Sweet potato is one of the most economically important crops for addressing global food security and climate change issues, especially under conditions extensive agriculture, such as those found in developing countries. However, osmotic stress negatively impacts agronomic economic productivity sweet cultivation by inducing several morphological, physiological, biochemical changes. Plants employ many signaling pathways to respond water modifying their growth patterns, activating antioxidants, accumulating suitable solutes chaperones, making proteins. These metabolic, genetic modifications can be employed best indicators choosing drought-tolerant genotypes. The main objective breeding regions world, affected drought, obtain varieties that combine drought tolerance with high yields. In this regard, study physiological features certain implementation resistance measures. Adapted genotypes selected improved particular growing using tools tolerance-related selection criteria. By regulating genetics way, creation drought-resistant may become cost-effective smallholder farmers.

Published: Aug. 11, 2022

The upregulation of 4-hydroxyphenylpyruvate dioxygenase (HPPD) can protect plants from adverse abiotic stress. Therefore, studying the changes HPPD under stress is extremely valuable. In this study, we employed a rational molecular design strategy to prepare an HPPD-responsive fluorescent probe consisting pyrene fluorophore, linker and benquitrione skeleton recognition moiety that functions via aggregation–disaggregation sensing mechanism. As predicted, exhibited obvious turn-on fluorescence response towards HPPD. addition, in vivo imaging demonstrated excellent capability track Arabidopsis thaliana, dynamic were monitored different degrees high temperature Cadmium (II) ion (Cd2+) This work provides efficient for acquiring noninvasive probe, which could evaluate degree be further exploring resistance mechanism plants.

Plants are exposed to a variety of abiotic and biotic stresses leading increased formation reactive oxygen species (ROS) in plant cells. ROS capable oxidizing proteins, pigments, lipids, nucleic acids, other cell molecules, disrupting their functional activity. During the process evolution, numerous antioxidant systems were formed plants, including enzymes low molecular weight non-enzymatic antioxidants. Antioxidant perform neutralization therefore prevent oxidative damage components. In present review, we focus on biosynthesis antioxidants higher plants cells such as ascorbic acid (vitamin C), glutathione, flavonoids, isoprenoids, carotenoids, tocopherol E), ubiquinone, plastoquinone. Their functioning reactivity with respect individual will be described. This review is also devoted modern genetic engineering methods, which widely used change quantitative qualitative content cultivated plants. These methods allow various lines given properties obtained rather short time. The most successful approaches for transgenesis genome editing enhancement these discussed.

IbNIEL‐mediated degradation of IbNAC087 regulates jasmonic acid‐dependent salt and drought tolerance in sweet potato

Journal of Integrative Plant Biology, Journal Year: 2024, Volume and Issue: 66(2), P. 176 - 195

Published: Jan. 31, 2024

ABSTRACT Sweet potato ( Ipomoea batatas [L.] Lam.) is a crucial staple and bioenergy crop. Its abiotic stress tolerance holds significant importance in fully utilizing marginal lands. Transcriptional processes regulate responses, yet the molecular regulatory mechanisms sweet remain unclear. In this study, NAC (NAM, ATAF1/2, CUC2) transcription factor, IbNAC087 , was identified, which commonly upregulated salt‐ drought‐tolerant germplasms. Overexpression of increased salt drought by increasing jasmonic acid (JA) accumulation activating reactive oxygen species (ROS) scavenging, whereas silencing gene resulted opposite phenotypes. JA‐rich ‐OE (overexpression) plants exhibited more stomatal closure than wild‐type (WT) ‐Ri under NaCl, polyethylene glycol, methyl jasmonate treatments. functions as nuclear transcriptional activator directly activates expression key JA biosynthesis‐related genes lipoxygenase IbLOX ) allene oxide synthase IbAOS ). Moreover, physically interacted with RING‐type E3 ubiquitin ligase NAC087‐INTERACTING LIGASE (IbNIEL), negatively regulating potato.
