Cariotipos de especies sudamericanas de Serjania (Sapindaceae, Paullinieae)

Abstract

Se han estudiado los cromosomas mitóticos de quince especies de Serjania Mill., con 2n = 24, de América del Sur. Los resultados incluyen los primeros recuentos de S. paludosa Cambess. y S. setigera Radlk. Fueron analizados los cariotipos de todas las especies, trece de ellos se describen por primera vez. Aunque no ha habido ningún cambio en el número de cromosomas durante la evolución de Serjania y los cariotipos muestran un moderado grado de asimetría, hay una considerable variabilidad en tamaño de los cromosomas entre las especies. El análisis comparativo de las especies de la misma sección muestra diferencias en la longitud de los cromosomas y la constitución cariotípica. Esto fue también evidente en las dos accesiones de S. laruotteana Cambess. y S. meridionalis Cambess. La variabilidad cariotípica observada en Serjania sería el resultado de reordenamientos cromosómicos estructurales y/o la adición de material genético.
