Drought stress (DS) is a serious abiotic and major concern across the globe as its intensity continuously climbing. Therefore, it direly needed to develop new management strategies mitigate adverse effects of DS ensure better crop productivity food security. The use arbuscular mycorrhizal fungi (AMF) has emerged an important approach in recent years improve under conditions. AMF establishes relationship with 80% land plants induces pronounced impacts on plant growth provides protection from stress. significantly reduces development by inducing oxidative stress, disturbing membrane integrity, water relations, nutrient uptake, photosynthetic activity, apparatus, anti-oxidant activities. However, can tolerance against DS. maintains improves contents, efficiency (WUE) therefore, Moreover, also protects apparatus drought-induced efficiency, osmolytes, phenols hormone accumulation, accumulation reactive oxygen species (ROS) increasing activities gene expression which provide imperative understand role grown This review presented different functions responses We have provided detailed picture mechanisms mediated induce drought plants. we identified potential research gaps that must be fulfilled for promising future AMF. Lastly, nitrogen (N) development, however, applied N fertilizers quite low. present information how uptake (NUE)

Melatonin-Induced Protection Against Plant Abiotic Stress: Mechanisms and Prospects

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Июнь 9, 2022

Global warming in this century increases incidences of various abiotic stresses restricting plant growth and productivity posing a severe threat to global food production security. The produces different osmolytes hormones combat the harmful effects these stresses. Melatonin (MT) is hormone that possesses excellent properties improve performance under It associated with improved physiological molecular processes linked seed germination, development, photosynthesis, carbon fixation, defence against other In parallel, MT also increased accumulation multiple osmolytes, sugars endogenous (auxin, gibberellic acid, cytokinins) mediate resistance stress. Stress condition plants often reactive oxygen species. has antioxidant substantially scavenges species by increasing activity enzymatic non-enzymatic antioxidants stress conditions. Moreover, upregulation stress-responsive enzyme genes makes it an stress-inducing molecule. However, produced not sufficient induce tolerance. Therefore, development transgenic biosynthesis could be promising approach enhancing This review, therefore, focuses on possible role induction plants. We further discussed critical as potential for improving addition, we addressed shed light future research directions. review would help readers learn more about changing environment provide new suggestions how knowledge used develop

Mitigation of Salinity-Induced Oxidative Damage, Growth, and Yield Reduction in Fine Rice by Sugarcane Press Mud Application

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Апрель 26, 2022

Salinity stress is one of the major global problems that negatively affect crop growth and productivity. Therefore, ecofriendly sustainable strategies for mitigating salinity in agricultural production food security are highly demandable. Sugarcane press mud (PM) an excellent source organic amendment, role PM not well understood. this study was aimed to investigate how mitigates through regulation rice growth, yield, physiological properties, antioxidant enzyme activities fine grown under different conditions. In study, levels (6 12 dS m-1) with or without 3, 6, 9% SPM, respectively were tested. significantly increased malondialdehyde (MDA, 38%), hydrogen peroxide (H2O2, 74.39%), Na+ (61.5%), electrolyte leakage (40.32%), decreased chlorophyll content (32.64%), leaf water (107.77%), total soluble protein (TSP, 72.28%), free amino acids (FAA, 75.27%). However, these negative effects reversed mainly plants after application. application (9%) remained most effective TSP, FAA, accumulation sugars, proline, K+, activity enzymes, namely, ascorbate peroxidase (APX), catalase (CAT), (POD). Thus, findings suggest a PM-mediated eco-friendly strategy alleviation soil could be useful plant productivity saline soils.
