Effect of witch's broom disease on the phenology of Cupuassu [PDF]

, 1999
The cupuassu (Theobroma grandiflorum [Willd. ex Spreng.] Schum.) is expanding rapidly as a fruit crop in Brazilian Amazonia. The principal limiting factor is witch's broom disease, caused by Crinipellis perniciosa (Stahel) Singer, the only economic ...

Elucidating R‐gene‐mediated resistance to wheat dwarf virus in Triticum aestivum genotypes

Annals of Applied Biology, EarlyView.
This study investigates R‐gene‐mediated resistance to wheat dwarf virus (WDV) among different wheat genotypes. Following inoculation with Psammotettix alienus (leafhoppers) and the subsequent appearance of characteristic symptoms such as yellowing and dwarfing, phenotypic responses were evaluated alongside molecular analyses, including quantification ...

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...
