Effects of mutations and transgenes on flowering time. Flowering time is presented as the number of leaves (rosette, cauline, and total) formed on the main shoot; plants that flower later form more leaves. At least five plants of each genotype were examined, except 35S::SOC1 #3, which did not form seeds. The flowering time oflfy-6 is measured using rosette leaves only, because this mutation causes the growth of extra cauline leaves. AGL20 T2 plants were selected with the herbicide Challenge (active ingredient glufosinate ammonium) before scoring to identify those that contained the transgene.
