Optional elements in the chloroplast DNAs of chlamydomonas eugametos and C. moewusii: unidirectional gene conversion and co-conversion of adjacent markers in high-viability crossses.

Abstract excerpt

Unlike most polymorphic markers in the Chlamydomonas eugametos and Chlamydomonas moewusii chloroplast DNAs (cpDNAs), the C. moewusii 6- and 21-kb extra sequences and the C. eugametos-specific CeLSU small middle dot 5 intron are transmitted to all of the few viable progeny in reciprocal crosses between the two green algae. To determine whether this unidirectional transmission pattern is due to gene conversion or...
