Crop traits to improve plant water relations under abiotic stresses
… are involved in the tolerance of environmental stresses that affect agricultural production and threat food security: agricultural drought, soil salinity, and nitrogen management. The challenges and perspectives for increasing crop productivity under these stresses are highlighted and enriched …

Breeding broccoli resilient to multi-abiotic stresses using genome editing
Broccoli cultivars are sensitive to environmental stresses. Dramatic fluctuation in temperature and other weather conditions caused by climate change has negatively affected the growth and development of broccoli and reduced broccoli productivity and quality. Plant senescence is one of the most …

Does root complexity affect the response of maize (Zea mays spp. mays) to abiotic stresses?
… of response that cause plants to tolerate abiotic stresses like drought, high temperature, or low nutrient availability are often not well understood; however, abiotic stresses are some of the most influential factors affecting maize yields. Two of the most relevant stresses faced by …

Role of vegetable grafting in the control of abiotic stresses and effects on yield and quality
… del nesto in presenza di stress di natura abiotica, con ripercussioni positive sulla resa. Le basse temperature rappresentano uno dei principali stress abiotici per il peperone. La variabilità genetica per la tolleranza alle basse temperature è limitata, come anche il numero di …

PLANT TOLERANCE TO DROUGHT: MODULATION OF TRANSCRIPTION FACTORS
… quantities of water are used in agriculture, and abiotic stresses, especially drought and increased salinity, are primary causes of crop loss worldwide. Various approaches may be adopted to consume less water in agriculture, one of them being the development of plants that use less water yet …

Mechanisms Regulating the Response of Arabidopsis thaliana to Heat Stress
Abiotic stresses cause extensive losses to agricultural production worldwide. Acclimation of plants to abiotic stresses is mediated by a complex network of transcription factors and other regulatory genes that control multiple defense and acclimation pathways. Although, previous studies uncovered a …

Identification of common and unique stress responsive genes of Arabidopsis thaliana under different abiotic stress through RNA-Seq meta-analysis
Abiotic stress is a major constraint for crop productivity worldwide. To better understand the common biological mechanisms of abiotic stress responses in plants, we performed meta-analysis of 652 samples of RNA sequencing (RNA-Seq) data from 43 published abiotic stress experiments in Arabidopsis …

Generation of Transgenic <i>Medicago Sativa</i> Overexpressing "<i>Osmotin-Chitinase</i>" Gene Chimera
… confer resistance to different biotic and abiotic stresses. Seed germination of several cultivars of <i>Medicago</i> (<i>M. sativa ssp. sativa, M. sativa ssp. falcata, M. sativa ssp. caerulea, M. truncatula</i>, and <i>M. Rugosa</i>) was tested to determine the cultivars with good …

The role of the BHLH038 transcription factor in the regulation of osmotic and drought stress responses in Arabidopsis thaliana
The most important abiotic stress affecting agriculture worldwide is drought. In order to ensure food supply for the expanding world population two critical tasks must be undertaken; maintenance of crop yield as well as the increase of yield potential. Plants have built up a complex stress response …

Economic Impact Analysis of Marker-Assisted Breeding in Rice
Abiotic stresses such as salinity and phosphorous (P) deficiency are major yield-limiting factors for rice, particularly on marginal lands. Marker-aided backcrossing (MAB), enabled by advances in genomics and molecular mapping in recent years, is said to be a more precise, time-saving, and …

Engineering and deploying FRET-based biosensors to illuminate cellular phytohormone dynamics coordinating environmental stress responses
… the relationship between GA's redistribution and abiotic stresses, including nutrient deficiency, salinity stress, high sugar stress and osmotic stress. I then focused on SA which is best known as a plant defence hormone and is also involved in increasing plant tolerance to several abiotic …

Unindo fisiologia, bioquímica e metabolômica para desvendar respostas aos estresses abióticos da Glycine max e Ricinus communis.
… and silencing in Arabidopsis thaliana against abiotic stresses, and to evaluate the metabolome of soybean seeds against stress thermal. To achieve this objective, the germination of A. thaliana seeds that overexpress and silence the RcGELP gene against water and heat stress will be evaluated, …

SIMPLIFIED TRAIT AND GENE DISCOVERY FOR DROUGHT RESILIENCE IN WHEAT USING EINKORN WHEAT
… threatened by climate-driven biotic and abiotic stresses, particularly drought. Genetic improvement remains the most sustainable strategy for enhancing stress resilience and yield stability; however, gene discovery in bread wheat is complicated by its allohexaploid genome (AABBDD, 2n = 6x …

REGULATING CYTOKININ METABOLISM DURING INFLORESCENCE MERISTEM DEVELOPMENT TO PROMOTE HIGHER RICE PRODUCTIVITY THROUGH CHANGES ON PLANT ARCHITECTURE
… duration, as well as its interaction with other abiotic stresses. Since CKX genes have also been shown to be involved in plant tolerance to various abiotic stresses, we analyzed the germination rates of our different osckx mutants under water-deficit conditions generated using polyethylene glycol …

Characterizing Low Nutrient Stress Resistance in Crop Sunflowers (Helianthus annus)
… has met global food production demands, but abiotic stresses are predicted to decrease crop yield in the context of climate change. In order to prevent losses in crop yield under conditions of increasing environmental stress and to reduce environmental damage from unsustainable farming …
