Nutritional quality of phaseolin types and morphotypes of green bean (Phaseolus vulgaris L.) Agrociencia
Carović-Stanko,Klaudija; Maloić,Mario; Pintar,Jasna; Liber,Zlatko; Radosavljević,Ivan; Bedeković,Dalibor; Guberac,Sunčica; Očić,Vesna; Lazarević,Boris.
Abstract The long tradition of green bean (Phaseolus vulgaris L.) cultivation in Croatia has resulted in the development of a landraces adapted to specific areas and chosen to suit different dietary habits. The hypothesis of our study was that nutritional quality (content of proteins, sugars, fibres, calcium, potassium and phosphorus in fresh pods) of 14 widely grown Croatian green bean accessions is affected by origin and morphotype. The analysed accessions were grown in non-replicated field plots where morphotypes were classified. The gene pool of adscription (Andean vs. Mesoamerican) of each accession was determined with the phaseolin marker, whereas nutritional quality traits were analysed according to standard analytical methods. The relationships...

Genetic diversity in Mexican wild populations of the Great Curassow (Crax rubra) Biota Neotropica
Morales-Contreras,Jonathan; Escalante,Patricia; Matías-Ferrer,Noemí.
Abstract The Great Curassow (Crax rubra) is a Neotropical bird with a wide distribution; it is classified under different threat categories and is listed as a vulnerable species by the IUCN. The Official Mexican Standard, the NOM-059-SEMARNAT-2010, indicates that the Great Curassow is a threatened species, and the subspecies Crax rubra griscomi, which is restricted to the island of Cozumel, is classified as critically endangered. Habitat loss and fragmentation, hunting, overexploitation, and illegal trade are among the main factors that have placed the bird at an endangered status. The objective of the present study was to determine the genetic structure and variation of the species within the Mexican populations of Crax rubra by using three mitochondrial...

Allelic relationships of anthracnose (Colletotrichum lindemuthianum) resistance in the common bean (Phaseolus vulgaris L.) cultivar Michelite and the proposal of a new anthracnose resistance gene, Co-11 Genet. Mol. Biol.
Gonçalves-Vidigal,Maria Celeste; Silva,Claudete Rosa da; Vidigal Filho,Pedro Soares; Gonela,Adriana; Kvitschal,Marcus Vinícius.
The genetic resistance of Phaseolus vulgaris L. cultivar Michelite to races 8 and 64 of Colletotrichum lindemuthianum, causal agent of bean anthracnose, was characterized. Crosses were made between Michelite and Mexico 222 cultivars and the F2 population was inoculated with race 64 in order to study the inheritance of resistance to anthracnose in Michelite. The segregation of F2 population fitted in a ratio of 3R:1S, showing the presence of a dominant gene in Michelite gene conditioning resistance to race 64. Allelism tests were conducted with F2 populations derived from crosses between Michelite and AB 136, AND 277, BAT 93, Cornell 49-242, G 2333, Kaboon, Mexico 222, Michigan Dark Red Kidney (MRDK), Ouro Negro, Perry Marrow, PI 207262, TO, TU, and Widusa....

Genetic variability in common wheat germplasm based on coefficients of parentage Genet. Mol. Biol.
Bered,Fernanda; Barbosa-Neto,José F.; Carvalho,Fernando I.F. de.
The characterization of genetic variability and an estimate of the genetic relationship among varieties are essential to any breeding program, because artificial crosses among less similar parents allow a larger segregation and the combination of different favorable alleles. Genetic variability can be evaluated in different ways, including the Coefficient of Parentage (COP), which estimates the probability of two alleles in two different individuals being identical by descent. In this study, we evaluated the degree of genetic relationship among 53 wheat genotypes, and identified the ancestor genotypes which contributed the most to the current wheat germplasm, as a prediction of the width of the genetic base of this cereal. The results revealed a mean COP...

Phytogeographical origin of Madeiran common beans based on phaseolin patterns PAB
Silva,Emanuel Marques da; Correia,Anísia Soraia Abreu; Lopes,Nuno Alexandre Amaral; Nóbrega,Humberto Gil Moreira; Ganança,José Filipe Teixeira; Domingues,Ana Maria; Khadem,Manhaz; Slaski,Jan Jacek; Carvalho,Miguel Ângelo Almeida Pinheiro de.
The objective of this work was to determine the geographic origin of the Madeiran common bean (Phaseolus vulgaris) gene pool. Phaseolin patterns of 50 accessions representing the diversity of common bean collected in Madeira, Portugal, and conserved in the ISOPlexis Germplasm Bank, were analysed using the Experion automated electrophoresis system, based on lab-on-a-chip technology. Five common bean standard varieties with typical phaseolin patterns were used to determine the phytogeographical origin of the Madeiran common bean accessions. Ninety two percent of the accessions exhibited a phaseolin pattern consistent with the one of common bean types belonging to the Andean gene pool, while the origin of the remaining 8% of the accessions was...
