Aegilops umbellulata serve as an important reservoir for novel biotic and abiotic stress tolerance for wheat improvement. However, chromosomal rearrangements and evolutionary trajectory of this species remain to be elucidated. Here, we present a comprehensive investigation into Ae. umbellulata genome by generating a high-quality near telomere-to-telomere genome assembly of PI 554389 and resequencing

Geum japonicum Thunb. var. chinense (G. japonicum) is a cultivated medicinal plant and used as folk medicine, among which tannins are the main active ingredients. In this work, L-proline-lactic acid (Pro:La) as natural deep eutectic solvents (NADESs) was tailored for the total tannins extraction from G. japonicum with the optimal conditions as follows: water content of 29 %, solid-liquid ratio of 27:1

Proceedings of the National Academy of Sciences, Volume 121, Issue 38, September 2024.

Biological and eco-friendly control agents have recently gained more attention due to environmental pollution and weed species' resistance to synthetic herbicides. As allelochemicals, essential oils (EOs) and terpenoid volatile compounds have been considered suitable alternatives to develop environmentally friendly herbicides. This work aimed to evaluate the phytotoxic activity of Artemisia austriaca

In the global search for sustainable and environmentally friendly materials, the efficient utilization of biomass resources has become a hot research topic. Due to the high specific surface area, nanocellulose crystals (CNCs) have attracted considerable attention. However, CNC preparation often requires the separation of lignin and hemicellulose, which wastes resources. In this study, lignin-containing

The primary aim of this effort is to examine how the natural fiber orientation angle affects the lamina's engineering constants, which include the lamina level shear coupling coefficients (ηxy,x and ηxy,y), major Poisson's ratio (νxy), longitudinal and transverse Young's moduli (Ex and Ey), and shear modulus (Gxy). The lamina that is being studied is made of epoxy and natural fiber. Six natural fibers
