Total seed protein variability in a sample of 163 entries of year-bean (Phaseolus polyanthus), including wild, feral and cultivated forms of the whole range of distribution in Latin America was studied using 1-dimensional SDS/PAGE and 2-dimensional IEF-SDS/PAGE. Ten different patterns were observ...

The taxonomic classification of the wild Lima bean complex needs to be assessed to select species for use in breeding programs and to identify genetic resources for conservation. The objectives of this study were to determine the genetic relationships among, and the phylogeny of, wild Lima bean (...

African oil palm ringspot virus (AOPRV) had been previously described as a fovea-like virus associated with a lethal disease of African oil palm (Elaeis guineensis) in South America. The original report was based on partial sequence and a distant relationship between AOPRV and Apple stem pitting ...

Morphological variation was studied in 124 accessions from 61 Passiflora L. species. Twenty-four quantitative descriptors selected for their high variation among subgenera were submitted to a principal component analysis. The first principal component (32% of total variance) was associated with f...

Question: To what extent can aerial photography be used for taxonomic identification of Amazonian tree crowns? Objective: To investigate whether a combination of dichotomous keys and a web-based interface is a suitable approach to identify tree crowns. Location: The fieldwork was conducted at T...
