Ceras foliares epicuticulares de espécies congêneres da mata e do cerrado Foliar epicuticular waxes of congeneric species from forest and cerrado vegetation

Acta Botânica Brasílica, 1996
Espécies de cerrado e mata foram analisadas quanto à sua composição em ceras foliares epicuticulares e de seus componentes hidrocarbonetos. Observou-se nas espécies de cerrado uma tendência a teores de ceras pouco maiores que os de espécies de mata estacionai semidecídua.

Time‐integrated δ2H in n‐alkanes and carbohydrates from boreal needles reveal intra‐annual physiological and environmental signals

New Phytologist, Volume 246, Issue 2, Page 498-514, April 2025.
Summary Reliable insights from key δ2H bioindicators, n‐alkanes and carbohydrates, are hindered by our limited understanding of isotope fractionation processes related to leaf water and primary assimilates. We addressed this with the first study to investigate time‐integrated intra‐annual δ2H signals of n‐alkanes and carbohydrates in a natural forest ...

Symplastic guard cell connections buffer pressure fluctuations to promote stomatal function in grasses

New Phytologist, Volume 246, Issue 1, Page 192-203, April 2025.
Summary Stomata regulate plant gas exchange via repeated turgor‐driven changes of guard cell shape, thereby adjusting pore apertures. Grasses, which are among the most widespread plant families on the planet, are distinguished by their unique stomatal structure, which is proposed to have significantly contributed to their evolutionary and agricultural ...

Temperature governs the relative contributions of cuticle and stomata to leaf minimum conductance

New Phytologist, Volume 245, Issue 5, Page 1911-1923, March 2025.
Summary During periods of stomatal closure, such as drought, plant leaves continue to lose water at a rate determined by the minimum leaf conductance, gmin. Although gmin varies with temperature, less is known about what drives this variation, including how the pathways of water loss (cuticle or stomata) vary with temperature.

Evidence for within‐species transition between drought response strategies in Nicotiana benthamiana

New Phytologist, Volume 244, Issue 2, Page 464-476, October 2024.
Summary Nicotiana benthamiana is predominantly distributed in arid habitats across northern Australia. However, none of six geographically isolated accessions shows obvious xerophytic morphological features. To investigate how these tender‐looking plants withstand drought, we examined their responses to water deprivation, assessed phenotypic ...
