In this paper, a new foldable structure has been studied and designed drawing inspiration from the structure of a pollen grain of angiosperm. This structure is made by two materials: a more rigid upper part which works only in compression and a less rigid lower part which undergoes tensile ...

Boric acid stimulates the plasma membrane H+‐ATPase of ungerminated lily pollen grains The stimulation of the plasma membrane (PM) H + ‐ATPase by boric acid was studied on a microsomal fraction (MF) obtained from ungerminated, boron‐depende... G Obermeyer,R Kriechbaumer,D Strasser,... ...
The first structure of a clinically relevant inhalant allergen to be determined was Bet v 1, a pathogenesis-associated protein from birch pollen (Gajhede et al., 1996; Figure 2). Natural Bet v 1 is composed of a mixture of at least 18 variants, from which Bet v 1.0101 is the most abu...

In treated plants, numbers of pollen grains and also amount of fertile pollen grains were decreased in each anther significantly. Exine was not formed in some case of plants that treated by different acid solutions. Degradation of tapetum cells was take later in treated plants than control ones....

Also many vesicles released out from polluted pollen grains. SDS-PAGE showed that protein bands of polluted and non-polluted pollen grains are not different significantly, but in polluted pollen grains decrease protein content, as a result of air pollution that cause releasing of pollen proteins....
