Scientists have succeeded in discovering AMOR, a sugar chain that increases the fertilization efficiency in plants. AMOR was found to be responsible for activating pollen tubes to lead to ...

Pollen tube guidance towards the ovule is an important step for fertilization in flowering plants. In order for this to happen, a pollen tube attractant peptide LURE guides the pollen tube precisely ...

Researchers found that attractant peptides released by female tissues initiate rapid depolymerization and repolymerization of actin at the leading edge of the pollen tube tip, steering its direction ...

During compatible pollination of the angiosperms, pollen tubes grow in the pistil transmitting tract (TT) and are guided to the ovule for fertilization. Lily (Lilium longiflorum) stigma/style Cys-rich ...

Flowering seed plants (angiosperms) have evolved unique ways to protect their gametes from pathogen attack and from drying out. The female gametes (egg and central cell) are deeply embedded in the ...

This story was originally published by Yale Environment 360 and is reproduced here as part of the Climate Desk collaboration. Last June, Aaron Flansburg felt the temperature spike and knew what that ...

In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...
