A lipophilic cation protects crops against fungal pathogens by multiple modes of action

The emerging resistance of crop pathogens to fungicides poses a challenge to food security and compels discovery of new antifungal compounds. Here, we show that mono-alkyl lipophilic cations (MALCs) inhibit oxidative phosphorylation by affecting NADH oxidation in the plant pathogens Zymoseptoria tritici, Ustilago maydis and Magnaporthe oryzae.

Cotton crop in changing climate

Cotton is a major cash crop of global significance. It has a peculiar and inherent growth pattern with coinciding physiological growth stages. This study is based upon modelling and simulation for Hisar region. Stage-wise water stress has been quantified for three Bt-cotton cultivars with three sowing dates under both irrigated …

Swollen shoot disease worsening in heart of Ivory Coast cocoa belt

Swollen shoot disease is worsening in the heart of Ivory Coast’s cocoa belt with some plantations seeing a significant drop in production, farmers and exporters said on Tuesday. The viral disease, which typically kills trees within a few years, first appeared a few years ago in southern and western Ivory …

Africa: Cassava Breeding Could Impair Yield By 20%

Ibadan — Breeding African cassava cultivars for improvements such as pest and disease resistance could impair their yield potential, a study suggests. According to UN Food and Agriculture Organization, cassava is a major staple food for over one billion people in 105 countries. In Sub-Saharan Africa and other tropical and …

First report of the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), natural enemies from Africa

The fall armyworm (FAW), Spodoptera frugiperda, is a major pest of maize in North and South America. It was first reported from Africa in 2016 and currently established as a major invasive pest of maize. A survey was conducted to explore for natural enemies of the fall armyworm in Ethiopia, …

Nonsensical choices? Fall armyworm moths choose seemingly best or worst hosts for their larvae, but neonate larvae make their own choices

Selecting optimal host plants is critical for herbivorous insects, such as fall armyworm (Spodoptera frugiperda), an important maize pest in the Americas and Africa. Fall armyworm larvae are presumed to have limited mobility, hence female moths are presumed to be largely responsible for selecting hosts. We addressed host selection by …

Large sub-clonal variation in Phytophthora infestans from recent severe late blight epidemics in India

The population structure of the Phytophthora infestans populations that caused the recent 2013–14 late blight epidemic in eastern India (EI) and northeastern India (NEI) was examined. The data provide new baseline information for populations of P. infestans in India. A migrant European 13_A2 genotype was responsible for the 2013–14 epidemic, …

Dual impact of elevated temperature on plant defence and bacterial virulence in Arabidopsis

Environmental conditions profoundly affect plant disease development; however, the underlying molecular bases are not well understood. Here we show that elevated temperature significantly increases the susceptibility of Arabidopsis to Pseudomonas syringae pv. tomato (Pst) DC3000 independently of the phyB/PIF thermosensing pathway. Instead, elevated temperature promotes translocation of bacterial effector proteins …
