    Notes: Summary In three clones of Petunia hybrida with different incompatibility genes, phytic acid is detected exclusively in pollen, stigma and style. These are all parts of the floral structure involved in the incompatibility reaction. Phytase activity was detected in these tissues as well as in the ovary. The level of phytic acid and phytase activity varied between clones with different S alleles. This difference was most evident in stigma and style. The pattern of phytic acid breakdown following pollination depends on whether pollen and style form a compatible or incompatible combination. Incompatible pollination results in a higher rate of degradation. Consideration is given to the relationship between breakdown of phytic acid to myo-inositol and cell wall thickening and plug formation, which occurs to a greater extent in the incompatible combination.

    Self-incompatibility alleles control a low molecular weight, basic protein in pistils of Petunia hybrida (1986)

    Notes: Summary Proteins extracted from the pistils of several clones of Petunia hybrida carrying differing pairs of S alleles were examined by gel electrophoresis. The major protein of pistils, a basic glycoprotein of relatively low molecular weight, showed properties which varied in a simple manner with the S genotype. For each S allele we were able to assign a specific molecular weight (ranging from 27,000 to 33,000) and isoelectric point (in the range 8.3 to 8.7) for this putative S protein. Pistils homozygous at the S locus showed only one major protein on two-dimensional gel electrophoresis, while pistils from plants heterozygous at the S locus showed two. No evidence was obtained for the presence of this putative S protein in pollen extracts.

    Inheritance of resistance to Fusarium wilt in Indian lentil germplasm (Lens culinaris Medik.) (1990)

    Notes: Summary Three lentil genotypes resistant to Fusarium oxysporum f.sp. lentis viz. Pant L 234, JL 446 and LP 286 were crossed with two susceptible ones. The hybrid plants were all resistant in the eight crosses evaluated. Segregation pattern for wilt reaction in F2, BC(P1), BC(P2) and F3 generations in field and glasshouse conditions indicated that resistance to Fusarium wilt is under the control of two dominant duplicate genes in Pant L 234 and two independent dominant genes with complementary effects in JL 446 and LP 286. A third dominant gene complementary to the dominant genes in JL 446 and LP 286 is present in two susceptible lines. Allelic tests suggest the presence of five independently segregating genes for resistance. Duplicate dominant genes in Pant L 234 are non-allelic to two dominant genes with complementary effects in LP 286 and JL 446 and the third gene complementary to the two genes in JL 446 and LP 286 in susceptible lines JL 641 and L 9–12. Gene symbols among parental genotypes have been designated.
