Unraveling the dangerous duet between cancer cell plasticity and drug resistance

open access: yesComputational and Systems Oncology, Volume 3, Issue 3, September 2023., 2023
Abstract Cancer cell plasticity is the ability of tumor cells to switch phenotypes and is one of the predominant requisites of cancer cells capable of undergoing metastasis. Cancer cell plasticity is also recognized as one of the major contributors to intratumoral heterogeneity, a critical factor underlying the progression of malignant tumors, which is

Investigating the impacts of biochar on water fluxes in a rice experiment in the dry corridor of Central America, Costa Rica

open access: yesHydrological Processes, Volume 36, Issue 12, December 2022., 2022
How does biochar impact soil water storage? After adding biochar to an upland rice field in Costa Rica, we observed a shift in the soil water retention curves, indicating that rice plants had 2%–7% more water available. The isotopic composition of plant water did not vary with biochar, indicating rice plants likely consumed similar water.

FLOWERING REPRESSOR AAA+ ATPase 1 is a novel regulator of perennial flowering in Arabis alpina

open access: yesNew Phytologist, Volume 236, Issue 2, Page 729-744, October 2022., 2022
Summary Arabis alpina is a polycarpic perennial, in which PERPETUAL FLOWERING1 (PEP1) regulates flowering and perennial traits in a vernalization‐dependent manner. Mutagenesis screens of the pep1 mutant established the role of other flowering time regulators in PEP1‐parallel pathways.
