The efficiency of integrated microbial biotechnologies for obtaining several practically valuable metabolites in one technological process is determined both by the maximum concentration these substances and their properties. This especially true secondary metabolites, composition properties which vary depending on cultivation conditions producer. Aim. To research effect tryptophan (a precursor...

It is widely known that numerous adaptive responses of drought-stressed plants are stimulated by chemical messengers known as phytohormones. Jasmonic acid (JA) is one such phytohormone. But there are very few reports revealing its direct implication in drought related responses or its cross-talk with other phytohormones. In this study, we compared the morpho-physiological traits and the root pr...

drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...

Angiosperms, especially Arabidopsis and rice, have long been at the center of plant research. However, technological advances in sequencing led to a dramatic increase genome transcriptome data availability across land plants and, more recently, among green algae. These allowed for an in-depth study evolution different protein families – including those involved metabolism signaling phytohormone...

The central vasculature of plant roots is protected by a hydrophobic ring of endodermal cells that are enclosed by lamellae of suberin. Barberon et al. demonstrate that endodermal suberization plasticity facilitates ion homeostasis, with antithetical regulation of suberin deposition and degradation by the phytohormones abscisic acid and ethylene.
