Plastids features and transfer cells occurrence in the phloem of Portulaca mucronata and P. hirsutissima (Portulacaceae)

open access: yesActa Societatis Botanicorum Poloniae, 2014
The species of the Portulacaceae of the Serra do Cipó, State of Minas Gerais, Brasil, were studied. In Portulaca mucronata and P. hirsutissima transfer cells are companion and phloem parenchyma cells; they have the same secondary cell wall features, that

Accelerated remodeling of the mesophyll-bundle sheath interface in the maize C4 cycle mutant leaves

open access: yesScientific Reports, 2022
C4 photosynthesis in the maize leaf involves the exchange of organic acids between mesophyll (M) and the bundle sheath (BS) cells. The transport is mediated by plasmodesmata embedded in the suberized cell wall.

Assessing the Effectiveness of Workers' Selection Exams: The Case of the Bank of Italy

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT High‐stakes exams can be used to rank and select candidates for job openings, and the ability of those selected hinges on the design of the exam. I propose a method to model candidates' performance to assess how effective the exam is at selecting high‐ability candidates.

Regulatory Mechanism of CsMYB1‐CsMYB82/CsbHLH48‑CsCAD4 Model for Resistance Against Colletotrichum gloeosporioides in Camellia sinensis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Anthracnose caused by Colletotrichum gloeosporioides is a major threat to tea cultivation; however, the molecular mechanism underlying different resistance among tea cultivars remains unclear. We identified distinct expression patterns of CsMYB82 between anthracnose‐resistant and susceptible varieties after infection with anthracnose from ...

The genetic regulation of Kranz anatomy in maize

open access: yes, 2016
The C4 photosynthetic pathway acts to concentrate CO2 around the enzyme Ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco), ensuring that it catalyses a carboxylation rather than oxygenation reaction, which in turn suppresses photorespiration. In nearly all cases C4 photosynthesis is underpinned by characteristic Kranz anatomy, with concentric ...

Диференціaція судинної обкладинки та мезофілу у С3 і С4 видів рослин у зв’язку з оптимізацією фотосинтезу

open access: yesФактори експериментальної еволюції організмів, 2015
Aims. The comparative anatomical study of the bundle sheath and mesophyll in C3 and C4 species to determine the changes in leaf anatomy that cause the formation of two-chamber C4 system named Kranz anatomy. Methods.

Acute prefrontal hemodynamic responses to intermittent theta burst stimulation correlate with current depression and episode recurrence: A cross‐sectional study

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Background Mounting evidence has indicated that multiple major depressive disorder (MDD) episodes are correlated with brain morphometric changes that confer an increased recurrence risk. Functional abnormalities underlying this recurrent vulnerability remain underexplored.

Methods of analysis of chloroplast genomes of C3, Kranz type C4 and Single Cell C4 photosynthetic members of Chenopodiaceae

open access: yesPlant Methods, 2020
Background Chloroplast genome information is critical to understanding forms of photosynthesis in the plant kingdom. During the evolutionary process, plants have developed different photosynthetic strategies that are accompanied by complementary ...

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

Climate change‐driven expansion of goosegrass highlights risks to global food production

open access: yesPest Management Science, Volume 82, Issue 7, Page 6494-6508, July 2026.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.
