Trail of decryption of molecular research on Botryosphaeriaceae in woody plants

The family Botryosphaeriaceae is species rich and includes pathogens, saprobes and endophytes of economically important agricultural crops and plants. As pathogens, Botryosphaeriaceae species employ evolving defensive and counter-defensive strategies that enable them to infect their hosts. Molecular genetic results showed high genetic variability among Botryosphaeriaceae species, which could be a key determinant to their differing environmental roles on hosts and differences in their virulence. Improved technologies such as whole genome re-sequencing, integrated RNA-Seq, comparative and ab initio approaches for molecular genetics and mutation analysis have revealed possible virulence factors that might be involved in the pathogenicity of these fungi. Several genes involved in the pathogenicity processes of botryosphaeriaceous fungi have been identified and characterized. There are numerous reports on the involvement of phytotoxic metabolites in the pathogenicity of these taxa. Availability of whole genomes, genetic transformation and transcriptome analysis of some botryosphaeriaceous species have contributed towards identifying the biological functions of many genes in a fast and accurate way, enabling these fungi to be used as model organism for molecular research of plant opportunistic fungal pathogens in woody plants. The research on botryosphaeriaceous species will provide understanding of the infection mechanisms, and with designing control strategies against diseases caused by opportunistic fungal pathogens

Redined families of Dothideomycetes: orders and families incertain in Dothideomycetes

peer reviewedNumerous new taxa and classifications of Dothideomycetes have been published following the last monograph of families of Dothideomycetes in 2013. A recent publication by Honsanan et al. in 2020 expanded information of families in Dothideo- mycetidae and Pleosporomycetidae with modern classifications. In this paper, we provide a refined updated document on orders and families incertae sedis of Dothideomycetes. Each family is provided with an updated description, notes, including figures to represent the morphology, a list of accepted genera, and economic and ecological significances. We also provide phylogenetic trees for each order. In this study, 31 orders which consist 50 families are assigned as orders incertae sedis in Dothideomycetes, and 41 families are treated as families incertae sedis due to lack of molecular or morphological evidence. The new order, Catinellales, and four new families, Catinellaceae, Morenoinaceae Neobuelliellaceae and Thyrinulaceae are introduced. Seven genera (Neobuelliella, Pseudomicrothyrium, Flagellostrigula, Swinscowia, Macroconstrictolumina, Pseudobogoriella, and Schummia) are introduced. Seven new species (Acrospermum urticae, Bogoriella complexoluminata, Dothiorella ostryae, Dyfrolomyces distoseptatus, Macroconstrictolumina megalateralis, Patellaria microspora, and Pseu- domicrothyrium thailandicum) are introduced base on morphology and phylogeny, together with two new records/reports and five new collections from different families. Ninety new combinations are also provided in this paper
