Yerba mate is a tree species whose natural distribution occurs in the countries of Argentina, Paraguay, and Brazil, where most of the plantations are concentrated. For the establishment of plantations seedlings are commonly ...
Plant Biochemical Mechanisms for the Maintenance of Oxidative Stress under Control Conditions
(CRC Press - Taylor & Francis Group, 2020)
The presence of O2 in the earth´s atmosphere originated over 2.2 billion years ago as a consequence of the evolution of oxygenic photosynthetic activity by cyanobacteria. After this, several organisms began to evolve a ...

(Wiley Blackwell Publishing, Inc, 2020-02-14)
This study aimed at investigating the physiological responses of Piaractus mesopotamicus exposed to high stocking density and the potential protective role of supplemented diets. Fish were fed with basal, red seaweed ...
Fast weight recovery, metabolic rate adjustment and gene-expression regulation define responses of cold-stressed honey bee brood
(Pergamon-Elsevier Science Ltd, 2021-01)
In temperate climates, low ambient temperatures in late winter and in spring can result in cold stress conditions in brood areas of weakened honey bee colonies, leading to increased levels of developmental interruptions ...
Involvement of jasmonates in responses of sunflower (Helianthus annuus) seedlings to moderate water stress
(Springer, 2017-12)
Jasmonates (JAs), a type of phytohormone, are involved in sensing and signaling of several environmental stresses (biotic and abiotic). Jasmonic acid (JA) has been suggested to function in plant responses to drought, because ...
