Human chromosome (Chr) 18(HSA 18) contains approximately 85 million base pains of DNA. Thirty genes and pseudogenes have been mapped to HSA 18 by somatic cell genetics or in situ hybridization. Two bovine genes - Yamaguchi sacroma viral oncogene homology 1 (YESI) and desmocollin type 1 (DSC1) - h...

The triploid genome of plantain (Musa spp., AA group) has been considered intractable to genetic improvement because of the production of putatively homogeneous 2n (= 3.r) gametes. Plantain breeding schemes have been based on the hybridization of 2n megaspores from the triploid plantain and haplo...

A preliminary search for QTLs in a cattle F2 resource populations segregating for trypanotolerance has revealed three large candidate chromosomal regions (Bta02, Bta05, Bta07). In order to narrow down the position of the trypanotolerant QTLs, we are building comparative chromosomal maps between c...

Spontaneous sexual and asexual polyploids occur in cassava. The cassava polyploid breeding strategies using these polyploidization processes are discussed. Sexual polyploidization has advantages over asexual polyploidization in terms of viability of gametes, heterosis, vigor, plant architecture, ...

Plantain and banana (Musa spp) breeding involves crossing 3x (triploid) landraces to 2x (diploid) accessions as female and male parents, respectively, selecting 4x (tetraploid) and 2x primary hybrids from the 3x - 2x progenies, and crossing 4x - 2x hybrids to produce secondary 3x hybrids. In thes...

Oligo painting FISH was established to identify all chromosomes in banana (Musa spp.) and to anchor pseudomolecules of reference genome sequence of Musa acuminata spp. malaccensis “DH Pahang” to individual chromosomes in situ. A total of 19 chromosome/chromosome-arm specific oligo painting probes...

An alternative approach for the direct analysis of chromosome regions corresponding to economical traits, based on chromosome microdissection, is described. Large fragment clones isolated with primer pairs designed from chromosome fragment-specific DNA sequences were localized by fluorescence in ...

A Trypanosoma brucei brucei DNA repeat sequence termed NlaIII repeat (NR) was originally isolated from a multidrug-resistant field isolate CP547 [Jamnadass, R., 1995. Identification and characterisation of an extrachromosomal element from a multidrug-resistant isolate of T. brucei brucei, Ph.D. t...
