Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Genome Re-Sequencing Reveals the Host-Specific Origin of Genetic Variation in Magnaporthe Species

open access: yesFrontiers in Genetics, 2022
Rice blast is caused by Magnaporthe oryzae (M. oryzae), which is considered one of the most serious pathogens of rice around the globe. It causes severe losses owing to its proven capability to disrupt the host resistance.
