This study was conducted to characterize Dioscorea spp. in Kenya using morphological and molecular characteristics. Data on 22 morphological traits were subjected to cluster analysis and multivariate analysis using principal component (PCA). The dend

Macro-morphological features traditionally used to segregate genera in Parmeliaceae have been shown to be highly plastic, placing limits on their taxonomic value. Here we aim to elucidate the evolutionary relationships of the genera Relicina and Reli

Lichens that reproduce by means of vegetative propagules (soredia or isidia) are generally thought to have broad geographic distributions. However, recent studies have shown that some asexually reproducing lichens with broad distribution may be compr

Crude leaf extracts from medicinal plants were screened for in vitro antifungal properties against clinical isolate of Candida albicans. The antifungal test was carried out using the Kirby Bauer method. All the extracts from the plants tested showed

A number of lichen-forming fungal species are widely distributed. Here, we investigate biogeographic patterns in a widely distributed isidiate taxon – Parmelinella wallichiana – using molecular sequence data. Our results revealed that Parmelinell

The main aim of the study was to determine the antimicrobial potency of the plant extracts from leaves of Aloe secundiflora, Bulbine frutescens, Tagetes minuta and Vernonia lasiopus when used in combinations. The extracts were used against Gram negat

Many phenotypical features traditionally used to classify genera in Parmeliaceae and in lichens in general have evolved several times independently, potentially limiting their taxonomic utility. Here, we aim to elucidate evolutionary relationships of

Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and unaffordable to most peasant farmers

The phylogenetic position of the monotypic genus Bulborrhizina is studied using molecular data from three loci (mtSSU, nuLSU and ITS) aligned with sequences from 95 other samples of parmelioid lichens. Bulborrhizina africana clusters within the predo
