Cytological Studies on <i>Luzula</i> Chromosome. II Pachytene Chromosome of <i>Luzula Purpurea</i>

CHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...

Integrating genetic linkage maps with pachytene chromosome structure in maize.

Genetic linkage maps reveal the order of markers based on the frequency of recombination between markers during meiosis. Because the rate of recombination varies along chromosomes, it has been difficult to relate linkage maps to chromosome structure. Here we use cytological maps of crossing over based on recombination nodules (RNs) to predict the physical position of genetic markers on each of ...
