An HHMI scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture.

Arabidopsis thaliana, a small flowering mustard plant, normally reproduces sexually. But Jean Philippe Vielle-Calzada and his colleagues have show that silencing a protein called Argonaute 9 causes the plant to begin reproducing asexually instead. The blue shading shows the area involved in gamete formation that is disrupted when Argonaute 9 is silenced.

They can’t grow these seeds themselves because the very act of sexual reproduction erases many of those carefully selected traits. So year after year, farmers must purchase new supplies of specially-produced seeds.

This problem is sidestepped by some plants—such as dandelions and poplar trees—that reproduce asexually by essentially cloning themselves. Jean-Philippe Vielle-Calzada, a Howard Hughes Medical Institute (HHMI) international research scholar, wondered whether he could learn enough about the genetics of asexual reproduction to apply it to plants that produce sexually. In an advance online publication in Nature on March 7, 2010, Vielle-Calzada and his colleagues report that they have moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture.

The knowledge of sexual and asexual mode of reproduction be used in Applied Sciences such as in agriculture for example if we want to grow a rose plant then we can grow it by cutting it steam and planting it and so we are able to know this only if you have the knowledge of modes of reproduction .
