Exogenous Calcium Alleviates the Photosynthetic Inhibition and Oxidative Damage of the Tea Plant under Cold Stress

Horticulturae, Год журнала: 2024, Номер 10(7), С. 666 - 666

Calcium (Ca2+), a second messenger, plays crucial role in plant growth and development as well responding to biotic abiotic stresses. In this work, we explored the of exogenous calcium alleviating cold stress examined relationship between chloride (CaCl2) channel blockers, lanthanum (LaCl3), tea plants under at physiological transcriptional levels. Exogenous Ca2+ partially offsets negative impacts which increased tolerance by significantly raising photochemical efficiency PSII, protective enzyme activities, ABA content, reduced relative electrical conductivity (REC) level malondialdehyde (MDA) concentration. At transcriptome level, enhanced expression key genes involved response pathways. Nevertheless, LaCl3 treatment not only inhibited activities antioxidant enzymes including superoxide dismutase (SOD), peroxidase (POD) catalase (CAT), but also damage. This study aims provide essential insight into stress, better understand molecular mechanisms that facilitate Ca-mediated tolerance.

RETRACTED: Lipidomics, transcription analysis, and hormone profiling unveil the role of CsLOX6 in MeJA biosynthesis during black tea processing

Horticulture Research, Год журнала: 2024, Номер 11(3)

Опубликована: Янв. 30, 2024

Jasmonates, such as jasmonic acid (JA) and methyl jasmonate (MeJA), are crucial aspect of black tea quality. However, lipids species, hormones genes regulated mechanism in the biosynthesis during processing lacking. In this study, we employed lipidomics, hormone metabolism analysis, transcriptome profiling associated with MeJA pathway to investigate these factors. The contents GLs, PLs TAG decreased, accompanied main species reduced, processing. Galactolipids, primarily 34:3/36:6/36:3 DGDG 36:6/36:5/36:4 MGDG, transformed into massive JA processing, decreased SA, MeSA, IAA BA increased zeatin. Additionally, transcriptional activity primary exhibited downregulated trend except for AOS OPR non-primary tend a little high or fluctuation expression. Coordinated expression CsHPL (TEA008699), CsAOS (TEA001041) CsJMT (TEA015791) control flow degradation production. A strong infected reduction key lipoxygenase gene, CsLOX6 (TEA009423), buds significantly reduced level jasmonates downstream genes, MeSA rising ABA declining. We have identified CsLOX6, well established galactolipids, mainly sources by dynamics controlled coordinated expressed (TEA015791). Our findings provide theoretical basis breeding high-quality offer valuable insights improving methods.

Do diverse wheat genotypes unleash their biochemical arsenal differentially to conquer cold stress? A comprehensive study in the Western Himalayas

Physiologia Plantarum, Год журнала: 2023, Номер 175(6)

Abstract Wheat is one of the most important cereal crops in world. Cold stress a major constraint production wheat grown cold climate regions. In this study, we conducted comprehensive assessment tolerance genotypes through field screening, cell membrane stability electrolyte leakage assay and biochemical profiling. A core set comprising 4560 was evaluated for two years (2021–2022), revealing substantial genetic variation tolerance. Most exhibited moderate tolerance, while smaller proportion showed susceptibility to stress. Based on screening data field, mini‐core 350 selected analysis using electrical conductivity assays. Significant differences were observed among genotypes, indicating presence trait. Furthermore, narrowed down 50 diverse candidate that subsequently profiled various biochemicals, including reactive oxygen species (ROS) like lipid peroxidation (MDA) hydrogen peroxide (H 2 0 ), osmoprotectant (proline) enzymatic antioxidants ascorbate peroxidase (APX), superoxide dismutase (SOD), guaiacol (GPX), catalase (CAT). Correlation biochemicals revealed negative associations between (ROS), highlighting their role mitigating oxidative damage under This study enhances our understanding physiological mechanisms underlying wheat. The identified with superior can serve as valuable resources breeding.
