Transgenic durum wheat by microprojectile bombardment of isolated scutella

Article Abstract:

A regeneration protocol was developed using isolated scutella to standardize a durum wheat transformation procedure for the selection of herbicide resistance in this species. The durum wheat variety used in the experiments are agronomically important strains. The development of a transformation protocol for these plants has important implications in the introduction of agronomically important traits in commercial crops.

Inter- and intragenomic chromosome pairing in haploids of durum wheat

Article Abstract:

Durum euhaploids were synthesized with and without the chromosome pairing suppresser gene Ph1 to examine chromosome pairing and chiasma frequency. Fluorescent genomic in situ hybridization (GISH) on meiotic chromosomes was used to study specificity of chromosome pairing. Chromosomes of the A and B genomes in the ph1c-haploids showed increasing pairing, and the potential of intergenomic pairing was realized more fully in the substitution haploids. Durum haploids are useful tools for studying genomic relationships in durum wheat.
