Diversity of Late Blight Resistance Genes in the VIR Potato Collection.

Late blight (LB) caused by the oomycete (Mont.) de Bary is the greatest threat to potato production worldwide. Current potato breeding for LB resistance heavily depends on the introduction of new genes for resistance to ( genes).

Genome-specific SCAR markers help solve taxonomy issues: a case study with Sinapis arvensis (Brassiceae, Brassicaceae).

Premise Of The Study: Traditional taxonomy and nomenclature of Brassiceae (Brassicaceae) species do not reflect their phylogeny. Revision of the species and generic limits supported by extensive molecular data seems crucial.

Methods And Results: Genome-specific polymorphisms extracted from non-coding and coding sequences were used to develop 14 sequence characterized amplified region (SCAR) markers specific for the Brassica B genome.

The structure of two CONSTANS-LIKE1 genes in potato and its wild relatives.

Day length controls development in many plants. In Arabidopsis thaliana, the CONSTANS (CO) gene has been firmly established as a key component in the photoperiodic pathway of floral transition; less is known about CONSTANS-LIKE1 (COL1) orthologues of this gene in Arabidopsis and several other species. The CONSTANS protein comprises two B-box-type zinc fingers, CCT domain, and a variable middle region (MR) which corresponds to exon 2 in the COL1 genes of Solanum species.
