Sep 24, 2021 · The single ovule integument of Ginkgo biloba acquires the typical characteristics of the seed coat long before the fertilization event. In this study, we investigated whether pollination triggers the transformation of the ovule integument into the seed coat.

Nov 17, 2024 · Once you’ve gathered fallen ginkgo fruit, remove the pulpy orange exterior to get to the inner seed. This is called the ovule. Rinse the pulp off under water and pick out the oval ovule nut. Discard any ovules that are shriveled or damaged. Place cleaned ovules in a plastic bag with a bit of moist peat moss.

Nov 9, 2021 · Through in-depth comparative transcriptome analyses of Ginkgo biloba developing ovules, pollen cones, and megagametophytes we have been able to identify novel genes, likely involved in ovule...

Nov 6, 2024 · These ovules grow into the distinctive Ginkgo seeds. The female strobili, or cones, grow from the leaf axils on dwarf shoots. Each strobilus has a long peduncle that splits at the top.

The single ovule integument of Ginkgo biloba acquires the typical characteristics of the seed coat long before the fertilization event. In this study, we investigated whether pollination triggers the transformation of the ovule integument into the seed coat.

Each consists of a stalk that bears two or sometimes three or more erect ovules. An ovule is composed of an integument (the future seed coat) surrounding a tissue called the nucellus. It is in the nucellus that meiosis occurs, resulting in the formation of four haploid megaspore cells.

Ovule development in Ginkgo biloba is examined. Ovulate stalks are initiated in leaf axils, and each stalk primordium dichotomizes to produce two ovule primordia. Integument development appears circumferential and during micropyle formation becomes slightly lobed.

Sep 1, 2021 · In this study, we investigated whether pollination triggers the transformation of the ovule integument into the seed coat. Transcriptomics and metabolomics analyses performed on ovules just...

The single ovule integument of Ginkgo biloba acquires the typical characteristics of the seed coat long before the fertilization event. In this study, we investigated whether pollination triggers the transformation of the ovule integument into the seed coat.

Mar 9, 2024 · To investigate the genetic and molecular networks controlling ovule response to pollination in Ginkgo, we performed a transcriptomic analysis on ovules collected from both plants that received pollen and unpollinated plants.
