Molecular Characterization of Factors Affecting Flowering Time in Hexaploid Oat
نویسندگان
چکیده
Flowering time is a decisive factor in the adaptation of oat to sub-tropical environments. Varieties grown in southern Brazil show varying response to low temperature-dependant floral initiation, a process called vernalization. Vernalization is defined as “the acquisition or acceleration of the ability to flower by a chilling treatment” (Chouard 1960). Genetic analyses have identified at least three genes that affect vernalization requirement in wheat and barley: VRN1, VRN2, and FT (VRN3). These genes are implicated in both the vernalization response as well as the response to day length.

Flowering time is an important horticultural trait in almond since it is essential to avoid the late frosts that affect production in early flowering cultivars. Evaluation of this complex trait is a long process because of the prolonged juvenile period of trees and the influence of environmental conditions affecting gene expression year by year. In this research flowering time was studied in an...
متن کاملSystematic Investigation of FLOWERING LOCUS T-Like Poaceae Gene Families Identifies the Short-Day Expressed Flowering Pathway Gene, TaFT3 in Wheat (Triticum aestivum L.)
To date, a small number of major flowering time loci have been identified in the related Triticeae crops, bread wheat (Triticum aestivum), durum wheat (T. durum), and barley (Hordeum vulgare). Natural genetic variants at these loci result in major phenotypic changes which have adapted crops to the novel environments encountered during the spread of agriculture. The polyploid nature of bread and...
متن کاملDiscrimination of the closely related A and D genomes of the hexaploid oat Avena sativa L.
A satellite DNA sequence, As120a, specific to the A-genome chromosomes in the hexaploid oat, Avena sativa L., was isolated by subcloning a fragment with internal tandem repeats from a plasmid, pAs120, that had been obtained from an Avena strigosa (As genome) genomic library. Southern and in situ hybridization showed that sequences with homology to sequences within pAs120 were dispersed througho...
متن کاملThe first doubled haploid linkage map for cultivated oat.
To date, all linkage maps of hexaploid oat (Avena sativa L.) have been constructed using recombinant inbred lines (RILs). Doubled haploids (DHs), however, have the advantage over RILs of their comprehensive homozygosity. DHs have been used for mapping in several cereal species, but in oats the production of large DH populations has only recently become an option. A linkage map of hexaploid oat ...

A cultivated oat linkage map was developed using a recombinant inbred population of 136 F6:7 lines from the cross 'Ogle' x 'TAM O-301'. A total of 441 marker loci, including 355 restriction fragment length polymorphism (RFLP) markers, 40 amplified fragment length polymorphisms (AFLPs), 22 random amplified polymorphic DNAs (RAPDs), 7 sequence-tagged sites (STSs), 1 simple sequence repeat (SSR), ...
