Plant reproduction

Plant reproduction is the production of new individuals from one or more parent plants. This can be accomplished by sexual or asexual means.

    Sporopollenin, which encapsulates gametes in spore and pollen grains, is probably the most chemically inert biopolymer. This inertness is essential for gamete protection, but also hinders the elucidation of sporopollenin molecular structure. Now, the macromolecular network forming sporopollenin is described in unprecedented detail.

    Seasonal control of flowering is a dramatic example of interactions between genes and environment, and is mostly studied in growth chambers. However, switching from natural settings to artificial conditions affects phenotypes. More natural responses in cabinets can be obtained by only modifying a few environmental parameters.

    Biennial plants require exposure to the cold of winter to overcome a block to flowering in the spring. The molecular role of FRIGIDA, a key component of the system that establishes the cold requirement in Arabidopsis, is to assemble a protein super-complex that promotes expression of a flowering repressor in the autumn.

    In autogamous plants, self-pollination is ensured by a timely opening of anthers (dehiscence) and release of mature pollen grains. Auxin plays a paramount role in controlling the correct timing of anther dehiscence. Now, a molecular switch that allows the timely change in auxin level in rice anthers has been unveiled.
