Two previously unknown Phytophthora species associated with brown rot of Pomelo (Citrus grandis) fruits in Vietnam

27.03.2017, Tomáš Májek

Two distinct Phytophthora taxa were found to be associated with brown rot of pomelo (Citrus grandis), a new disease of this ancestral Citrus species, in the Vinh Long province, Mekong…

Effect of Artificial Light Conditions on Local and Systemic Resistance Response of Tobacco to TMV Infection

16.05.2017, Tomáš Májek

Our and literature studies indicated that systemic acquired resistance (SAR) is effectively inducible in greenhouse, and certain artificial light sources cause non-optimal growth of tobacco plants. Therefore, the morphological characteristics,…

27.06.2017, Tomáš Májek

Based on molecular evidence and morphological analyses, a new species in the genus Trametopsis is revealed. Trametopsis aborigena sp. nov. is proposed and described from South America. Molecular phylogenetic analyses of ITS and LSU rDNA…

In vitro growth response of Phytophthora cactorum, P. nicotianae and P. × pelgrandis to antibiotics and fungicides

04.07.2017, Tomáš Májek

The reactions of isolates of Phytophthora cactorum, P. nicotianae and P. × pelgrandis to metalaxyl, mancozeb, dimethomorph, streptomycin and chloramphenicol were tested to obtain information about the variability of resistance…

19.01.2018, Tomáš Májek

Porodaedalea chinensis is described and illustrated as a new species occurring on Pinus yunnanensis from southwestern China based on morphological and molecular characters. Phylogenetic analyses of the combined internal transcribed…

Canker and decline diseases caused by soil- and airborne Phytophthora species in forests and woodlands

02.05.2018, Tomáš Májek

Most members of the oomycete genus Phytophthora are primary plant pathogens. Both soil- and airborne Phytophthora species are able to survive adverse environmental conditions with enduring resting structures, mainly sexual oospores, vegetative chlamydospores and…
