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

New 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.

American 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.
