Iron is an essential micronutrient required for a wide variety of cellular functions in plant growth and development. Chlorosis the first visible symptom iron-deficient plants. Glutathione (GSH) ascorbic acid (ASC) are multifunctional metabolites playing important roles redox balancing. In this work, it was shown that GSH ASC treatment prevented chlorosis accumulation reactive oxygen species induced by iron deficiency Arabidopsis leaves. deficiency, increased activity heme protein ascorbate...
The natural composition of nutrients present in food is a key factor determining the immune function and stress responses honeybee ( Apis mellifera ). We previously demonstrated that supplement abscisic acid (ABA), component nectar, pollen, honey, increases colony survival overwinter. Here we further explored role ABA vitro -reared larvae exposed to low temperatures. Four-day-old (L4) 25°C for 3 days showed lower rates delayed development compared individuals growing at standard temperature...
Plants respond to iron deprivation by inducing a series of physiological and morphological responses counteract the nutrient deficiency. These include: (i) acidification extracellular medium, (ii) reduction ferric ion (iii) increased transport ferrous inside root cells. This system is present in strategy I plants strictly regulated; at low concentration are induced whereas upon supply they repressed. The mechanisms related with this process has been extensively studied, however, specific...
Many biotic and abiotic stressors impact bees' health, acting as immunosupressors contribute to colony losses. Thus, the importance of studying immune response honey bees is central develop new strategies aiming enhance fitness confront threats affecting them. If a pathogen breaches physical chemical barriers, can protect themselves from infection with cellular humoral responses which represent second line defense. Through series correlative studies we have previously reported that abscisic...
The effects of parasites, pathogens and agrochemical exposure combined with the cold temperatures winter in temperate-climate regions contribute to immunosuppression honey bees. Recently, we demonstrated that abscisic acid (ABA) dietary supplementation increased tolerance Apis mellifera brood low temperatures. Here, study relationship between exposure, ABA supplementation, expression genes involved immune response in-vitro-reared bee larvae. We found induced several immune-associated larvae,...
ABSTRACT In temperate climates, low ambient temperatures in late winter and spring can result cold stress conditions brood areas of weakened honey bee colonies, leading to increased levels developmental interruptions death the brood. Very little is known about physiological molecular mechanisms that regulate responses acute cold-stress. Here, we hypothesized central regulatory pathways mediated by insulin/insulin-like peptide signalling (IIS) adipokinetic hormone (AKH) are linked metabolic...
