Subjects addressed include: endosperm development, epigenetic control of seed gene imprinting, apomixis, high-throughput genetic dissection of seed dormancy, improving grain quality, legume seed and cotton fiber genomics, genomic changes in response to 110 cycles of selection for seed protein and oil concentration in maize, and the machine vision for seed phenomics.

Other plants, especially weeds such as hawkweed and dandelions, can produce true seeds that are clones of themselves without sexual reproduction -- a still poorly understood process called apomixis.
This reduction in parental legacy has been termed the cost of meiosis (Williams, 1975) and can be avoided by selfing via self-fertilization, the fusion of gametes from the same individual; by automixis, the activation of a meiotically divided cell (see Mogie, 1986); or by apomixis, a process particular to angiosperms and gymnosperms where seeds form without the need of meiosis and fertilization (see Bicknell and Koltunow, 2004).
