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 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 (...

Chromosome studies in familial leukaemia.

The finding of an inherited chromosome abnormality (Chl) in several members of a family, including two who had developed chronic lymphocytic leukaemia (Gunz, Fitzgerald, and Adams, i962), led to the suggestion that this abnormality predisposed its carriers to the development of the disease, and that inherited cytogenetic abnormalities of this type might determine some instances of familial leuk...

Ecotoxicological studies on the pejerrey (Odontesthes bonariensis, Pisces atherinopsidae).

The pejerrey (Odontesthes bonariensis, Cuvier and Valenciennes, 1835) is an Atherinid fish characteristic of the Southern sector of the 'del Plata' basin (Bonetto and Castello, 1985). This species not only possess ecological relevance (it could represent the largest fish bio-mass, especially in low diversity euryhaline lakes; Baigún and Delfino, 2001), but also has regional socioeconomic releva...
