Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Photosynthetic activity and protective reactions of mosses in forest ecosystems of the Ukrainian Roztochia under changing ecological conditions

Біологічні студії
Background. The photosynthetic activity of mosses has not been studied sufficiently, in contrast to vascular plants. Taking into account the specifics of the moss gametophyte organization (poikilohydricity, absence of epidermis, stomata, cuticle), it is ...

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

Plant‐Derived Extracellular Vesicles: Biogenesis, Function, and Application in Cancer Immunotherapy

Phytotherapy Research, EarlyView.
This illustration shows the biogenesis pathways of edible and medicinal plant‐derived extracellular vesicles (PDEVs) and their therapeutic effects following uptake in the human body, highlighting their potential for application in cancer immunotherapy. ABSTRACT Plant‐derived extracellular vesicles (PDEVs) are nanoscale, lipid bilayer‐enclosed vesicles ...

Characteristics of gas exchange and chlorophyll fluorescence in red and green leaves of Begonia semperflorens

Biologia Plantarum, 2011
To determine the effects of leaf colour on gas exchange and chlorophyll fluorescence, two genotypes of Begonia semperflorens with green leaves or red leaves were compared.

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Recent insights into α-carboxysome structure, mechanism, and assembly

Journal of Bacteriology
Bacterial microcompartments (BMCs) are pseudo-organelles that sequester metabolic enzymes, intermediates, and/or gases within the bacterial cytosol. One model BMC is the carboxysome (CB).

Molecular and physiological analysis of flag leaf senescence and remobilization of assimilates in bread wheat under terminal drought stress [PDF]

مجله بیوتکنولوژی کشاورزی, 2017
In the physiological study of stem remobilization of assimilates during grain filling, mutant genetic materials are a valuable tool. Two advanced mutant lines of bread wheat (T-67-60 and T-65-7-1) along with their wild type (Tabasi Cv.) were planted at ...
