Fig. 11From: Transcriptomic profiling identifies differentially expressed genes associated with programmed cell death of nucellar cells in Ginkgo biloba L.Ovule collection from G. biloba strobili at the stage of pre-PCF (a) or post-PCF (b). Magnified view of the boxed area shows ovules (arrowheads) collected from megasporophyll, and red-dash lines marking the junction region between ovules and megasporophyll. G. biloba leaves (asterisks) are positioned along with ovules. Bars = 1 cmBack to article page
