These are the green leafy structures found around the base of the flower. The corolla, also known as the petals, represent modified leaves that are often colorful in order to attract pollinators like bees and hummingbirds. The androecium, also referred to as the stamen, contains the male ...
The senescence of carnation ( Dianthus caryophyllus L.) flower petals is associated with increased synthesis of the phytohormone ethylene. This ethylene serves to initiate and regulate the processes of programmed organ death. We have isolated and cloned mRNAs which encode the ethylene biosynthetic ...
Floral homeotic B-function genes are involved in specifying the identity of petals and stamens during flower development in higher eudicotyledonous plants... T Münster,LU Wingen,W Faigl,... - 《Gene》 被引量: 262发表: 2001年 Flower Evolution: The Origin and Subsequent Diversification of the...
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...
Among these mysteries is the differentiation of four distinct organ types (sepals, petals, stamens and carpels), each of which may be a modified leaf. A landmark accomplishment in plant developmental biology is the ABC model of flower organ identity. This simple model provides a conceptual ...

Inside the sepals and petals are the male and female flower parts. Does every flower have a sepal? Most flowering plants have sepals, but grasses are a type of flowering plant that does not have sepals but has a different kind of structure instead. Where is the sepal in a flower?
Lynn has a BS and MS in biology and has taught many college biology courses. Flowers are reproductive structures of angiosperms, or flowering plants. The four main parts of flowers are sepals, petals, stamens, and carpels. The stamens are male reproductive structures that produce pollen. The...
The family Ranunculaceae is an excellent system for the study of pseudonectary development and evolution, for three reasons. First, pseudonectaries, especially those that are located on petals, have been documented in at least four genera (i.e., Nigella, Trollius, Eranthis, and Xanthorhiza),...
