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...

Chromosome studies in the genus Jatropha L

The inflorescences of ten species of the genus Jatropha were fixed in Cornoy’s fluid (6:3:1). Acetocarmine stain (2%) was used for staining the pollen mother cells. Seven species exhibited 11 bivalents and 2n =22 and x=11. But the two other species, J.villosa var. villosa and J.villosa var. ramnadensis showed only 10 bivalents and 2n number of 20 chromosomes and x=10. The study concluded the oc...

CHROMOSOME STUDIES IN ARABIDOPSIS THALIANAl

HE advantages of using Arabidopsis, a small crucifer, for studies of mutation Tand other genetic problems were pointed out by G. P. R ~ D E I (1962). His establishment of five linkage groups ( R~~DEI , private communication) and the occurrence of certain aberrant mutants made a study of Arabidopsis chromosomes desirable. The following is a report on the cytology of normal Arabidopsis thaliana (...
