Description

Seedlings receive 3hrs of white light to germinate, then are entrained under 12/12 FR/D cycles for 3 days, sprayed, and imaged 24hrs after under 1 FR/D cycle, 3 days of continuous FR and 48h of DD

Purpose

Analysis of CCA1 and CCR2 in phyb, elf3-4, elf4-1 and toc1-4 mutants under strict FR light treatment

Comments

Extremely bad contamination (fungus and bacteria)

Sample preparation

Plates were sprayed with luciferin 24 hrs before measurement

Measurement

Protocol

Luciferase luminescence (HAM 3)

A picture every 1.5 hr

Experimental conditions

FR growth conditions

Growth on Agar 1.2% MS 0.5;Agar 1.5% MS 1 3% Sucrose for 4.0 days (FR growth conditions).
