Role of proteases in the response of plants to drought
(Elsevier, 2021-09-30)
Plants are sessile organisms that, to survive they develop response mechanisms under water deficit conditions. Plant proteases play an essential role in a diversity of biological processes, among them tolerance to drought ...
Drought will not leave your glass empty : low risk of hydraulic failure revealed by long-term drought observations in world’s top wine regions
(2018)
Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure as frequency and intensity of summer drought increase. ...
Contrasting adaptive responses to cope with drought stress and recovery in Cenchrus ciliaris L. and their implications for tissue lignification
(Wiley, 2020-11-12)
Cenchrus ciliaris L. is a widely used species for cattle feed in arid and semi-arid regions due to good forage value and known tolerance to drought conditions. Here, we provide insights to adaptive responses of two contrasting ...
Drought stress tolerance of Prosopis chilensis and Prosopis flexuosa species and their hybrids
(Springer, 2013-02)
Natural hybridization commonly produces individuals with intermediate morphological and genetic characteristics, but their response to environmental stress is still uncertain, with some studies showing that transgressive ...
Spatial Distribution of Droughts in the Titicaca Lake Basin
(Sociedade Brasileira de MeteorologiaPE, 2022-09-26)
The present research has assessed the spatial distribution of drought risk in the Titicaca Lake Basin located in Peruvian territory for a district scale, based on hazard and vulnerability. Drought hazard has been quantified ...
Wood density proxies of adaptive traits linked with resistance to drought in Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)
(Springer, 2014-10)
A comparison of dead and surviving Douglas fir trees following the 2003 drought was made to define proxies of adaptive traits for resistance to drought. Increment cores were sampled from trees from three French regions: ...
What is hot in tree rings? The wood density of surviving Douglas-firs to the 2003 drought and heat wave
(Elsevier, 2008-08)
In a global warming scenario, drought and heat waves like the one that occurred in 2003 in Europe are expected to become more intense and frequent. This extreme climate event strongly affected the hydraulic balance in many ...
Narrow vessels cavitate first during a simulated drought in Eucalyptus camaldulensis
(Wiley, 2021-09-15)
Establishing drying-limits for mortality of different tree species and understanding the anatomical and physiological traits involved is crucial to predict forests' responses to climate change. The xylem of Eucalyptus ...
Fast classification system for drought tolerance in peanut and soybean
(Sociedade Brasileira de Fisiologia Vegetal (SBFV), 2022-09-06)
Drought is one of the major limitations for agriculture.
The direct selection of tolerant genotypes on the fields is time consuming due to the unpredictability of the environmental conditions. Our group use a physiological ...
