Reproductive stage frost poses a major constraint for wheat production in countries such as Australia. However, little progress has been made identifying key genes to overcome the constraint. In present study, severe event hit two large-scale field trials consisting of six doubled haploid (DH) populations at reproductive (young microspore stage) Western Australia, leading identification 30 robu...

Ancient and modern 183 varieties of winter 23 spring types development bread wheat (Triticum aestivum L.) selected Ukrainian state institutions private companies are characterized by alleles Ppd-D1, Ppd-B1, Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. ...

Combined radioligand binding and light microscope autoradiography techniques were used for investigating the pharmacological profile and the microanatomical localisation of dopamine receptor subtypes in the cardiovascular system and in the kidney. In superior mesenteric and renal arteries the predominant dopamine D1-like receptor belongs to the D5 (or D1b) subtype. This site is located within s...

In soybean, asynaptic and desynaptic mutants lead to abnormal meiosis and fertility reduction. Several male-sterile, female-sterile mutants have been identified and studied in soybean, however, some of these mutants have not been mapped to locations on soybean chromosomes. The objectives of this study were to molecularly map five male-sterile, female-sterile genes (st2, st4, st5, st6, and st7) ...

nloaded DNA damage response (DDR) activates downstream pathways including cell cycle checkpoints. The D1 gene is overexpressed or amplified in many human cancers and is required for gastrointestinal, , and skin tumors in murine models. A common polymorphism in the human cyclin D1 gene is atively spliced, resulting in cyclin D1a and D1b proteins that differ in their carboxyl terminus. Cyclin ere...

In recent years, the distribution of dopamine receptor subtypes among the principal neurons of the neostriatum has been the subject of debate. Conventional anatomical and physiological approaches have yielded starkly different estimates of the extent to which D1 and D2 class dopamine receptors are colocalized. One plausible explanation for the discrepancy is that some dopamine receptors are pre...

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 ...

The spontaneous fasciation mutation generates novel developmental diversity in cultivated soybean, Glycine max (L.) Merrill. An increased apical dominance in the mutant inhibits axillary buds, causes a branchless phenotype, and restricts reproduction to shoot apices. The fasciation mutation is encoded by a recessive (f) allele at a single locus. The mutation, despite its importance in soybean d...

Establishment of seedlings is a key factor in achievement of uniform field stands and, consequently, stable yields. Under Mediterranean conditions, soil moisture in the upper layer is limited and seedlings may be exposed to frequent dehydration events. The presence of the Reduced height (Rht)-B1b and Rht-D1b semi-dominant dwarfing alleles results in insensitivity to gibberellin (GAI) and, hence...
