Cytological Studies on Germinating Teliospores ofHemileia Vastatrix [PDF]

Caryologia, 1965
SUMMARYMeiosis in the teliospores of Hemileia vastatrix is seen to differ from the rust fungi where the basidium is external. The chromosome number is larger than has been reported for most of the Basidiomycetes. The irregularities recorded under natural conditions suggest some disturbance in the important phase in the life cycle of the fungus ...

Climate Change Impacts on Agriculture: A Review of Plant Diseases and Insect Pests in Ethiopia and East Africa, With Adaptation and Mitigation Strategies

Advances in Agriculture, Volume 2025, Issue 1, 2025.
Climate change significantly threatens global agriculture, with East Africa, particularly Ethiopia, being highly vulnerable due to its reliance on rain‐fed farming. This review investigates the effects of climate change on plant diseases and insect pests, underscoring the urgent need for adaptation and mitigation measures. Ethiopia’s observable climate

Antimicrobial Potential of Endophytic Fungal Extracts From the Mangrove Avicennia germinans Against Phytopathogens

International Journal of Agronomy, Volume 2025, Issue 1, 2025.
The prolonged use of synthetic pesticides in agriculture has resulted in the emergence of resistant organisms, high residual levels, and negative impacts on beneficial organisms and human health. These issues highlight the need to explore alternative control strategies based on natural products from ecosystems such as mangroves.

Genomics‐based plant disease resistance prediction using machine learning

Plant Pathology, Volume 73, Issue 9, Page 2298-2309, December 2024.
The potential of machine learning as a complementary tool for predicting the genetic loci contributing to disease resistance in plants. Abstract Plant disease outbreaks continuously challenge food security and sustainability. Traditional chemical methods used to treat diseases have environmental and health concerns, raising the need to enhance inherent

Relationships between landscape context and coffee rust (Hemileia vastatrix), coffee berry borer (Hypothenemus hampei) and the rootknot nematodes Meloidogyne spp. En Costa Rica [PDF]

, 2010
Disease and pest attack intensities are mainly determined at the plot level through interactions between the host, noxious organism, environment and agricultural management (Zadoks and Schein, 1979).

Using local knowledge to reconstruct climate‐mediated changes in disease dynamics and yield—A case study on Arabica coffee in its native range

PLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 935-950, July 2024.
Adapting agriculture to climate change requires an understanding of the long‐term relationship between climate, disease dynamics, and yield. While some countries have monitored major crop diseases for decades or centuries, comparable data is scarce or non‐existent for many countries that are most vulnerable to climate change. For this, a novel approach

Receptor-Like Kinase (RLK) as a candidate gene conferring resistance to Hemileia vastatrix in coffee

Scientia Agricola, 2020
: The biotrophic fungus Hemileia vastatrix causes coffee leaf rust (CLR), one of the most devastating diseases in Coffea arabica . Coffee, like other plants, has developed effective mechanisms to recognize and respond to infections caused by pathogens ...
