Distribution of photoperiod-insensitive alleles Ppd-B1a and Ppd-D1a and their effect on heading time in Japanese wheat cultivars
The genotypes of photoperiod response genes Ppd-B1 and Ppd-D1 in Japanese wheat cultivars were determined by a PCR-based method, and heading times were compared among genotypes. Most of the Japanese wheat cultivars, except those from the Hokkaido region, carried the photoperiod-insensitive allele Ppd-D1a, and heading was accelerated 10.3 days compared with the Ppd-D1b genotype. Early cultivars ...
متن کاملHeritable heading time variation in wheat lines with the same number of Ppd-B1 gene copies
The ability of plants to identify an optimal flowering time is critical for ensuring the production of viable seeds. The main environmental factors that influence the flowering time include the ambient temperature and day length. In wheat, the ability to assess the day length is controlled by photoperiod (Ppd) genes. Due to its allohexaploid nature, bread wheat carries the following three Ppd-1...
متن کاملAllelic Variation in Developmental Genes and Effects on Winter Wheat Heading Date in the U.S. Great Plains
Heading date in wheat (Triticum aestivum L.) and other small grain cereals is affected by the vernalization and photoperiod pathways. The reduced-height loci also have an effect on growth and development. Heading date, which occurs just prior to anthesis, was evaluated in a population of 299 hard winter wheat entries representative of the U.S. Great Plains region, grown in nine environments dur...
متن کاملPurified Protein Derivative--PPD.
A 55-year-old physician had a PPD made as part of a clinical evaluation. Laboratory tests were unremarkable and PPD, read in 48 hours, showed an area of induration of 18 mm and an erythema of 51 mm (Panel A). A 2 mm punch biopsy was done in the center of the induration 96 hours after the injection. Histopathology showed an intense perivascular cuffing with macrophages and lymphocytes and edema ...
