The genome locations of the wound-response genes that were expressedduring the post-harvest physiological deterioration (PPD) of cassava, suchas phenylalanine ammonia lyase, ?-1.3 glucanase, hydroxyprolinerich glycoprotein, catalase, 1-aminocyclopropane 1-carboxylate, cysteineprotease inhibitor, ...

Three RFLP maps, as well as several RAPD maps have been developed in common bean (Phaseolus vulgaris L.). In order to align these maps, a core linkage map was established in the recombinant inbred population BAT93×Jalo EEP558 (BJ). This map has a total length of 1226?cM and comprises 563 markers,...

Development of a core linkage map and alignment of RFLP maps

Storage roots of cassava (Manihot esculenta Crantz) exhibit a rapid post-harvest physiological deterioration (PPD) response that can occur within 24 72 h of harvest. PPD is an enzymatically mediated oxidative process with parallels to plant wound, senescence and defence responses. To characterise...

The recombination and copy number shifting activities of the plant mitochondrial genome are widely documented across plant genera, but these genome processes have not been as well examined with regard to their roles in plant evolution. Because of the extensive plant collections of Phaseolus spp a...

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...


Chavarriaga Aguirre, PaulMaya, M.M.Tohme, Joseph M.Duque E., Myriam CristinaIglesias, C.A.Bonierbale, Merideth W.Kresovich, SKochert, G[Using microsatellites, isozymes and AFLPs to evaluate genetic diversity and redundancy in the cassava core collection and to assess the usefulness of DNA-BASED markers to maintain germplasm collections]Using microsatellites, isozymes and AFLPs to evaluate genetic diversity and redundancy in the cassava core collection and to assess the usefulness of DNA-BASED markers to maintain germplasm collections

Restriction fragment analysis was used to determine the variation of chloroplast DNA (cpDNA) among and within different species of Passiflora. Total DNAs of 35 accessions, representing 12 species, were digested with four restriction endonucleases. Southern blots of the restriction digests were th...

EI síndrome de la hoja amarilla es una enfermedad de la calla de azúcar que fue detectada en Colombia por primera vez en 1998. Cenicaña está tratando de lograr un control eficiente de la enfermedad utilizando diferentes herramientas pertenecientes a diversas áreas como entomología, patología, bio...

The lack of good quality planting material of farmers' cassava varieties, produced locally and at low cost, is a major constraint limiting the expansion of cassava production in Colombia. This article describes the adaptation of conventional cassava propagation to a low-input scheme for rural tis...
