Seeds with extra genomes that alter this critical ratio undergo a process known as interploidy seed abortion due to defective endosperm development. RNA Pol IV is an enzyme specific to plant ...

This research demonstrates the existence of an unexplored step between pollen tube guidance and fertilization, where PTCs have a major role in seed development. In crops, such as rice, corn and wheat, ...

Hence, particularly in agriculture and horticulture, the development of polyploid plants ... this is one of the first studies that use "endosperm culture" -- an application of PTC techniques ...

Researchers in China have developed a genetic engineering approach capable of delivering many genes at once and used it to make rice endosperm--seed tissue that provides nutrients to the ...

Virtually all angiosperms have endosperm that is “triploid”, that is, it contains three copies of each chromosome: two from the mother and one from the father’s sperm. This triploid ...
