It is shown that in addition to direct effects on plant height GA-sensitive and GA-insensitive dwarfing genes have pleiotropic effects on all studied traits except the number of fertile spikelets. Presence of the dwarfing genes in the genotype of tall forms led to the decrease of stem and ear length, and at the same time to the increase of ear density. The number of spikelets per spike decreased due to sterile spikelets, whereas the number of fertile spikelets did not change. There was a significant increase in the number of grains per ear as a result of increasing of spikelets in ears. The number and weight of grains did not decrease, even though the plants were characterized by a smaller number of productive stems. The presence of Rht8x allele on genetic background of variety Stepnyak resulted in a significant decrease of plants productivity. However, in combination with Ppd-D1a allele plants with Rht8x increased the potential productivity, and surpassed the parental form (Rht8a Ppd-D1b). The presence of Rht-B1e allele resulted in reduction of grain mass per spike and 1000-grain weight, increase of l/h, and left the number of grains per spike stable in comparison with Rht8c.</p>","PeriodicalId":23230,"journal":{"name":"TSitologiia i genetika","volume":"50 1","pages":"26-35"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34453232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chargaff was born in Chernivtsi (Austria-Hungary, now Ukraine) but during the First World War his family was forced to move to Vienna. After graduating from the University of Vienna, Chargaff worked in Berlin, where he studied bacterial lipids. Due to Nazis coming to power in Germany, Chargaff moved to Paris and later (1935) emigrated to the USA and obtained a position at Columbia University, where he initially investigated the role of phospholipids in blood clotting. In 1944, applying novel methods Chargaff initiated intensive investigation of the chemical composition of nucleic acids from taxonomically distant species and established two rules which were later named after him. The first Chargaff's rule provided a significant support to Watson and Crick in construction of their double helical DNA model. The explosion of atomic bombs over Hiroshima and Nagasaki forced Chargaff to think about the moral responsibility of researchers and science to mankind. He begins to raise these issues in the press and manifests himself as a talented journalist, who criticized the bureaucratization of science and its transformation into a way of earning money. Despite decades of life in America, spiritually Erwin Chargaff always remained a European, who never forgot his roots and always remembered his native land.</p>","PeriodicalId":23230,"journal":{"name":"TSitologiia i genetika","volume":"50 1","pages":"80-7"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34615158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study a standardized reagent protocol for total RNA extraction was designed for bovine oocytes and embryos, which is considered specific and less expensive. For such purpose oocytes (n = 795) recovered from about 80 ovaries were divided in three groups: Group 1 modified Trizol (MTP, n = 355); Group 2 Guanidinium thiocyanate protocol (GNTC, n = 140) and Group 3 Commercial Kit protocol (CKP, n = 60). Oocytes belonging to group 1 (n = 100) and 3 (n = 20) were subjected to vitrification using two cryoprotectants 1,2 propandiol (PROH) or Dimethylsulfoxide (DMSO). The 240 remaining oocytes were divided into 3 groups in which 100 were used, in fresh, for in vitro fertilization, and 140 oocytes were vitrified using PROH (n = 70) and DMSO (n = 70) as cryoprotectants, being then fertilized in vitro after thawing. Embryos were used nine days after fertilization. Gene amplification (SDHA, (GAPDH and DNMT1) was performed in oocytes, and gene quantification (DNMT1) in in vitro produced embryos at the stage of blastocyst (n = 10). Efficiency of the extraction was further compared. The purity of all samples to different protocols ranged from 1.10 to 1.25 for GNTC protocol; from 2.05 to 2.63 for the CKP and from 1.50 to 2.11 for the developed MTP, being the last one nearest to the expected purity levels for RNA samples (1.7 to 2.0). On average, for 30 fresh oocytes, from spectrophotometer readings, total RNA concentration was 127.8 ± 9.3 ng μl(-1) for MTP, against 46.4 ± 9.5 ng μl(-1) from CKP and 476 ± 12.9 ng μl(-1) for GNTC protocol. Using the MTP to evaluate RNA in 30 vitrified/thawed oocytes, resulted in a total RNA concentration of 61.3 ± 3.3 ng μl(-1) and 40.0 μ 12.4 ng μ(-1), respectively for DMSO and PROH. Regarding total RNA concentration and purity, in blastocyst stage, more purity was observed in DMSO as compared to PROH (1.8 vs 1.2) (p < 0.05). Better results were also observed on the MTP for gene amplification when compared with the other protocols.
