● It is only in recent years that botanists have been able to `color{Violet}"identify"` some of the pollen and pistil components and the `color{Violet}"interactions"` leading to the `color{Violet}"recognition"`, followed by `color{Violet}"acceptance or rejection"`.
● Following `color{Violet}"compatible pollination"`, the pollen grain `color{Violet}"germinates on the stigma"` to produce a pollen tube through one of the germ pores.
●The contents of the pollen grain move into the pollen tube.
● Pollen tube grows through the `color{Violet}"tissues of the stigma and style"` and reaches the ovary.
● In some plants, pollen grains are shed at `color{Violet}"two-celled condition"` (a vegetative cell and a generative cell).
● In such plants, the `color{Violet}"generative cell divides"` and forms the two `color{Violet}"male gametes"` during the `color{Violet}"growth"` of pollen tube in the stigma.
● In plants which shed pollen in the `color{Violet}"three-celled condition"`, pollen tubes carry the two male gametes from the `color{Violet}"beginning"`.
● Pollen tube, after reaching the ovary, `color{Violet}"enters"` the ovule through the `color{Violet}"micropyle"` and then enters one of the `color{Violet}"synergids"` through the `color{Violet}"filiform apparatus"`.
● Many recent studies have shown that `color{Violet}"filiform apparatus"` present at the micropylar part of the synergids `color{Violet}"guides the entry"` of pollen tube.
● All these events–from `color{Violet}"pollen deposition"` on the stigma until pollen tubes `color{Violet}"enter the ovule"`–are together referred to as `color{Violet}" Pollen-pistil interaction"`.
● Pollen-pistil interaction is a `color{Violet}"dynamic process"` involving pollen `color{Violet}"recognition"` followed by `color{Violet}"promotion or inhibition"` of the pollen.
● The knowledge gained in this area would help the plant breeder in `color{Violet}"manipulating pollen-pistil interaction"`, even in incompatible pollinations, to get `color{Violet}"desired hybrids"`.
