Inbreeding depression and outcrossing rate in endangered autotetraploid plant Aster kantoensis (Asteraceae)

Article Abstract:

A study was conducted to investigate inbreeding depression in a population of Aster kantoensis, an endangered autotetraploidplant. The survivorship of the progeny and the number of flowering individuals per progeny array were analyzed. Results showed that the number of flowers per reproductive individual was greater in the outcrossed progeny after two years. Findings also indicated the need for more studies on seed migration to determine the population and genetic dynamics of A. kantoensis.

Tetrasomic segregation of allozyme markers in an endangered plant, Aster kantoensis

Article Abstract:

The tetrasomic segregation of four allozyme markers in Aster kantoensis suggests that the plant has a tetrasomic mode of inheritance. The progeny segregation ratios fit tetrasomic rather than digenic-disomic inheritance. The results suggest an autotetraploid origin of A. kantoensis. No chromatid segregation is observed in the crossing experiments of A. kantoensis, an endangered plant growing in the floodplains of central Japan.
