Abstract Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage P in soil. Root hair elongation particularly important since immobile. Here we report that auxin plays a critical role promoting root growth Arabidopsis response low external P. Mutants disrupting synthesis ( taa1 ) and transport aux1 attenuate the response. Conversely, targeting AUX1 expression lateral cap epidermal cells rescues this . Hence from apex differentiation zone...

Auxin represents a key signal in plants, regulating almost every aspect of their growth and development. Major breakthroughs have been made dissecting the molecular basis auxin transport, perception, response. In contrast, how plants control metabolism homeostasis major form indole-3-acetic acid (IAA), remains unclear. this paper, we initially describe function Arabidopsis thaliana gene DIOXYGENASE FOR AUXIN OXIDATION 1 (AtDAO1). Transcriptional translational reporter lines revealed that...

Significance Auxin is a key hormone regulating plant growth and development. We combine experiments mathematical modeling to reveal how auxin levels are maintained via feedback regulation of genes encoding metabolic enzymes. describe oxidation transcriptional control Arabidopsis thaliana gene DIOXYGENASE FOR AUXIN OXIDATION 1 ( AtDAO1 ) expression important at low normal concentrations. In contrast, higher lead increased Gretchen Hagen3 conjugation. Integrating this understanding into...

Salicylic acid (SA) is a plant growth regulator known to take part in defense responses against different types of stresses, including salt stress. In this study, the role foliar applied SA improving berseem variety ‘Anmol’ under stress was examined. Plants were sown plastic pots sand. treated with concentrations salinity (0, 60 mM and 120 NaCl) salicylic 100 mg L-1 150 L-1) as spray. Salinity significantly reduced root shoot fresh dry weight, length, photosynthetic pigments Chl. a, b, a/b,...

Abstract Tropical rainforest soils, or latosols, are distinguished by their low pH and fertility. In orchards, co-cultivating grass has become popular as a way to improve soil quality boost fruit production. Nevertheless, insufficient information is currently available about the response of microbial communities in tropical orchards co-cultivation. Therefore, present research investigates effect cultivation on properties diversity guava ( Psidium guajava L. cv Pearl) latosol orchards. Two...

The increased concentration of lead (Pb) in soils is a serious threat to human beings and plants all over the world. Salinity stress also major issue across globe, which limits crop productivity. use allelochemicals has become an effective strategy mitigate toxic effects abiotic stresses. Sorghum important grown it possesses appreciably allelopathic potential. Therefore, this study was planned determine impacts sorghum water extract (SWE) on improving maize growth under Pb salinity stress....

The utilization of cuttings remains a prevalent method for vegetative propagation in various plant species. Synthetic rooting hormones have conventionally been employed to enhance the process; however, their high cost and potential environmental risks necessitated exploration natural alternative compounds. In this study, efficacy extracts (pure honey, aloe extract, willow moringa cinnamon powder) synthetic auxin derivatives (indole-3-butyric acid α-naphthaleneacetic acid) at concentration...
