São Paulo's citrus industry is the most advanced in the world in terms of productivity, fruit and orange juice quality, research and development, technology transfer and sustainability. The productive strength of this important agribusiness chain in São Paulo results in significant economic, social and environmental values. However, the competitiveness and economic, social and environment…
Despite the progress in understanding the Moniliophthora perniciosa pathogenesis of cacao (Theobroma cacao), there are still many knowledge gaps. The interaction between two non-model organism poses serious experimental restrictions because of their lifestyles and lack of biological resources. Moniliophthora perniciosa can be categorized into biotypes according to the particular host, wit…
The invasion of the main cacao-producing region of Brazil by the basidiomycete Moniliophthora perniciosa (causal agent of the witches' broom disease) caused the collapse of cacao production, a fundamental and unique raw material for the chocolate industry. Moniliophthora perniciosa and M. roreri are the most limiting pathogens for cacao (Theobroma cacao) cultivation in the Americas. Both …
Crop yields rely heavily on nitrogen (N) fertilization, and the growing demand for food and biofuels has led to the indiscriminate increase in the use of nitrogen fertilizers in modern agriculture, causing a negative impact on the environment. Therefore, increasing plant N use efficiency (NUE) is essential for the development of sustainable agriculture. Plant NUE is a complex trait determ…
Background: Providing double-stranded RNA (dsRNA) to insects has been proven to silence target genes, and this approach has emerged as a potential method to control agricultural pests by engineering plants to express insect dsRNAs. A critical step of this technology is the screening of effective target genes essential for insect development and/or survival. The tomato leafminer (Tuta abso…

Sugarcane (Saccharum spp.) is one of the main agricultural crops in the world for the production of sugar and bioethanol. Water stress represents the most limiting abiotic factor in production, highlighting the need to develop more drought-tolerant cultivars. Facing climate change, breeding programs have redirected their strategies towards the development of drought tolerant cultivars, ac…
"Witches' broom" is an important disease that affects cocoa trees (Theobroma cacao), limiting cocoa production. The etiological agent of the disease is the fungus Moniliophthora perniciosa, a basidiomycete with a hemibiotrophic lifestyle. M. perniciosa isolates are capable of colonizing a range of hosts, ranging from species of the genus Theobroma to solanaceae and wild lianas: the isolat…
"Witches' broom" is an important disease that affects cacao (Theobroma cacao) and is caused by the basidiomycete fungus Moniliophtora perniciosa. The fungus is endemic to the Amazon region, and its introduction in southern Bahia led to the collapse of cocoa plantations and caused important economic and social changes in the region. Moniliophtora perniciosa is characterized as a hemibiotro…

"Witche's broom" is the main disease affecting cacao (Theobroma cacao), limiting cocoa production in South America and the Caribbean. The basidiomycete fungus Moniliophthora perniciosa, the etiologic agent of the disease, has a hemibiotropic lifestyle with a long and peculiar biotrophic period, causing the symptoms of swelling and induction of lateral shoots in the infected branches. The …
"Witches' Broom" is a major disease of cacao, limiting cacao production in South America. The basidiomycete Moniliophthora perniciosa, the causal agent, presents a hemibiotrophic lifestyle with a peculiar, extensive biotrophic phase, promoting typical symptoms of hypertrophic growth and proliferation of infected shoots. The tomato (Solanum lycopersicum) cv. 'Micro-Tom' (MT) is a suitable …

Witches' Broom Disease, caused by the hemibiotrophic basidiomycete Moniliophthora perniciosa, is the most significant disease of cacao (Theobroma cacao) in Brazil. Infection occurs through the penetration of germ tubes originating from basidiospores into meristematic tissues. The main symptoms of the disease are the swelling of infected branches and the pronounced induction of lateral sho…
Plant diseases are a major threat to crop yield in agriculture, impacting the food security and the economy. The pathogenic fungus Moniliophthora perniciosa (Mp) is responsible for causing the witches' broom disease (WBD) of cacao (Theobroma cacao), whose seeds are the exclusive raw material for chocolate manufacture, leading to catastrophic cacao yield losses in South America. Mp is a he…
Moniliophthora perniciosa is the causal agent of witches' broom disease (WBD) in Theobroma cacao, the 'chocolate' tree. This pathogen is considered a threat to world cacao production. The M. perniciosa x host interaction is difficult to investigate as such interaction occurs between two non-model organisms. To circumvent such limitations, tomato can be used as a model due to its susceptib…
The witches' broom disease is the main disease that affects cacao (Theobroma cacao), caused by the basidiomycete Moniliophthora perniciosa. Symptoms include stem swelling and excessive axillary shoots production on infected sites. Our research group has shown that the tomato (Solanum lycopersicum) miniature cultivar 'Micro-Tom' ('MT') is a suitable genetic model system to investigate the …
