“…The first field of study to use systematic reviews was medicine, starting in the 18th century, and since then systematic reviews have been published in virtually all academic areas, including the biological sciences. Systematic reviews on the behavior of pathogens that affect important plant crops [ 38 , 39 ], as well as on the mitigation of the effects of abiotic factors [ 40 , 41 , 42 ], have contributed to the elucidation of molecular mechanisms, action mechanisms and host responses.…”

Significant scientific advances to elucidate the Moniliophthora perniciosa pathosystem have been achieved in recent years, but the molecular biology of this pathogen-host interaction is still a field with many unanswered questions. In order to present insights at the molecular level, we present the first systematic review on the theme. All told, 1118 studies were extracted from public databases. Of these, 109 were eligible for the review, based on the inclusion and exclusion criteria. The results indicated that understanding the transition from the biotrophic-necrotrophic phase of the fungus is crucial for control of the disease. Proteins with strong biotechnological potential or that can be targets for pathosystem intervention were identified, but studies regarding possible applications are still limited. The studies identified revealed important genes in the M. perniciosa-host interaction and efficient molecular markers in the search for genetic variability and sources of resistance, with Theobroma cacao being the most common host. An arsenal of effectors already identified and not explored in the pathosystem were highlighted. This systematic review contributes to the understanding of the pathosystem at the molecular level, offering new insights and proposing different paths for the development of new strategies to control witches’ broom disease.

“…Cadmium content in leaves was highly correlated with Cd concentration in roots and stems (Figure S3, r > 0.62, P < 0.01), which is explained by the fact that the cacao plant promotes some tolerance strategies such as uptake and transfer of Cd from the root to the shoot ( Oliveira et al., 2022 ). It can be established that cacao is very efficient in translocating Cd to the leaves.…”

“…Variation in cacao Cd accumulation called attention mainly because of international market restrictions for cacao powder and chocolate products with high Cd levels (between 0.10 and 0.80 mg Cd/kg) (The European Commission, 2014). The main factors related to the uptake of soil Cd by the cacao tree were soil pH, soil Cd availability, genotype, geographical location, and agronomic factors such as phosphate fertilizer (Oliveira et al., 2022). Different levels of Cd uptake have been observed among different cacao genotypes, suggesting genetic variation for seed Cd accumulation (Engbersen et al., 2019; Lewis et al., 2018).…”

The cacao tree, Theobroma cacao L., is cultivated in the tropics, mainly in agroforestry systems, to produce seeds, the valuable raw material for the chocolate industry. Thus, the conservation and use of cacao genetic resources in breeding programs to increase yield and improve quality and disease resistance are vital for the global cacao economy. We review three important topics of cacao genetics essential for sustainable production and crop improvement: (1) geographic distribution of wild cacao populations and geographic patterns of their genetic variation in Amazonia; (2) conservation, availability, and use of cacao genetic resources in cultivar development; (3) genetic basis of agronomic traits, available molecular genetic markers, and genomic resources and their application for cacao improvement. We also highlight critical research areas needed to achieve sustainable cacao cultivation.
