Fig. 1: Characterization of F. vesca mutants of FveAGL62 and FveAGL80.
From: Mechanism of fertilization-induced auxin synthesis in the endosperm for seed and fruit development
a ProFveAGL62::FveAGL62-GUS reporter expression in stage 1 ovule (pre-fertilization) and stage 2 seed (post-fertilization). b ProFveAGL80::FveAGL80-GUS reporter expression in stage 1 ovule and stage 2 seed. c Diagram of a stage 2 strawberry seed. d Mature F. vesca plants of WT, fveagl62 single, fveagl80 single, and fveagl62 fveagl80 double mutant. fveagl62 single and fveagl62 fveagl80 double mutants fail to produce fruits. e Comparison of receptacle fruit development at the three earliest stages of fruit development. f WT and fveagl62 stage 1 ovules and stage 2 seeds. g Fruits from self-cross or reciprocal crosses between WT and fveagl62 (female genotype is listed first). Only self-cross of fveagl62 leads to failed fruit growth. h GUS expression in stage 2 seeds derived from reciprocal crosses between ProFveAGL62::FveAGL62-GUS transgenic plants and WT. i fveagl62 mutant fruits and seeds after different hormone treatments. Scale bars: 0.12 mm (a, b, h), 5 cm (d), 0.5 cm (e), 1 mm (f), 1 cm (g), 0.5 cm (fruit) (i) and 1 mm (seed) (i).
