Light Quality Regulates PKS1 Protein Accumulation.

(A) Immunoblot analysis of 5-day-old dark-grown wild-type seedlings transferred for 1, 2, 4, or 18 h to continuous R.

(B) Immunoblot analysis of 5 day-old dark-grown wild-type seedlings transferred for 1, 2, 4, or 18 h to continuous FR.

(C) Immunoblot analysis of 3-day-old dark-grown wild-type seedlings treated with 1, 2, 4, or 18 hourly pulses of FR light and a pks1 mutant treated with 2 FR pulses as a control.

All protein gel blots were probed with anti-PKS1 antibodies and anti-DET3 antibodies as a loading control. Col, Columbia wild type; D, darkness.
