Beneficial Effects of Phosphite in Mediated by Activation of ABA, SA, and JA Biosynthesis and Signaling Pathways.

Phosphite (Phi) has gained attention in agriculture due to its biostimulant effect on crops. This molecule has been found to benefit plant performance by providing protection against pathogens, improving yield and fruit quality as well as nutrient and water use efficiency. It is still unclear how Phi enhances plant growth and protects against multiple stresses.

Enhanced phenylpropanoid metabolism underlies resistance to f. sp. race 4 infection in the cotton cultivar Pima-S6 ( L.).

f. sp. vasinfectum (FOV) race 4 (FOV4) is a highly pathogenic soil-borne fungus responsible for Fusarium wilt in cotton () and represents a continuing threat to cotton production in the southwest states of the United States, including California, New Mexico, and Texas.

Prospects of genetics and breeding for low-phosphate tolerance: an integrated approach from soil to cell.

Improving phosphorus (P) crop nutrition has emerged as a key factor toward achieving a more resilient and sustainable agriculture. P is an essential nutrient for plant development and reproduction, and phosphate (Pi)-based fertilizers represent one of the pillars that sustain food production systems. To meet the global food demand, the challenge for modern agriculture is to increase food production and improve food quality in a sustainable way by significantly optimizing Pi fertilizer use efficiency.

Root-Knot Nematode Resistance in Determined by a Constitutive Defense-Response Transcriptional Program Avoiding a Fitness Penalty.

Cotton ( spp.) is the most important renewable source of natural textile fiber and one of the most cultivated crops around the world. Plant-parasitic nematode infestations, such as the southern Root-Knot Nematode (RKN) , represent a threat to cotton production worldwide.

Genome accessibility dynamics in response to phosphate limitation is controlled by the PHR1 family of transcription factors in .

As phosphorus is one of the most limiting nutrients in many natural and agricultural ecosystems, plants have evolved strategies that cope with its scarcity. Genetic approaches have facilitated the identification of several molecular elements that regulate the phosphate (Pi) starvation response (PSR) of plants, including the master regulator of the transcriptional response to phosphate starvation PHOSPHATE STARVATION RESPONSE1 (PHR1). However, the chromatin modifications underlying the plant transcriptional response to phosphate scarcity remain largely unknown.

Dissection of Root Transcriptional Responses to Low pH, Aluminum Toxicity and Iron Excess Under Pi-Limiting Conditions in Arabidopsis Wild-Type and Seedlings.

Acidic soils constrain plant growth and development in natural and agricultural ecosystems because of the combination of multiple stress factors including high levels of Fe, toxic levels of Al, low phosphate (Pi) availability and proton rhizotoxicity. The transcription factor SENSITIVE TO PROTON RHIZOTOXICITY (STOP1) has been reported to underlie root adaptation to low pH, Al toxicity and low Pi availability by activating the expression of genes involved in organic acid exudation, regulation of pH homeostasis, Al detoxification and root architecture remodeling in . However, the mechanisms by which STOP1 integrates these environmental signals to trigger adaptive responses to variable conditions in acidic soils remain to be unraveled.

MEDIATOR16 orchestrates local and systemic responses to phosphate scarcity in Arabidopsis roots.

Phosphate (P ) is a critical macronutrient for the biochemical and molecular functions of cells. Under phosphate limitation, plants manifest adaptative strategies to increase phosphate scavenging. However, how low phosphate sensing links to the transcriptional machinery remains unknown.

Adaptation to Phosphate Scarcity: Tips from Arabidopsis Roots.

Phosphorus (P) availability is a limiting factor for plant growth and development. Root tip contact with low Pi media triggers diverse changes in the root architecture of Arabidopsis thaliana. The most conspicuous among these modifications is the inhibition of root growth, which is triggered by a shift from an indeterminate to a determinate root growth program.

Malate-dependent Fe accumulation is a critical checkpoint in the root developmental response to low phosphate.

Low phosphate (Pi) availability constrains plant development and seed production in both natural and agricultural ecosystems. When Pi is scarce, modifications of root system architecture (RSA) enhance the soil exploration ability of the plant and lead to an increase in Pi uptake. In , an iron-dependent mechanism reprograms primary root growth in response to low Pi availability.
