Transfer of Anthocyanin Accumulating and Genes from the Transgenic Tomato Micro-Tom Cultivar to Moneymaker Cultivar by Conventional Breeding. | LitMetric
and anthocyanin accumulation genes were subjected to bioinformatics analysis. Delila protein has 56-69% similarity with different anthocyanin-rich plants, while Rosea1 protein has 83-87% with anthocyanin-rich plant proteins. This study aimed at transferring and genes from the transgenic Micro-tom tomato cultivar to the Moneymaker tomato cultivar using traditional breeding for enhancing their fruit anthocyanin content. Results of all produced F1 plants of manual hybridization between both cultivars were consistent with the Mendelian inheritance hypothesis. Plants of F2 populations showed a 3:1 Mendelian segregation proportion (75% of plants have anthocyanin pigmentation). Seeds of F2 were individually cultured to get four homozygous lines with anthocyanin accumulation in fruits. The total anthocyanin in the anthocyanin-enriched inbred fruit (3 g/kg DM) represented a relative increase of about 131% of the parent level. The total phenolic compounds in inbred tomato fruits were 54.9 mg/100 g DM referring to a relative increase of about 51% of the respective parent plant. The antioxidant activity of inbred fruit at maturity (m) was 83.5% compared with 91% for TBHQ. The inbred (m) tomato fruit extract reduced the growth of G bacteria G bacteria by 99% and 95%, respectively.
Arbuscular mycorrhiza (AM) represents a symbiotic mutualistic association between most land plants and fungi. AM fungi develops specialized intraradical and highly branched structures, called arbuscules, where bidirectional exchange of nutrients between plant and fungi partners occurs, improving plant growth and fitness. Transcriptional reprogramming and hormonal regulation are necessary for the formation of the arbuscules.
Amaranth is an ancient crop of the family Amaranthaceae, but it is fairly new to Russia. Its seeds and leaf biomass contain a high-quality gluten-free protein, fatty acids, squalene (a polyunsaturated hydrocarbon), flavonoids, vitamins, and minerals. A comprehensive study of amaranth, enhancement of its breeding, and development of new cultivars will contribute to food quality improvement through the use of plant raw materials enriched for wholesome and highly nutritious components.
Background: Drought is one of main critical factors that limits sugarcane productivity and juice quality in tropical regions. The unprecedented changes in climate such as monsoon failure, increase in temperature and other factors warrant the need for development of stress tolerant cultivars to sustain sugar production. Plant Nuclear factor (NF-Y) is one of the major classes of transcription factors that have a major role in plant development and abiotic stress response.
A diet rich in anthocyanins can benefit human health against a broad spectrum of human diseases due to the high antioxidant activities of anthocyanins. Enrichment of anthocyanins in the starchy endosperm of rice is an effective solution to provide nutritional food in human diets. However, previous attempts failed to engineer anthocyanin biosynthesis in the rice endosperm by transgenic expression of rice endogenous genes.
Maize ( L.) is a major food and feed crop and an important raw material for energy, chemicals, and livestock. The NF-Y family of transcription factors in maize plays a crucial role in the regulation of plant development and response to environmental stress.
