complete photochemical arrest and inactivation of PSII reaction centers (RCs). Rehydration triggered a biphasic recovery, including an initial rapid phase (0–30 min) marked by sharp increases in F0 and Fm , indicative of PSII–LHCII supercomplex reassembly and thylakoid membrane restoration, followed by a stabilization phase (30–125 min) wherein …

Turkish Journal of Botany
Documenting species, particularly those that are threatened or endangered, is fundamental to biodiversity conservation. However, many taxa remain scientifically unrecognized, being either undiscovered or unpublished. While some plants can be easily recognized as new species, other identifications are obscured by morphological, taxonomic, and nomenclatural complexity. Detecting cryptic or “hidden” species is therefore essential to understanding biodiversity and plant evolution. Our revisionary studies on Salvia demonstrate that the morphologically complex Salvia caespitosa is not a single species but instead comprises at least four distinct species, three with narrow distributions. This conclusion is supported by integrative evidence from extensive field studies, herbarium …
