EU Citizens in the European Public Sphereand McLean (1990) pointed out that the concentrations of actin in any plant tissue are lower than they are even in animal cytoplasmic tissues. However, we found that pollen is an excellent source of actin in higher plants in which the quantity of actin is sufficient to do biochemical investigation.

Roberto Scaramuzzino,Gabriella Scaramuzzinoe rejection of incompatible pollen tubes (8–16 hours after self-pollination) is accompanied by higher sucrose and fructose but not glucose levels. Hence compatible pollen tubes absorb more carbohydrates from the style tissues than incompatible tubes. Glucose produces callose deposited in the tubes, particularly in the incompatible pollen tubes.

Molecular Genetics of Self-incompatibility in,diploid genome of the female tissue of the sporophyte, the pistil. In incompatible matings, as is the case when the S-allele carried by the haploid pollen matches either of the S-alleles present in the diploid style, pollen tube growth is arrested within the transmitting tract (Figure 1).

ctors, as pointed out with great foresight by one of the driving forces in the field, H.E Linskens (Linskens 1964): most of the food consumed by humans takes the form of plant reproductive parts, and molecular biology now provides pow erful tools for investigating and manipulating plant reproductiv

Allergens are environmental antigens which induce the formation of specific IgE, and bind specifically to IgE on the surface of epithelial mast cells. This triggers the mast cells to release the mediators of allergy.

Christoph Kirtzel,Astrid Lorenztilization is blocked when the S-allele carried by the pollen matches one of the two alleles carried by the pistil. Incompatible pollen initially germinates and the tube penetrates the stigma, but its growth is subsequently inhibited before reaching half the length of the style. The tips of incompatible pollen tubes usually swell and burst open.
