The damage to the plant is relatively localized, although diseased corn plants are more susceptible to stalk rot than are healthy plants. [2] In conditions with high humidity, the fungus will produce new spores at the leaf surface, which are spread by rain or wind through the crop and create cycles of secondary infection. [ 5 ]
The absence of a gene found only in plants with Texas male sterile cytoplasm is the reason for this resistance. [1] Corn plants with T-cms cytoplasm have maternally inherited the gene T-urf 13, which encodes for a protein component of the inner mitochondrial membrane. T-toxin acts on this portion of the mitochondria. [4]
Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods. [ 1 ] Micropropagation is used to multiply a wide variety of plants, such as those that have been genetically modified or bred through conventional plant breeding methods.
Joseph Gottlieb Kölreuter was the first to document male sterility in plants. In the 18th century , he reported on anther abortion within species and specific hybrids. Cytoplasmic male sterility (CMS) is mostly found in angiosperms and has been identified in more than 140 angiosperm species.
The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds. The regeneration of whole plants from plant cells that have been genetically modified. The production of plants in sterile containers allows them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens.
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
A natural process often called "corn sweat" worsened a heat dome in the Midwest this week by fueling high humidity levels.
Detasseling corn plants from one variety in a field where two varieties are planted. The male flowers are removed so that all seeds are hybrids sired from the second variety. "Open pollination" and "open pollinated" refer to a variety of concepts in the context of the sexual reproduction of plants. Generally speaking, the term refers to plants ...
