Witchweed’s Suicidal Germination: Can Slenderleaf Help?

open access: yesAgronomy, 2020
The parasitic plant Striga hermonthica (Delile) Benth. is stimulated to germinate by biomolecules (strigolactones) produced in the roots of host and some non-host plants. Non-hosts induce Striga’s suicidal germination and are therefore used as trap crops.

Effects of irrigated cover crop cultivation period on common bean and soybean yield

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Inhibiting HIF‐1α‐Induced miR‐663b Improves Pulmonary Arterial Hypertension by Reducing Dysfunctions of PASMCs Through Repressing Sirt1‐ZBP1‐Mediated PANoptosis

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 15, August 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) is a progressive disease characterised by vascular remodelling. Inflammatory responses and oxidative stress have been shown to contribute to its progression. This study investigated the effects of a novel HIF‐1α‐miR‐663b axis on pulmonary arterial smooth muscle inflammation, oxidative stress and apoptosis ...
