Induction of tetraploid derivatives of maize inbred lines by nitrous oxide gas treatment

Article Abstract:

Induction of autotetraploid lines from elite inbred lines is valuable for investigating gene dosage effects on the molecular level. Twelve inbred lines were treated with nitrous oxide gas for 20 h at either 800 or 900 kPa pressures, 30 or 36 h after pollination which showed that although tetraploid or tetraploid class aneuploid plants from 9 of 12 inbreds tested were successfully generated, only six genotypes produced progenies.

Salmon silk genes contribute to the elucidation of the flavone pathway in maize (Zea mays L.)

Article Abstract:

The order of the undefined steps in the synthesis of the flavone maysin in maize silks is established. Findings established the order of intermediates in the late steps of maysin synthesis as luteolin->isooreintin->rhamnosylisoorietin->maysin.

Spotting factor (Spf) from the Spotted-dilute System in Maize Is a Member of the En/Spm Controlling Element Family

Article Abstract:

Research shows that maize receptors responded equally to En/Spm and Spf, identifying Spf is a member of controlling element family En/Spm.
