Lignin Peroxidase (TvLiP): Genetic and Molecular Characterization.

White-rot basidiomycetes are the organisms that decompose lignin most efficiently, and is a promising species for ligninolytic enzyme production. There are several publications on applications for lignin degradation regarding the expression and secretion of laccase and manganese peroxidase (MnP) but no reports on the identification and characterization of lignin peroxidase (LiP), a relevant enzyme for the efficient breakdown of lignin. The object of this study was to identify and partially characterize, for the first time, gDNA, mRNA, and the corresponding lignin peroxidase (TvLiP) protein from strain CCMB561 from the Brazilian semiarid region.

Mycelial development preceding basidioma formation in Moniliophthora perniciosa is associated to chitin, sugar and nutrient metabolism alterations involving autophagy.

We identified and characterized two chitinases, named MpCHIT1 and MpCHIT2, from the fungus Moniliophthora perniciosa - the etiologic agent of witches' broom disease in cacao tree (Theobroma cacao L.) - during its development, mainly in the mycelia phases preceding the basidioma formation. The expression of MpCHIT1 and MpCHIT2, together with MpCHS and MpATG8 (chitin synthase and autophagy genes, respectively), was analyzed during the M.

Transcriptomics and systems biology analysis in identification of specific pathways involved in cacao resistance and susceptibility to witches' broom disease.

This study reports on expression analysis associated with molecular systems biology of cacao-Moniliophthora perniciosa interaction. Gene expression data were obtained for two cacao genotypes (TSH1188, resistant; Catongo, susceptible) challenged or not with the fungus M. perniciosa and collected at three time points through disease.

Use of response surface methodology to examine chitinase regulation in the basidiomycete Moniliophthora perniciosa.

We report here the first analysis of chitinase regulation in Moniliophthora perniciosa, the causal agent of the witches' broom disease of cacao. A multivariate statistical approach was employed to evaluate the effect of several variables, including carbon and nitrogen sources and cultivation time, on M. perniciosa non-secreted (detected in mycelium, i.
