Figure 6. LesaDOG1 transcript expression pattern determined by qRT-PCR in specific Lepidium sativum FR1 seed tissues during incubation on medium without (CON) or with ABA added. Relative expression values based on the comparison with validated constitutive transcripts are presented.
(A) Micropylar seed ends (radicle plus endosperm cap) of dry (0h) and imbibed (8h ± ABA) seeds are compared; 8h-CON was set to 1. Note that tissue separation of dry seeds is not possible.
(B) Radicles and micropylar endosperm caps dissected from seeds at the times indicated were analysed; radicle 8h-CON was set to 1. Numbers above the columns are the percentage of endosperm rupture of the seed populations. Mean values +SE of 4 biological replicas; incubation of seeds at 24 ºC in continuous light, ± 10 µM ABA.
