Through complex networks of signaling interactions, phytohormones regulate growth, development, reproduction and responses to biotic and abiotic stress. Comprehensive metabolomic approaches, seeking to quantify changes in vast numbers of plant metabolites, may ultimately clarify these complex signaling interactions and consequently explain pleiotropic effects on plant metabolism. Synergistic an...

Capillary electrophoresis (CE) coupled with mass spectrometry (MS) or tandem mass spectrometry (MS/MS) is reported as an alternative and potentially useful method for the simultaneous analysis of various classes of phytohormones with diversified structures, including indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), abscisic acid (ABA), gibberellic acid (GA), zeatin (Z), N-benzyladenine ...

BACKGROUND Although numerous studies have used wastewater as substitutes to cultivate microalgae, most of them obtained weaker algal viability than standard media. Some studies demonstrated a promotion of phytohormones on algal growth in standard media. For exploiting a strategy to improve algal biomass accumulation in effluent from anaerobic digestion of kitchen waste (ADE-KW), the agricultura...

Phytohormones have been acknowledged as an eco-friendly and alternative source for plant growth promotion abiotic stress tolerance. Heavy metal has attained considerable attention worldwide because of its serious effects. Globally, it is a major cause crop yield loss. Soybean important legume that continuously faces environmental stress, such heavy stress. The application regulators, phytohormo...

Beans are one of the most important crops in Brazil but still have a low yield. The use technologies such as application biostimulants can provide greater yield for crop. Thus, work aimed to evaluate effect using Azospirillum brasilense and phytohormones on Jalo Precoce beans. experiment was carried out randomized blocks with nine treatments four replications. consisted control, Stimulate (comp...

In this paper we investigated the effect of some phytohormones on the production of flavonoids in cell suspension cultures of Digitalis lanata. There were used two cell lines and different combinations and concentrations of phytohormones. The highest flavonoids amounts were obtained after 14 days of treatment. Among the tested combinations, the highest yield of flavonoids, 7.58 mg/g d.w. (dry w...

Seed and fruit development are intimately related processes controlled by internal signals and environmental cues. The absence of seeds is usually appreciated by consumers and producers because it increases fruit quality and fruit shelf-life. One method to produce seedless fruit is to develop plants able to produce fruits independently from pollination and fertilization of the ovules. The onset...
