Explore the ovule of a flower. See the ovule definition and discover where the ovules are stored. Understand the ovule function in a flower and see its components. What is the Ovule of a Flower? Angiosperms, or flowering plants, frequently produce flowers that are ''hermaphroditic'' or ''bi...
The pistil, made up of the basal ovary that bears the ovules, elongated style, and terminal stigma, is the female reproductive organ of the flower. The female gametophyte, designated as the embryo sac, is located inside the ovule. The pistil is the recipient of the pollen and a conduit ...
Understand what the male part of a flower is. Learn about the male reproductive part of the flower and the reproductive organ of the plant in...
The function of MADS-box genes in flower and fruit development has been uncovered at a rapid pace over the past decade. Evolutionary biologists can now analyse the expression pattern of MADS-box genes during the development of different plant species, and study the homology of body parts and th...
Beijing 100871, China; 2The National Plant Gene Research Center (Beijing), Beijing 100101, China As a cell cycle regulator, the Myb-related CDC5 protein was reported to be essential for the G2 phase of the cell cycle in yeast and animals, but little is known about its function in plants...
The flower produces two kinds of gametophytes, male and female. The female gametophyte arises from a cell within theovule, a small structure within the ovary of the flower. The ovary is a larger structure within the flower that contains and protects usually many ovules. Flowering plants are un...
To this end, cytological sectioning of ovules was carried out in both wild type and the double mutant. Megaspore mother cells and functional megaspores were enclosed by integuments indistinguishable between wild type and Clbbm/Clplt2-1 double mutant (Fig. 5, A, B, E and F). At stage ...
and another ~30 flowers were selected as controls. Pollen grains used for hand-pollination were taken from newly opened flowers and were sufficient to fertilize all the ovules in a flower. There was more than 10 m between pollen donors and hand-pollinated flowers to ensure cross-pollination....
Obvious movements of plant organs have fascinated scientists for a long time. They have been studied extensively, but few behavioural studies to date have dealt with them, and hardly anything is known about their evolution. Here, we present a large exper
Here we isolate the SUP ortholog in Cucumis sativus L (CsSUP), a monoecious vegetable. CsSUP is predominantly expressed in female specific organs: the female flower buds and ovules. Ectopic expression of CsSUP in Arabidopsis can partially complement the fruit developmen...
