Autonomous reproduction assurance in mirror-image flowers: Delayed self-pollination in Monochoria valida.
Pollination is a key process that allows plants to complete their sexual reproduction. Many different vectors such as animals, insects, wind, water etc., can transport pollen grains from the male (anther) to the female (stigma) organ. Here we describe a new mechanism to guarantee pollination in a perennial Monochoria species with mirror-image flowers, in which the perianth of enantiostylous flowers twist helically after the flower closes to ensure pollination. If the flower is left-handed (as viewed from the plant), the perianth will twist counterclockwise and vice versa. This results in the anthers of the large stamen coming into contact with the stigmas to complete pollination without the aid of any pollinating agent or medium. This pollination mechanism represents an autonomous delayed self-pollination, that safeguards reproductive success when normal pollinator insects are scarce.
