Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum accessions representing the species C. annuum...

The Fungi comprise a diverse kingdom of eukaryotes that are characterized by a typically filamentous but sometimes unicellular vegetative form, and heterotrophic, absorptive nutrition. Their simple morphologies and variable ecological strategies have confounded efforts to elucidate their limits, phylogenetic relationships, and diversity. Here we review progress in developing a phylogenetic clas...

The phylogenetic relationships among the Peninsular Malaysian orchid genus Coelogyne were studied by morphological characteristics and sequence data of internal transcribed region (ITS) from nuclear ribosomal DNA (nrDNA). is a large about 200 species distributed in pantropical areas Himalayas, Sri Lanka, India, Southern China throughout South East Asia to Papua New Guinea. widely accepted previ...

A new taxon of conifers (Coricladus quiteriensis) is described based on megafloristic remains from the roofshale level at the Quiteria Outcrop (Rio Bonito Formation-Lower Permian-Southern Parana Basin-Rio Grande do Sul-Brazil). This megafloristic community is included in the Botrychiopsis Zone--Botrychiopsis valida Sub-Zone (Kungurian/Roadian). The assemblage, preserved as impressions, do not p...

Partial or complete sterility is of frequent occurrence in species crosses. Within the same genus certain species are sterile when crossed while ather combinations are completely fertile. Partial sterility may cause the elimination of certain classes of gametes and prevent desired recombinations of characters in the second generation. Sterility may also cause an abnormal vegetative development....

Abstract Bambara groundnut is a reliable source of carbohydrates and protein in rainforest agroecology, but limited research had been done few varieties commercialised. The magnitude phenotypic variability, character association, contribution characters to seed yield were investigated among 50 accessions received from IITA, Nigeria. Field evaluation took place during the 2017 – 18 cropping seas...

ORCHARD, A.E. & DAVIES, J.B., 1985 (3I:vii): Oreoporanthera, a New Zealand "endemic" plant genus discovered in Tasmania. Pap. Proc. R.Soc. Tasm. 119:61-63. ISSN 0080-4703. Tasmanian Herbarium, GPO Box 252C, Hobart, Tasmania, and Department of Agriculture, Marine Board Building, Hobart, Tasmania. Recent collections near Mt Anne in southwestern Tasmania have extended the known range of the previo...

Aspergillus flavus is the major producer of carcinogenic aflatoxins in crops worldwide and is also an important opportunistic human pathogen in aspergillosis. The sexual state of this heterothallic fungus is described from crosses between strains of the opposite mating type. Sexual reproduction occurred between sexually compatible strains belonging to different vegetative compatibility groups. ...

A polyphasic study of strains originally received as Bacillus (now Virgibacillus) pantothenticus, along with strains representing species belonging to Bacillus, Halobacillus and Paenibacillus, was undertaken using amplified rDNA restriction analysis (ARDRA), fatty acid methyl ester (FAME) analysis, SDS-PAGE of whole-cell proteins and routine diagnostic characters comprising 61 biochemical tests...

Epichloë species (Clavicipitaceae, Ascomycota) are the causal agents of choke disease of grasses. This disease is characterized by the presence of cylindrical fungal stromata which wrap the immature inflorescences and inhibit the normal development of reproductive tillers. Using phenotypic and molecular characters, as well as mating compatibility tests, the fungus causing choke disease in Brach...
