In angiosperms, pollen tube reception by the female gametophyte is required for sperm release and double fertilization. In Arabidopsis thaliana lorelei (lre) mutants, pollen tube reception fails in ...

miRNAs are small non-coding RNAs that regulate gene expression and influence key developmental processes. In plants, these molecules are produced through a multistep biogenesis pathway involving the ...

Like seeds, pollen loses most of its water during maturation, entering a state of suspended animation. This allows it to survive its journey from male to female organs of a flower, where it is ...

It cakes our cars in yellow powder every spring and taunts allergy sufferers for months on end, but pollen is more than just plant sperm. New research has determined when pollen comes of age and ...

Flow cytometry is a powerful analytical tool employed in several industries. This article will provide an overview of its use in the field of botany. Flow cytometry measures the chemical and physical ...

When different varieties of one plant species are crossed with each other, their hybrid offspring are often more robust and grow more quickly than their parents. However, in the next generation, this ...
