Seed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملIncreased Oxygen Bioavailability Improved Vigor and Germination of Aged Vegetable Seeds
Large and/or aged seeds are prone to hypoxic conditions during germination. Germination of selected vegetable seeds including corn (Zea mays L.), squash (Cucurbita pepo L.), and tomato (Solanum lycopersicum L.) was studied in water with different concentrations of hydrogen peroxide (H2O2) solution ranging from 0, 0.06% to 3.0% (v/v) or in aeroponics, all with 0.5 mM CaSO4. Imbibition, oxygen co...
متن کاملDependence of Seed Vigor during Germination on Carbohydrate Source in Endosperm Mutants of Maize.
Differences in seed vigor of four genotypes of maize (Zea mays L.), brittle-1 (bt1), shrunken-2 (sh2), sugary (su), and normal, in an isogenic background, were investigated. Excised whole embryos and axes were grown on Murashige and Skoog (MS) media containing various carbohydrate sources. Of the four genotypes examined, sh2 seeds had the lowest vigor, especially under germination stress condit...
متن کاملQTLs for Seed Vigor-Related Traits Identified in Maize Seeds Germinated under Artificial Aging Conditions
High seed vigor is important for agricultural production due to the associated potential for increased growth and productivity. However, a better understanding of the underlying molecular mechanisms is required because the genetic basis for seed vigor remains unknown. We used single-nucleotide polymorphism (SNP) markers to map quantitative trait loci (QTLs) for four seed vigor traits in two con...
متن کاملChanges in Level and Activity of Phospholipid Transfer Protein during Maturation and Germination of Maize Seeds.
The variations of the amounts of phospholipid transfer proteins (PLTP), determined by ELISA and immunoblotting methods, were followed during the maturation and germination of maize (Zea mays L.) seeds. Changes of the amounts of PLTP occur during seed maturation. The levels of PLTP, low in the first 3 weeks after fecondation, strongly raised 3 to 5 weeks after, then reached and maintained a high...
