Understanding the low photosynthetic rates of sun and shade coffee leaves: bridging the gap on the relative roles of hydraulic, diffusive and biochemical constraints to photosynthesis.

It has long been held that the low photosynthetic rates (A) of coffee leaves are largely associated with diffusive constraints to photosynthesis. However, the relative limitations of the stomata and mesophyll to the overall diffusional constraints to

In high-light-acclimated coffee plants the metabolic machinery is adjusted to avoid oxidative stress rather than to benefit from extra light enhancement in photosynthetic yield.

Coffee (Coffea arabica L.) has been traditionally considered as shade-demanding, although it performs well without shade and even out-yields shaded coffee. Here we investigated how coffee plants adjust their metabolic machinery to varying light suppl

Publikováno v: Plants, Vol 12, Iss 7, p 1479 (2023)

Coffee (Coffea arabica L.) plants have been assorted as highly suitable to growth at elevated [CO2] (eCa), although such suitability is hypothesized to decrease under severe shade. We herein examined how the combination of eCa and contrasting irradia

Exploring leaf hydraulic traits to predict drought tolerance of Eucalyptus clones

Autor: Leonardo A Oliveira, Amanda A Cardoso, Moab T Andrade, Talitha S Pereira, Wagner L Araújo, Gleison A Santos, Fábio M Damatta, Samuel C V Martins

Publikováno v: Tree Physiology. 42:1750-1761

Ongoing changes in climate, and the consequent mortality of natural and cultivated forests across the globe, highlight the urgent need to understand the plant traits associated with greater tolerance to drought. Here, we aimed at assessing key foliar

Impaired auxin signaling increases vein and stomatal density but reduces hydraulic efficiency and ultimately net photosynthesis

Autor: Moab T Andrade, Leonardo A Oliveira, Talitha S Pereira, Amanda A Cardoso, Willian Batista-Silva, Fábio M DaMatta, Agustín Zsögön, Samuel C V Martins

Publikováno v: Journal of Experimental Botany. 73:4147-4156

Auxins are known to regulate xylem development in plants, but their effects on water transport efficiency are poorly known. Here we used tomato plants with the diageotropica mutation (dgt), which has impaired function of a cyclophilin 1 cis–trans i

Elevated [CO2] benefits coffee growth and photosynthetic performance regardless of light availability

Despite being evolved in shaded environments, most coffee (Coffea arabica L.) is cultivated worldwide under sparse shade or at full sunlight. Coffee is ranked as greatly responsive to climate change (CC), and shading has been considered an important
