The plant response to high CO2 levels is heritable and orchestrated by DNA methylation

open access: yesNew Phytologist, Volume 238, Issue 6, Page 2427-2439, June 2023., 2023
Summary Plant responses to abiotic environmental challenges are known to have lasting effects on the plant beyond the initial stress exposure. Some of these lasting effects are transgenerational, affecting the next generation. The plant response to elevated carbon dioxide (CO2) levels has been well studied.

Defining the scope for altering rice leaf anatomy to improve photosynthesis: a modelling approach

open access: yesNew Phytologist, Volume 237, Issue 2, Page 441-453, January 2023., 2023
Summary Leaf structure plays an important role in photosynthesis. However, the causal relationship and the quantitative importance of any single structural parameter to the overall photosynthetic performance of a leaf remains open to debate. In this paper, we report on a mechanistic model, eLeaf, which successfully captures rice leaf photosynthetic ...

Trihelix transcription factors GTL1 and DF1 prevent aberrant root hair formation in an excess nutrient condition

open access: yesNew Phytologist, Volume 235, Issue 4, Page 1426-1441, August 2022., 2022
Summary Root hair growth is tuned in response to the environment surrounding plants. While most previous studies focused on the enhancement of root hair growth during nutrient starvation, few studies investigated the root hair response in the presence of excess nutrients.

Quantifying the effect of shade on cuticle morphology and carbon isotopes of sycamores: present and past

open access: yesAmerican Journal of Botany, Volume 108, Issue 12, Page 2435-2451, December 2021., 2021
Abstract Premise Reconstructing the light environment and architecture of the plant canopy from the fossil record requires the use of proxies, such as those derived from cell wall undulation, cell size, and carbon isotopes. All approaches assume that plant taxa will respond predictably to changes in light environments.

A starting guide to root ecology: strengthening ecological concepts and standardising root classification, sampling, processing and trait measurements

open access: yesNew Phytologist, Volume 232, Issue 3, Page 973-1122, November 2021., 2021
Summary In the context of a recent massive increase in research on plant root functions and their impact on the environment, root ecologists currently face many important challenges to keep on generating cutting‐edge, meaningful and integrated knowledge.

Functional understanding of secondary cell wall cellulose synthases in Populus trichocarpa via the Cas9/gRNA‐induced gene knockouts

open access: yesNew Phytologist, Volume 231, Issue 4, Page 1478-1495, August 2021., 2021
Summary Plant cellulose is synthesized by a large plasma membrane‐localized cellulose synthase (CesA) complex. However, an overall functional determination of secondary cell wall (SCW) CesAs is still lacking in trees, especially one based on gene knockouts.

Comportamiento hidráulico, beneficios y limitaciones de la aplicación de un SDGA a una estructura de pavimento flexible

open access: yesInfraestructura Vial, 2012
El enfoque primario en el diseño de estructuras de pavimento flexible ha estado basado en la densidad y en la estabilidad. En los últimos años se ha detectado que estas estructuras son sistemas de drenaje demasiado lentos, permitiendo infiltraciones ...
