Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have ...

Pollination, essential to much of life on earth, requires the explosive death of the male pollen tube in the female ovule. In new research, scientists describe the genetic and regulatory factors that ...

Mae West said that anything worth doing is worth doing slowly. Plants would probably agree, if they could. Courtship in flowering plants begins when pollen lands on the receptive surface (stigma) of a ...

When a particle of plant pollen lands on a female flower, its journey is not done. The pollen, which typically contains two sperm cells and a sperm transport vehicle called the pollen tube cell, ...

Pollination is a key process in the life cycle of flowering plants (angiosperms). It typically involves a vector responsible for the transport which can be either biotic (animals) or abiotic: usually ...

Sand rock- cress (Arabidopsis arenosa) serves as a model for unravelling the mystery surrounding the sterility of newly formed polyploids. Most mammals and humans have a double set of chromosomes – ...
