HTS-1 is a new kind of pistillody wheat. All or parts of its stamen are transformed into pistils or pistil-like structures, and it has more seed sets per floret than normal wheat under normal cultivation conditions. To investigate the expression divergence in this mutant, an annealing control primer system was used to identify differentially expressed genes (DEGs) in the young spikelets. As a result, three DEGs, including HDB2, HGF2, and HCG4, were detected, with variable expression in HTS-1 and the control. After further confirmation using real-time reverse transcription polymerase chain reaction analysis, these genes were overexpressed in HTS-1 wheat. NGF2 was identified in the double ridge to floret differentiation stages; HDB2 and HCG4 were identified in the stage of pistil and stamen-differentiating. Therefore, we inferred that the homeotic transformation of stamens into pistil-like structures occurred during the early stage of stamen development. Sequence alignment analysis revealed that HDB2 encodes a putative protein of 189 amino acids, with high homology to the DEAD-box ATP-dependent RNA helicase, and HCG4 was identical to the Chinese spring wheat cDNA clone predicted protein according to GenBank. However, NGF2 was not found to have significant similarity to any reported proteins, suggesting it is a new functional gene in wheat. The results suggest that HDB2, HCG4, and HGF2 are minor genes contributing to pistillody trait formation in HTS-1.

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gene--the BCO2 gene has relationship with milk color and meat fat color, which is dependent on content of β-carotene. We analyzed these two genes and their relationship with milk performance traits (daily milk, fat and protein yield, somatic cell count, SCC) in one cattle population, Czech Fleckvieh (N = 152). All animals were milked twice a day and kept in the same environmental conditions. The Fleckvieh is a typical Czech cattle breed farming for milk and meat production. It is the most common breed in the Czech Republic. DNA was isolated from milk or from hairs. Genes were analyzed using PCR-RFLP, frequencies of alleles and genotypes were calculated and association analysis was performed using a GLM Procedure in SAS. Statistical analysis established that the CSN3 gene has no statistically significant influence on daily milk, fat and protein yield and SCC. Compared to other references this result can be explained by, e.g., small group of animals and different cattle breed. The BCO2 gene (genotypes AA and AG) shows a statistically significant relationship (P = 0.05) with daily milk, protein yield and SCC.
