Isozyme variation in Californian and Turkish populations of the colonizing species Trifolium hirtum
Article Abstract:
Rsearch was conducted on isozyme variation in trifolium hirtum (rose clover) populations from California and Turkey. Californian rose clovers were imported from Turkey in 1944. Results showed that the intercontinental movement of the species did not reduce genetic diversity at the isozyme loci. Results also showed a difference between Californian and Turkish rose clover mating systems. Turkish populations were found to have an average genetic distance four times larger than their Californian counterparts. On the other hand, multilocus genotypes abounded more in the Californian species.

Inheritance of growth habit-related attributes in red clover
Article Abstract:
There are two types of red clover: prostrate and erect. The first type is persistent, with small leaves and creeping thin stems, while the second type has large leaves, thick stems and low persistence. Prostrateness of the erect type may be advantageous in the commercial market. A new study investigates the function and number of genes controlling prostrateness and stem thickness in red clover. Evidence suggests that dominance X dominance epistasis controls prostrateness and additive X additive epistasis controls stem thickness. These attributes are oligogenic.

Segregation distortion at isozyme locus Lap-1 in Schlumbergera (Cactaceae) is caused by linkage with the gametophytic self-incompatibility (S) locus
Article Abstract:
Linkage between leucine aminopeptidase-1 (LAP-1) and the S locus is the reason why semicompatible crosses of Schlumbergera often produce progeny with skewed segregation ratios at LAP-1, according to research into the inheritance of LAP, phosphoglucomutase (PGM) and shikimate dehydrogenase (SKD) isozymes in Schlumbergera truncata and S. x buckleyi (Cactaceae). Most of the F2 and BC1 families with distorted segregation ratios at LAP-1 showed normal segregation ratios at SKD-1 and PGM-1, thus supporting the view that there is a link between LAP-1 and S.
