The structure and function of microfilaments (MFs) and microtubules (MTs) are described in the binucleate/bicellular pollen tubes of Nicotiana tabacum. In this species the pollen grain and tube are formed of two
What is Pollen Grain? What Does Pollen Contain? Function of a Pollen Cell Lesson Summary FAQs Activities What textures can pollen grains have? Pollen grains can have a variety of textures, including smooth, net-like, bumpy, and parallel striations. These textures can be used to help identif...

Pollen grains are produced by the male structure of the flower and pollen grains are produced in, specifically the anther of flower-bearing plants (angiosperms) or in the microsporangia of gymnosperms. The structure of pollen grain assists with their function. The function of the pollen grain ...

and piezo is also localized to endomembranes36,37. In addition, MCA1 and MCA2 function as Ca2+-permeable mechanosensitive channels in roots38. Structural analyses of OSCAs have shown the importance of lipid interactions and conformational changes in their activation, and some OSCAs can be activate...
Although many allergen homologs have been predicted from species such as wheat and timothy grass, fundamental aspects such as the evolution and function of plant pollen allergens remain largely unclear. With the development of genetic engineering and genomics, more primary sequences, functions and ...
