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 the main clock markers in elf4, elf3, gi and phya mutants under strict FR light treatment

Comments

Sample preparation

Plates were sprayed with luciferin 24 hrs before measurement

Measurement

Protocol

Luciferase luminescence (HAM 3)

A picture every 1.5 hr
