The search for receptors for abscisic acid (ABA), a phytohormone central to the response of plants to biotic and abiotic stress, has been controversial. In this issue, Pandey et al. (2009) report the identification of two membrane proteins from Arabidopsis, GTG1 and GTG2, that bind ABA in vitro and mediate ABA responses in vivo.

Plants have acquired the capacity to grow continuously and adjust their morphology in response to endogenous and external signals, leading to a high architectural plasticity. The dynamic and differential distribution of phytohormones is an essential factor in these developmental changes. Phytohormone perception is a fast but complex process modulating specific developmental reprogramming. In re...

Plant production, soil quality, and a sustainable environment depend on climate change. Drought is multidimensional stressor that seriously affects plant production. The most sensitive to change the invasive goldenrod (Solidago canadensis L.), which has potentially high-value materials can be used develop novel approach controlling its spread. This study aimed evaluate impact of different appli...

Abstract Background Liquid suspension culture efficiently proliferates plant cells and can be applied to ferns because it rapidly increases the fresh weight of gametophytes. This study assessed gametophyte proliferation sporophyte production Pteridium aquilinum var. latiusculum using a method. Results The growth curve linear phase was confirmed between 9 18 days culture, subculture cycle determ...

Background: Applications of bioinoculants for improving crop productivity may be an eco-friendly alternative to chemical fertilizers. Rhizosphere or soil-inhabiting beneficial microbes can enhance plant growth and through direct indirect mechanisms, i.e. , phosphate solubilization, nutrient acquisition, phytohormone production, etc. Objective: This study is based on the hypothesis that diseases...

Water deficit conditions trigger the production of a chemical signal, phytohormone abscisic acid (ABA), which coordinates multiple responses at different temporal and spatial scales. Despite complexity natural drought conditions, modulation ABA signaling could be harnessed to ameliorate performances crops in face increasingly challenging climate conditions. Based on recent studies, increasing s...
