Polyploid formation in cotton is not accompanied by rapid genomic changes.
Signs of genomic additivity and epigenetic stasis during allopolyploid formation provide a contrast to recent evidence from several model plant allopolyPloids, most notably wheat and Brassica, where rapid and unexplained genomic changes have been reported.
Optimization of a reliable, fast, cheap and sensitive silver staining method to detect SSR markers in polyacrylamide gels.
Developpement d’une methode fiable, rapide, economique et sensible de coloration au nitrate d’argent pour la detection des marqueurs SSR sur gels de polyacrylamide. Une methode fiable, rapide,…
Survey of pigeonpea production systems, utilization and marketing in semi-arid lands of Kenya
In order to assess the status of pigeonpea (Cajanus cajan (L.) Millsp.) production in Kenya, two surveys were carried out in Makueni and Mbeere Districts in areas representative of the main…
Improved RAPD amplification of recalcitrant plant DNA by the use of activated charcoal during DNA extraction
The results suggest that the use of activated charcoal in DNA extraction enhances RAPD amplification, and this technique was initially developed for cotton but has been applied successfully to other recalcitrant plants such as coffee, rubber tree, cassava and banana.
Genetic diversity of the African geocarpic legume Kersting’s groundnut, Macrotyloma geocarpum (Tribe Phaseoleae: Fabaceae)
Characterization of Kenyan Isolates of Fusarium udum from Pigeonpea [Cajanus cajan (L.) Millsp.] by Cultural Characteristics, Aggressiveness and AFLP Analysis
This is the first report on the study of genetic variability of F. udum using DNA analysis and AFLP had no relationship with cultural characteristics, aggressiveness and geographical origin of the isolates.
Introduction of Australian diploid cotton genetic variation into upland cotton
The results confirm that cotton male gametes are more limited than female gameters in the number of supernumerary chromosomes they can carry.
Insecticidal effect of Jatropha curcas oil on the aphid Aphis fabae (Hemiptera: Aphididae) and on the main insect pests associated with cowpeas (Vigna unguiculata) in Niger
The biocidal effect of the treatments applied, which increases with the concentration, is demonstrated on the black bean aphid and on cowpea crops, where J. curcas oil concentrations make it possible to greatly increase yields compared to the untreated control.
Polyploid formation in cotton is not accompanied by rapid genomic changes
Signs of genomic additivity and epigenetic stasis during allopolyploid formation provide a contrast to recent evidence from several model plant allopoly ploids, most notably wheat and Brassica, where rapid and unex- plained genomic changes have been reported.
Study of the early abortion in reciprocal crosses between Phaseolus vulgaris L. and Phaseolus polyanthus Greenm.
Results suggest that the appropriate time for embryo rescue when Phaseolus polyanthus is a female partner is at the early globular stage, and the main causes of abortion are endothelium proliferation and hypertrophy of the vascular elements.
