Plant hormone crosstalk mediated by humic acids

Abstract Background The reliance on chemical inputs to support high yields is the Achilles’ heel of modern crop production. soil organic matter management as old agriculture itself. Recently, use soluble humic substances plant growth promoters has been brought attention due their effects nutrient uptake and water efficiency. Humic applied directly at low concentrations can trigger different molecular, biochemical, physiological processes in plants. However, how exert this plethoric regulatory action remains unclear. objective study was evaluate changes transcription level genes coding cell receptors, phosphatases, synthesis, function hormones factors. Materials methods After seven days acid treatment, we used RNAseq maize root seedlings. gene compared with control Results Plant kinase receptors phosphatases were regulated by acids. Likewise, related (auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinosteroids, jasmonic salicylic acids) transcript differential levels seedlings well expression a hundred factors modifying signal transduction pathway via alterations subsequent response. Conclusion We showed general mechanism for simultaneously regulating activity several where acids act key hub responses integrating hormonal signalling response pathways.
