Formation of Apoplastic Barriers to Radial O₂ Loss in Rice Roots: Effects of Low-O₂ and High-Fe Conditions, and the Roles of Suberin, Glycerol Esters, and Iron Plaques.

Lack of O and high concentrations of iron (Fe) are common in flooded soils where Rice (Oryza sativa L.) is cultivated. We tested the hypothesis that growing in stagnant or high Fe conditions might induce the formation of apoplastic barriers in roots with different properties and chemical compositions.

Giant Angiomyofibroblastoma With a Florid Lipomatous Component: A Report and Review of Diagnostic Considerations.

Angiomyofibroblastoma is a benign, usually small neoplasm typically constituted by spindle-shaped and epithelioid cells in a vascularized, myxoid-fibrous stromal background. It is most often seen in the superficial genitalia of female patients of reproductive age. However, various clinical and histologic features have been reported, including tumors in male patients, malignant transformation, extragenital sites, huge sizes, and a prominent lipomatous pattern.

Identification of molecular and cellular infection response biomarkers associated with anthrax infection through comparative analysis of gene expression data.

Bacillus anthracis, a gram-positive bacillus capable of forming spores, causes anthrax in mammals, including humans, and is recognized as a potential biological weapon agent. The diagnosis of anthrax is challenging due to variable symptoms resulting from exposure and infection severity. Despite the availability of a licensed vaccines, their limited long-term efficacy underscores the inadequacy of current human anthrax vaccines, highlighting the urgent need for next-generation alternatives.

Enhanced CO Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development.

Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO (eCO) will facilitate the identification of nutrient-efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low-nitrogen conditions revealed that eCO drove the development of the endodermal barrier with respect to L-/S-shaped lateral roots (LRs) in rice. Next, we applied metabolome and endodermal-cell-specific RNA sequencing and showed that rice adapts to eCO by spatially recruiting diazotrophs via flavonoid secretion in L-shaped LRs.
