Analysis of phenotypic plasticity in response to water constraints in coffee plants growing under field conditions [PDF]

open access: yes, 2008
In a context of climate change, adaptation of perennial plantations to water constraints becomes a major concern for wood and fruit productivity. Adaptation depends on the level of genetic diversity in breeding and natural populations, as well as their ...

Weak whole‐plant trait coordination in a seasonally dry South American stressful environment

open access: yesEcology and Evolution, 2018
A core question involving both plant physiology and community ecology is whether traits from different organs are coordinated across species, beyond pairwise trait correlations. The strength of within‐community trait coordination has been hypothesized to

Photosynthetic apparatus performance and anatomical modulations of Alcantarea imperialis (Bromeliaceae) exposed to selenium during in vitro growth

open access: yesPhotosynthetica, 2021
Elements not usually included in culture medium formulations, such as selenium (Se), may have beneficial effects on micropropagated plants. We evaluated the effects of Se on the physiological and anatomical responses of Alcantarea imperialis during in ...

Characteristics of C-4 photosynthesis in stems and petioles of C-3 flowering plants [PDF]

open access: yes, 2002
Most plants are known as C-3 plants because the first product of photosynthetic CO2 fixation is a three-carbon compound. C-4 plants, which use an alternative pathway in which the first product is a four-carbon compound, have evolved independently many ...

Lithium alters elicitor-induced H2O2 production in cultured plant cells

open access: yesBiologia Plantarum, 2013
Lithium pollution may seriously influence the metabolic and signalling processes of plants. In the present paper, we investigate the effect of lithium chloride on fungal elicitor-triggered H2O2 generation in Rubia tinctorum L. cell cultures.
