ABSTRACT: In this study, a non-destructive, high-throughput, endosperm-based DNA extraction method was developed. To verify the non-destructive nature of this method, a germination test was performed on 288 seeds after sampling their endosperm, which gave a seedling emergence rate that was higher (97.6%) than that of the control group (92%). To confirm the feasibility of the new method, DNA was extracted from plants of a BC1F2 population by two different methods, namely, from endosperm using our rapid, high-throughput method (ER-DNA) and from young leaves emerging from the same sampled seed using the CTAB method (LC-DNA). The ER-DNA was undetectable by agarose gel electrophoresis, but was found to be an adequate replacement for LC-DNA for the amplification and detection of simple sequence repeats (SSRs). Further analysis revealed that ER-DNA was generally suitable for the generation of specific 500-750-bp fragments, but not for the amplification of 1,000-2,000-bp fragments. Our rapid, high-throughput method therefore has no deleterious effects on wheat seeds and yields DNA for SSR genotyping that is a suitable alternative to traditionally obtained DNA.

Дана информация об изучении коллекции гибридов F1томата (Solanum lycopersicum L.) зарубежной селекции различных фирм-оригинаторов, рекомендованных производителями семян как толерантные к вирусу желтой курчавости листьев томата. Все гибриды обладали комплексом хозяйственно ценных признаков и набором генов устойчивости к основным заболеваниям томата, в том числе к новому для юга России опасному патогену с максимальным потенциальным риском – вирусу желтой курчавости листьев томата (Tomato yellow leaf curl virus — TYLCV). Исследования проведены в 2017-2018 годах в лаборатории пасленовых культур ООО «НИИСОК» и в лаборатории молекулярной диагностики растений ООО «Семеновод». Всего было протестировано 34 гибрида F1 томата. Гибриды оценивали по совокупности хозяйственно ценных признаков, также проводили молекулярно-генетический анализ на наличие и аллельное состояние основных генов устойчивости: к вирусу табачной мозаики (Tm2а), фузариозному увяданию (I2), вертициллезному увяданию (Ve), к кладоспориозу (Cf9), нематодам (Mi1.2), вирусу бронзовости томата (Sw5), вирусу желтой курчавости листьев томата (Ty3a). Установлено, что все проанализированные гибриды томата с заявленной оригинаторами семян устойчивостью к вирусу желтой курчавости листьев были гетерозиготны по гену Ty3a. На основании проведенных исследований и с учетом требований рынка разработаны модели гибридов F1 томата юга России. Перспективный гибрид томата должен обладать индетерминантным типом роста с укороченными междоузлиями (4,5-5 см) а также хорошей облиственностью. Плоды томата должны быть с красной равномерной окраской без зеленого пятна у плодоножки, с плоскоокруглой или округлой формой плода и со средней массой 220-270 г. Для повышения транспортабельности томатов необходимо, чтобы плоды отличались высокой прочностью и характеризовались хорошей лежкостью. Урожайность гибрида томата должна быть более 30 кг/м2, а товарность - не менее 85%. Гибрид томата должен обладать следующим набором генов устойчивости в гетерозиготном состоянии: Ty3a, Mi1.2, Cf-9, а также в гомозиготном состоянии: Tm2a, I2, Ve. The article provides information on the study of the collection of F1 tomato hybrids (Solanum lycopersicumL.) of foreign breeding from various firms-originators recommended for cultivation in regions with a strong spread of tomato yellow leaf curl virus. All hybrids had a complex of economically valuable traits and a set of genes for resistance to the main diseases of tomato, including a new dangerous pathogen for the South of Russia with a maximum potential risk — the tomato yellow leaf curl virus (TYLCV). The studies were carried out in 2017-2018 in the Solanaceae Laboratory of LLC NIISOK and in the Molecular Diagnostics Laboratory of Plants of LLC Semenovod. A total of 34 F1 tomato hybrids were tested. The hybrids were assessed by a set of economically valuable traits. Molecular genetic analysis was also carried out for the presence and allelic state of the main resistance genes: Tomato mosaic virus (Tm2a), Fusarium wilt (I2), Werticillium wilt (Ve), Cladosporium fulvum (Cf9), Nematodes (Mi1.2), Tomato spotted wilt virus (Sw5), Tomato yellow leaf curl virus (Ty3a). It was found that all the analyzed tomato hybrids with the declared by seed originators resistance to yellow leaf curl virus were heterozygous for the Ty3a gene. Based on the conducted research and taking into account the market requirements, models of F1 tomato hybrids for protected ground for the South of Russia have been developed. A promising tomato hybrid should have an indeterminate growth type with shortened internodes (4.5-5 cm) and good foliage. Tomato fruits should have a uniform red color without green shoulders, with a flat-round or round shape of the fruit and with an average weight of 220-270 g. To increase the transportability of tomatoes, it is necessary that the fruits are highly firm and characterized by good shelf life. The yield of tomato hybrid should be more than 30 kg/m2, and marketability should be at least 85%. The tomato hybrid should have the following set of resistance genes in a heterozygous state: Ty3a, Mi1.2, Cf-9, and also in a homozygous state: Tm2a, I2, Ve.

Sensitivity Detection

The main objective of this study was to make sure whether randomly taken 12 samples were sensitive to abacavir. The genomic DNA from 12 blood sample were extracted by phenol chloroform DNA extraction method, extracted genomic DNA were amplified and sequenced, thereafter SNPs were detected. Every sample had shown the presence of normal base at SNP position. This study indicated, those randomly taken 12 patients were sensitive to abacavir, so they can consume abacavir if they get infected with HIV.
