Gene Expression Profiles in Rice Developing Ovules Provided Evidence for the Role of Sporophytic Tissue in Female Gametophyte Development.

open access: yesPLoS ONE, 2015
The development of ovule in rice (Oryza sativa) is vital during its life cycle. To gain more understanding of the molecular events associated with the ovule development, we used RNA sequencing approach to perform transcriptome-profiling analysis of the ...

Dynamic Roles for Small RNAs and DNA Methylation during Ovule and Fiber Development in Allotetraploid Cotton.

open access: yesPLoS Genetics, 2015
DNA methylation is essential for plant and animal development. In plants, methylation occurs at CG, CHG, and CHH (H = A, C or T) sites via distinct pathways. Cotton is an allotetraploid consisting of two progenitor genomes. Each cotton fiber is a rapidly-

Anatomical Study on the Multi-Ovule Development and Abortion of Hanfu Apple

open access: yesJournal of Integrative Agriculture, 2014
The terminal flower buds of 6-yr-old Hanfu apple were used to study the ovule development, ovular characteristics, cell death of abortive ovules, and dynamic change of starch grain quantity in the embryo sac with paraffin slices and terminal ...

Formation of the female generative structures in Deutzia scarba (Hydrangeaceae)

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2005
The development and the structure of the ovule and the embryo sac of the representative of the family Hydrangeaceae Deutzia scarba are investigated. It is established that the ovule of the given species is hemitropic, tenuinucellatic, unitegmic.

Deciphering the Molecular Mechanisms That Control Ovule Development in Pomegranate

open access: yesHorticulturae
Plant seed number depends on ovule number initiated within the carpels, and it serves as a primary factor shaping fruit yield. Pomegranate trees exhibit bisexual flowers and functional male flowers.

Angiosperm ovules: diversity, development, evolution [PDF]

open access: yesAnnals of Botany, 2011
In angiosperms the presence of an outer integument appears to be instrumental for ovule curvature, as indicated from studies on ovule diversity through the major clades of angiosperms, molecular developmental genetics in model species, abnormal ovules in a broad range of angiosperms, and comparison with gymnosperms with curved ovules.

An optimised clearing protocol for the quantitative assessment of sub-epidermal ovule tissues within whole cereal pistils

open access: yesPlant Methods, 2017
Background Seed development in the angiosperms requires the production of a female gametophyte (embryo sac) within the ovule. Many aspects of female reproductive development in cereal crops are yet to be described, largely due to the technical difficulty

Development of the Ovulate Strobilus and Young Ovule of Zamia Floridana [PDF]

open access: yesBotanical Gazette, 1910
1. The young staminate and ovulate strobili can be distinguished by the difference in breadth, number of sporophylls, and number of meristematic points. 2. There is probably a single archesporial cell giving rise to a group of cells, one of which becomes the megaspore mother cell. 3.
