Economic considerations have stimulated studies of gene flow as a function of distance, breeding system, pollinating agent, and planting design in numerous domestic plants. Only during the past two decades have a large body of plant evolutionists become interested in information accruing from these ...
Post-zygotic genetic incompatibility can ensue when hybridization brings together gene products that no longer function properly together in the same genome, thus reducing gene flow among incompatible genotypes. In plants, numerous forms of postzygotic genetic incompatibilities exist, including hybrid steril...
Gene flow in agricultural crops is important for risk assessment of genetically modified (GM) crops, particularly in countries with a large informal agricultural sector of subsistence cultivation. We present a pollen flow model for maize (Zea mays), a ma
In the last few decades, a large research input has been geared up to develop and exploit a number of different techniques aiming to produce plants with improved resistance to biotic and abiotic stresses, and seeds with enhanced nutritional values. Genet
Plants mainly depend on wind, insects, gravity, and other ways to achieve gene flow by the migration of seeds, pollen, spores, and asexual reproductive organs. Mountains and rivers function as natural geographical barriers affecting gene flow in plants [6,7,8]. Moreover, human disturbances, ...
These results provide a good starting point for further experimental analysis of plant seed-specific promoters and our methodology can be used to unravel more transcriptional regulatory mechanisms in plants and other eukaryotes.Background Designing expression cassettes allowing a precise control of where, ...
The gene coexpression clusters and putative regulatory elements presented here provide a useful resource for further experimental characterization of protein interactions and regulatory networks in this process. Background Seed storage reserves accumulated during embryogenesis in higher plants are crucial for ...
by DR5: VENUS visualization, lack of SlSoPIN1a function in e-2 causes a widening of the auxin flow pathway during leaf initiation, early leaf and sympodial meristem development, likely contributing to aberrant leaf morphology, vasculature, inflorescence, and flower defects found in e-2 plants. ...
The physical seed dormancy (PY) variation could be useful depending on the specific context. High PY is desirable for ley farming systems, while low PY is needed to prevent weediness in subsequent crop rotations. Gene flow between cultivated and naturalized populations has important ecological and ...
Plants adapted to diverse environments on Earth throughout their evolutionary history, and developed mechanisms to thrive in a variety of terrestrial habitats. When plants are grown in the novel environment of spaceflight aboard the International Space S
