  • Since resources are limited, the number of existing ovules would be greater than the number of seeds the maternal plant can support, leading to competition for resources. (wikipedia.org)
  • Endosperm is the tissue that is formed from double fertilization in flowering plant seeds, the process whereby a sperm nucleus fuses with the binucleate central cell. (springeropen.com)
  • Seeds of approximately 70% flowering plants have endosperm cells (Brown and Lemmon 2007 ), most of them are triploidy. (springeropen.com)
  • The arrangement of ovarian vascular bundles, which transport nutrients to ovules, has been proposed as a potential influence on position-dependent probabilities of abortion. (wikipedia.org)
  • These parasitic species show variation in the invasiveness of endophytic tissue of haustorium into the host vascular tissue. (pakbs.org)
  • Selective embryo abortion (also known as selective seed abortion and selective ovule abortion ), is a form of non-random, premature termination of embryonic development in plants. (wikipedia.org)
  • In contrast, the hypothesis of female choice states that selective embryo abortion may be driven by the maternal plant, which identifies and aborts inferior embryos. (wikipedia.org)
  • In general, there is significant overlap in gene expression between embryo development and plant maturation. (wikipedia.org)
  • Selective embryo abortion may therefore act on traits affecting plant survival and fitness following germination. (wikipedia.org)
  • Monocots have one cotyledon, which is a part of the plant embryo within the seed of the plant where food is stored until the plant produces its leaves. (meganhardenfitness.com)
