In studies of signals between plant embryos and their endosperm, researchers at the Max Planck Institute for Plant Breeding Research and the University of Cologne have isolated a mutant where there is ...

Improving grain quality is one of the important objectives in cereal breeding (Sadimantara et al, 1997; Mazur et al, 1999; Tan et al, 1999; Wang et al, 2001). Many grain quality traits, such as ...

A large portion of plant seeds is endosperm. It has the important task of nourishing the plant embryo during the early stages of its development. In flowering plants, there is a complicated ...

Plants lack a germline, express many genes in the haploid phase of the life cycle and have a flexible developmental plan. These features allow stringent selection in the haploid phase against ...

The endosperm, the tissue surrounding the plant embryo in the seed, has long been perceived as a nourishing tissue that is abandoned once the transition to the seedling is complete. A Swiss team, led ...

The ovules of flowering plants are housed in a carpel. Pollen lands on the flower's stigma and forms a pollen tube. It then uses each one of its two sperm cells to fertilise the egg cell, from which ...
