Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide expected rise in the coming years. Therefore, it vital understand physiological, biochemical, molecular, ecological mechanisms associated DS. This review examines recent advances plant responses DS expand our understanding of DS-associated mechanisms. Suboptimal water sources affect growth yields through physical impairments, physiological disturbances, biochemical modifications, molecular adjustments. To control devastating effect plants, important its consequences, mechanisms, agronomic genetic basis sustainable production. In addition responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, mechanical methods (foliar treatments, seed priming, conventional practices). Further, have also presented scope speed breeding platforms helping develop drought-smart future crops. short, recommend incorporating multi-omics, traditional strategies, cultivars achieve 'zero hunger' goal.

Origin, evolution, breeding, and omics of Apiaceae: a family of vegetables and medicinal plants

Horticulture Research, Год журнала: 2022, Номер 9

Опубликована: Янв. 1, 2022

Many of the world's most important vegetables and medicinal crops, including carrot, celery, coriander, fennel, cumin, belong to Apiaceae family. In this review, we summarize complex origins current state research on family, traditional molecular breeding practices, bioactive compounds, applications, nanotechnology, omics research. Numerous markers, regulatory factors, functional genes have been discovered, studied, applied improve vegetable crops in Apiaceae. addition, trends application are also briefly described, mining new metabolites using research, identifying genetic variants associated with agronomic traits by population genetics analysis GWAS, applying transformation, CRISPR-Cas9 gene editing system, nanotechnology. This review provides a reference for basic plants.

Role of Carrot (Daucus carota L.) Storage Roots in Drought Stress Adaptation: Hormonal Regulation and Metabolite Accumulation

Metabolites, Год журнала: 2025, Номер 15(1), С. 56 - 56

Опубликована: Янв. 16, 2025

Background: Drought stress has become one of the biggest concerns in threating growth and yield carrots (Daucus carota L.). Recent studies have shed light on physiological molecular metabolisms response to drought carrot plant; however, tissue-specific responses regulations are still not fully understood. Methods: To answer this curiosity, study investigated interplay among tissues, such as leaves (L); storage roots (SRs); lateral (LRs) under conditions. This revealed that SRs played a crucial role an early perception by upregulating key genes, including DcNCED3 (ABA biosynthesis) DcYUCCA6 (auxin biosynthesis). The abundance osmolytes (proline; GABA) carbohydrates (sucrose; glucose; fructose; mannitol; inositol) was also significantly increased each tissue. In particular, LRs accumulated high levels these metabolites promoted Conclusions: Our findings suggest SR acts central regulator synthesizing ABA auxin, which modulate accumulation LRs. provides new insights into mechanisms tolerance, emphasizing plays improving resistance.

Alterations in Physiological, Biochemical, and Molecular Responses of Impatiens walleriana to Drought by Methyl Jasmonate Foliar Application

Genes, Год журнала: 2023, Номер 14(5), С. 1072 - 1072

Опубликована: Май 12, 2023

Drought stress affects plant growth and development through several mechanisms, including the induction of oxidative stress. To cope with drought, plants have drought tolerance mechanisms at physiological, biochemical, molecular levels. In this study, effects foliar application distilled water methyl jasmonate (MeJA) (5 50 µM) on responses Impatiens walleriana during two regimes (15 5% soil content, SWC) were investigated. The results showed that response depended concentration elicitor intensity. highest chlorophyll carotenoid contents observed SWC in pre-treated µM MeJA, while MeJA did not a significant effect a/b ratio drought-stressed plants. Drought-induced formation hydrogen peroxide malondialdehyde sprayed was significantly reduced leaves pretreated MeJA. lower total polyphenol content antioxidant activity secondary metabolites MeJA-pretreated observed. affected proline enzyme activities (superoxide dismutase, peroxidase, catalase) suffered from drought. expression abscisic acid (ABA) metabolic genes (IwNCED4, IwAAO2, IwABA8ox3) most four analyzed aquaporin (IwPIP1;4, IwPIP2;2, IwPIP2;7, IwTIP4;1), IwPIP1;4 IwPIP2;7 strongly induced study's findings demonstrated significance regulating gene ABA pathway aquaporins, as well considerable alterations I. improved our understanding horticulture plant's physiology field hormones' interaction network general.

Physiological and Molecular Aspects of Two Thymus Species Differently Sensitive to Drought Stress

BioTech, Год журнала: 2022, Номер 11(2), С. 8 - 8

Опубликована: Март 23, 2022

Drought is one of the most important threats to plants and agriculture. Here, effects four drought levels (90%, 55%, 40%, 25% field capacity) on relative water content (RWC), chlorophyll carotenoids levels, mRNA gene expression metabolic enzymes in Thymus vulgaris (as sensitive drought) kotschyanus a drought-tolerant species) were evaluated. The physiological results showed that treatment predominantly affected RWC, chlorophyll, content. analysis demonstrated moderate severe stress had greater histone deacetylase-6 (HDA-6) acetyl-CoA synthetase both species. Pyruvate decarboxylase-1 (PDC-1) was upregulated at high levels. Finally, succinyl CoA ligase not by either Data confirmed able alter specific enzymes. Furthermore, our suggest PDC-1 independent from HDA-6 increased ACS can be due activation new pathways involved carbohydrate production.
