The origins of C4 grasslands : integrating evolutionary and ecosystem science

, 2010
The evolution of grasses using C4 photosynthesis and their sudden rise to ecological dominance 3 to 8 million years ago is among the most dramatic examples of biome assembly in the geological record.

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny

, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

A SINGLE CENTRE EXPERIENCE OF LOW C3/C4 LEVELS AND OTHER LABORATORY ASPECTS IN TURKISH CHILDREN WITH IMMUNOGLOBULIN A VASCULITIS

Sabiad
Objective: Immunoglobulin A vasculitis (IgAV) is the most prevalent systemic vasculitis in childhood. This intricate immune-mediated vasculitis affects the small blood vessels in several organ systems.

Metabolic profiles in C3, C3-C4 intermediate, C4-like and C4 species in the genus Flaveria

, 2022
C4 photosynthesis concentrates CO2 around Rubisco in the bundle sheath, favouring carboxylation over oxygenation and decreasing photorespiration. This complex trait evolved independently in over 60 angiosperm lineages.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Soil Nutrients Effects on the Performance of Durum Wheat Inoculated with Entomopathogenic Fungi

Agronomy, 2020
Entomopathogenic fungi (EFs) are widely used as biological control agents. However, some strains of Beauveria bassiana and Metarhizium brunneum can also promote plant growth and increase nutrient uptake.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.
