Other claims from this paper (7)
- Observation In maize, heterochromatic knobs visible at pachynema were coincident with C-bands and 180-bp FISH signals on somatic chromosomes.
- Observation Most heterochromatic knobs in maize were large.
- Observation Presence of some knobs varied among maize lines.
- Observation Small 180-bp knob signals were invariant on the short arms of maize chromosomes 1, 6 and 9.
- Observation The subtelomeric 4-12-1 signal in maize was invariant and useful for identifying some chromosomes.
- Observation The centromere location of maize chromosomes 2 and 4 differed from previous reports on standard maize lines.
- Observation In a maize hybrid, the homologues were fully synapsed at pachytene, including the 5S rDNA and CentC sites on chromosome 2 and the Cent4 and subtelomeric 4-12-1 sites on chromosome 4.
