Summary The superior productivity of C4 plants is achieved via a metabolic C4 cycle which acts as a CO2 pump across mesophyll and bundle sheath (BS) cells and requires an additional input of energy in the form of ATP. The importance of chloroplast NADH dehydrogenase‐like complex (NDH) operating cyclic electron flow (CEF) around Photosystem I (PSI) for ...

Decoupling cell size homeostasis in diatoms from the geometrical constraints of the silica cell wall
Summary Unicellular organisms are known to exert tight control over their cell size. In the case of diatoms, abundant eukaryotic microalgae, two opposing notions are widely accepted. On the one hand, the rigid silica cell wall that forms inside the parental cell is thought to enforce geometrical reduction of the cell size.

Modelo de evaluación técnica del desempeño del mantenimiento de pavimentos flexibles [PDF]
En la gestion de pavimentos es importante evaluar el desempeno de las estrategias de mantenimiento. Esta se realiza mediante modelos tales como HDM-4 a nivel de red. Sin embargo, no siempre se cuenta con calibraciones a nivel de proyecto que permitan precisar los planes de mantenimiento.

Abstract Premise Previous studies have suggested a trade‐off between trichome density (Dt) and stomatal density (Ds) due to shared cell precursors. We clarified how, when, and why this developmental trade‐off may be overcome across species. Methods We derived equations to determine the developmental basis for Dt and Ds in trichome and stomatal indices (

Abstract Premise Leaf epidermal cell morphology is closely tied to the evolutionary history of plants and their growth environments and is therefore of interest to many plant biologists. However, cell measurement can be time consuming and restrictive with current methods.

Permanent deformation model for pavement condition assessment
For many decades, studies have addressed the development of plastic strains in flexible pavements. Currently, there are models available that allow predicting this type of failure, and it is a common practice to include them in the structural design of ...
