Response of the MFT knock-out mutant and wild-type (WT), which is Columbia (Col-0) to current (380 ppm) and elevated (700 ppm) CO₂.

<p>Symbols are means ± 1 standard error.</p

Frequency distribution of RIL responses for flowering time.

<p>The x-axis was calculated as days to flower at 700 ppm [CO₂] minus days to flower 380 ppm [CO₂]. Thus, positive values represent delays in flowering at elevated [CO₂] and negative values represent more rapid flowering (with 0 being no change in flowering time due to [CO₂]). Differences for parental Cvi-0 and SG are shown with arrows.</p

Linkage map showing the distribution of SNP markers across the five chromosomes used in our QTL study.

<p>The markers associated with particular flowering time genes are identified in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049028#pone.0049028.s003" target="_blank">Table S1</a>.</p
