Comparative analysis of the chemical composition and size of starch granules in grain between diploid and tetraploid sweetcorn cultivars

Труды по прикладной ботанике, генетике и селекции, 2021
Background. Improving the taste and nutritional value of sweetcorn using genetic selection techniques is an important trend. The tetraploid sugary maize cultivar ‘Baksanskaya sakharnaya’ (k-23426) has a number of advantages in terms of taste and ...

Metabolic Disturbance Induced by the Embryo Contributes to the Formation of Chalky Endosperm of a Notched-Belly Rice Mutant

Frontiers in Plant Science, 2022
Grain chalkiness is a key quality trait of the rice grain, whereas its underlying mechanism is still not thoroughly understood because of the complex genetic and environmental interactions.

Starch Biosynthesis in Crop Plants

Agronomy, 2018
Starch is a water-insoluble polyglucan synthesized inside the plastids of plant tissues to provide a store of carbohydrate. Starch harvested from plant storage organs has probably represented the major source of calories for the human diet since before ...

Variations of endoreduplication and its potential contribution to endosperm development in rice (Oryza sativa L.)

Plant Production Science, 2019
Endoreduplication is the phenomenon by which cells increase their ploidy. Endoreduplication is initiated by the transition from the mitotic cell cycle to the endocycle, in which DNA replication occurs without a subsequent chromosome separation and ...

Genetic and environmental manipulation of Arabidopsis hybridization barriers uncovers antagonistic functions in endosperm cellularization

Frontiers in Plant Science, 2023
Speciation involves reproductive isolation, which can occur by hybridization barriers acting in the endosperm of the developing seed. The nuclear endosperm is a nutrient sink, accumulating sugars from surrounding tissues, and undergoes coordinated ...

Changes in concentration of protein and nucleic acids in the endosperm during ovule development in Clivia miniata

Acta Societatis Botanicorum Poloniae, 2014
Changes of protein and nucleic acid concentrations in micropylar and chalazal parts of the endosperm during exponential and stationary phases of embryo growth (Clivia miniata Regel) were examined. The following facts were established: 1.

Embryology in Helosis cayennensis (Balanophoraceae): Structure of Female Flowers, Fruit, Endosperm and Embryo

Plants, 2019
Helosis cayennensis (Balanophoraceae s.str.) is a holoparasite characterised by aberrant vegetative bodies and tiny, reduced unisexual flowers. Here, we analysed the development of female flowers to elucidate their morpho-anatomy and the historical ...

Determining the Nutritional Potential of Ancient Wheat Species: A Closer Look at Starch and Protein Digestibility, and Phenolic Acid Content

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The recent trend towards healthy food choices and sustainable agriculture has revived interest in underutilized wheat species such as emmer, einkorn, and spelt. Given these developments, the objective of the study was to compare the differences in chemical composition and digestibility characteristics among ...
