New insights on the transcriptional regulation of seed germination

Seeds remain in a dormant state, waiting for the right environmental conditions to germinate, thus increasing the probability of fragile seedling survival. The transition from a dry seed to a vegetative seedling is an irreversible ...

Targeting seed microbes to improve seed resilience

Fonio (Digitaria exilis), a type of millet, is the oldest indigenous crop in West Africa and one of the fastest-maturing cereals. Despite its low yield, the combination of quick maturation and drought tolerance and its ability ...

How a wayside weed builds up explosive force to hurl seeds

Hairy bittercress is one of those plants that hurl their seeds in all directions to spread them effectively. A research team has now discovered that to do this, the plant uses a previously unknown mechanism that makes the ...

A seed ( /ˈsiːd/ (help·info)), referred to as a kernel in some plants, is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes the process of reproduction in seed plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule.

Seeds have been an important development in the reproduction and spread of flowering plants, relative to more primitive plants like mosses, ferns and liverworts, which do not have seeds and use other means to propagate themselves. This can be seen by the success of seed plants (both gymnosperms and angiosperms) in dominating biological niches on land, from forests to grasslands both in hot and cold climates.

The term seed also has a general meaning that predates the above — anything that can be sown i.e. "seed" potatoes, "seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds", what is sown is the seed enclosed in a shell or hull, and the potato is a tuber.
