State of the Art of the Molecular Biology of the Interaction between Cocoa and Witches’ Broom Disease: A Systematic Review. Int J Mol Sci 2023; 24:ijms24065684. [PMID: 36982760 PMCID: PMC10057015 DOI: 10.3390/ijms24065684] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 12/02/2022] [Accepted: 12/04/2022] [Indexed: 03/19/2023] Open
Abstract
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.

Identification of a key protein set involved in Moniliophthora perniciosa necrotrophic mycelium and basidiocarp development. Fungal Genet Biol 2021; 157:103635.

Abstract
Moniliophthora perniciosa is a hemibiotrophic fungus that causes witches' broom disease in cacao (Theobroma cacao L.). The biotrophic fungal phase initiates the disease and is characterized by a monokaryotic mycelium, while the necrotrophic phase is characterized by a dikaryotic mycelium and leads to necrosis of infected tissues. A study of the necrotrophic phase was conducted on bran-based solid medium, which is the only medium that enables basidiocarp and basidiospore production. Six different fungal developmental phases were observed according to the mycelium colour or the organ produced: white, yellow, pink, dark pink, primordium and basidiocarp. In this study, we identified notable proteins in each phase, particularly those accumulated prior to basidiocarp formation. Proteins were analysed by proteomics; 2-D gels showed 300-550 spots. Statistically differentially accumulated spots were sequenced by mass spectrometry and 259 proteins were identified and categorized into nine functional classes. Proteins related to energy metabolism, protein folding and morphogenesis that were potentially involved in primordium and basidiocarp formation were identified; these proteins may represent useful candidates for further analysis related to the spread and pathogenesis of this fungus. To the best of our knowledge, this report describes the first proteomic analysis of the developmental phases of Moniliophthora perniciosa.

Moniliophthora perniciosa development: key genes involved in stress-mediated cell wall organization and autophagy. Int J Biol Macromol 2020; 154:1022-1035. [PMID: 32194118 DOI: 10.1016/j.ijbiomac.2020.03.125] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 02/29/2020] [Accepted: 03/13/2020] [Indexed: 12/11/2022]
Abstract
Moniliophthora perniciosa is a basidiomycete responsible for the witches' broom disease in cacao (Theobroma cacao L.). Chitin synthase (CHS), chitinase (CHIT) and autophagy (ATG) genes have been associated to stress response preceding the formation of basidiocarp. An analysis of literature mining, interactomics and gene expression was developed to identify the main proteins related to development, cell wall organization and autophagy in M. perniciosa. TORC2 complex elements were identified and were involved in the response to the nutrient starvation during the fungus development stages preceding the basidiocarp formation. This complex interacted with target proteins related to cell wall synthesis and to polarization and cell division (FKS1, CHS, CDC42, ROM2). Autolysis and autophagy processes were associated to CHIT2, ATG8 and to the TORC1 complex (TOR1 and KOG1), which is central in the upstream signalization of the stress response due to nutrient starvation and growth regulation. Other important elements that participate to steps preceding basidiocarp formation were also identified (KOG1, SSZ1, GDI1, FKS1, CCD10, CKS1, CDC42, RHO1, AVO1, BAG7). Similar gene expression patterns during fungus reproductive structure formation and when treated by rapamycin (a nutritional related-autophagy stress agent) were observed: cell division related-genes were repressed while those related to autolysis/autophagy were overexpressed.

Protein profile and protein interaction network of Moniliophthora perniciosa basidiospores. BMC Microbiol 2016; 16:120. [PMID: 27342316 PMCID: PMC4919874 DOI: 10.1186/s12866-016-0753-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2016] [Accepted: 06/15/2016] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Witches' broom, a disease caused by the basidiomycete Moniliophthora perniciosa, is considered to be the most important disease of the cocoa crop in Bahia, an area in the Brazilian Amazon, and also in the other countries where it is found. M. perniciosa germ tubes may penetrate into the host through intact or natural openings in the cuticle surface, in epidermis cell junctions, at the base of trichomes, or through the stomata. Despite its relevance to the fungal life cycle, basidiospore biology has not been extensively investigated. In this study, our goal was to optimize techniques for producing basidiospores for protein extraction, and to produce the first proteomics analysis map of ungerminated basidiospores. We then presented a protein interaction network by using Ustilago maydis as a model. RESULTS The average pileus area ranged from 17.35 to 211.24 mm(2). The minimum and maximum productivity were 23,200 and 6,666,667 basidiospores per basidiome, respectively. The protein yield in micrograms per million basidiospores were approximately 0.161; 2.307, and 3.582 for germination times of 0, 2, and 4 h after germination, respectively. A total of 178 proteins were identified through mass spectrometry. These proteins were classified according to their molecular function and their involvement in biological processes such as cellular energy production, oxidative metabolism, stress, protein synthesis, and protein folding. Furthermore, to better understand the expression pattern, signaling, and interaction events of spore proteins, we presented an interaction network using orthologous proteins from Ustilago maydis as a model. Most of the orthologous proteins that were identified in this study were not clustered in the network, but several of them play a very important role in hypha development and branching. CONCLUSIONS The quantities of basidiospores 7 × 10(9); 5.2 × 10(8), and 6.7 × 10(8) were sufficient to obtain enough protein mass for the three 2D-PAGE replicates, for the 0, 2, and 4 h-treatments, respectively. The protein extraction method that is based on sedimentation, followed by sonication with SDS-dense buffer, and phenolic extraction, which was utilized in this study, was effective, presenting a satisfactory resolution and reproducibility for M. perniciosa basidiospores. This report constitutes the first comprehensive study of protein expression during the ungerminated stage of the M. perniciosa basidiospore. Identification of the spots observed in the reference gel enabled us to know the main molecular interactions involved in the initial metabolic processes of fungal development.

Abstract
Witches' broom disease (WBD), caused by the hemibiotrophic fungus Moniliophthora perniciosa, is one of the most devastating diseases of Theobroma cacao, the chocolate tree. In contrast to other hemibiotrophic interactions, the WBD biotrophic stage lasts for months and is responsible for the most distinctive symptoms of the disease, which comprise drastic morphological changes in the infected shoots. Here, we used the dual RNA-seq approach to simultaneously assess the transcriptomes of cacao and M. perniciosa during their peculiar biotrophic interaction. Infection with M. perniciosa triggers massive metabolic reprogramming in the diseased tissues. Although apparently vigorous, the infected shoots are energetically expensive structures characterized by the induction of ineffective defense responses and by a clear carbon deprivation signature. Remarkably, the infection culminates in the establishment of a senescence process in the host, which signals the end of the WBD biotrophic stage. We analyzed the pathogen's transcriptome in unprecedented detail and thereby characterized the fungal nutritional and infection strategies during WBD and identified putative virulence effectors. Interestingly, M. perniciosa biotrophic mycelia develop as long-term parasites that orchestrate changes in plant metabolism to increase the availability of soluble nutrients before plant death. Collectively, our results provide unique insight into an intriguing tropical disease and advance our understanding of the development of (hemi)biotrophic plant-pathogen interactions.
