Nutrient enrichment changes water transport structures of savanna woody plants
(IOP Publishing, 2021-02)
Brazilian savanna is a seasonally dry biome, highly diverse and distributed mainly on nutrient-limited soils. Interactions between water stress and nutrient availability are important evolutionary filters in these environments. ...
Mechanisms of desiccation tolerance in the bromeliad Pitcairnia burchellii Mez: biochemical adjustments and structural changes
(Elsevier B.V., 2017-12-01)
Rocky outcrops represent the diversity center of vascular desiccation tolerant (DT) plants. Vegetation in this environment is exposed to an extended dry season and extreme conditions due to rocky soils and high sun exposure. ...
Efeito da disponibilidade de água no xilema secundário e laticíferos em plantas jovens de seringueira [Hevea brasilienses (Willd. ex A. Juss) Müll. Arg.]
(Universidade Estadual Paulista (Unesp), 2020-01-31)
A anatomia dos tecidos vasculares secundários e das estruturas secretoras, tais como os laticíferos, varia em função de fatores ambientais e genéticos. Restrições na disponibilidade de água para as plantas podem acarretar ...
Influência da fenologia no desenvolvimento e fisiologia das galhas de Eriogallococcus gen. nov. em Pseudobombax grandiflorum (Cav.) A. Robyns (Malvaceae)
(Universidade Federal de Minas GeraisUFMG, 2010-02-26)
One of the important factors in the interactions that ends up in the development of galls is the adjustment of the herbivore life cycle to that of its host plant. This adjustment is especially important when the system ...
Root hydraulic conductivity and adjustments in stomatal conductance: hydraulic strategy in response to salt stress in a halotolerant species
(Oxford University Press, 2015-11)
Recent advances at the molecular level are introducing a new scenario that needs to be integrated into the analysis of plant hydraulic properties. Although it is not yet clear to what extent this scenario alters the current ...

Respostas fisiológicas e estruturais em plantas submetidas a estresse hídrico recorrente em diferentes condições de luz
(Universidade Estadual Paulista (Unesp), 2018-02-28)
As plantas estão expostas à seca extrema e cada vez mais frequente devido aos cenários das mudanças climáticas. A superação dos períodos de estresse hídrico e a rápida recuperação com o retorno da estação chuvosa são ...
