Molecular and cytological analysis of a mariner transposon from Hessian fly
Article Abstract:
Mariner class of transposable elements, designated as Desmar1, are present in the genome of Hessian fly, Mayetiola destructor. Desmar1 has perfect inverted repeats and an open reading frame coding for transposase. The transposon is 1288 bp long and the inverted terminal repeats are of 28 bp. The open reading frame starts at nucleotide position 168, is 1041 bp long and terminates with GAA and TAA. Desmar1 shows similarity to Mos1 mariner element both at DNA and amino acid level. In situ hybridization with polytene chromosomes shows that it is predominantly present near the paracentromeric region.

Genetics of virulence in the Hessian fly to resistance gene H13 in wheat
Article Abstract:
The phenotypic expression of virulence in the insect pest of wheat, Hessian fly, with respect to the wheat resistance gene H13, was studied using progenies produced from cross-matings among lines of Hessian fly bearing distinct genotypes. The results confirmed that virulence is controlled by a single recessive, sex-linked gene. It was further demonstrated that virulence/avirulence in the Hessian fly operates on a gene-for-gene basis with wheat's H13 resistance gene.

An STS linked to a Hessian fly locus controlling virulence to resistance gene H13 in wheat
Article Abstract:
A study was conducted to analyze a sequence tagged site associated with the locus controlling virulence in Hessian fly to resistance gene H13 in wheat and the white-eye locus. The loci were mapped through an examination of recombinant genotypes in backcross progenies. Crosses were carried out to generate backcross progenies that were reciprocal crosses between the white-eyed, HI3 avirulent and dark-eyed H13 virulent lines.
