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 ...

Distinctive patterns of callose deposition provide an early sign of ovule abortion in the andromonoecious shrubCaesalpinia gilliesi

open access: yesBoletín de la Sociedad Argentina de Botánica, 2009
Ovule abortion may lead to the partial or complete reduction of the number of functional ovules in the ovary and then is the primary factor that determines the sexual expression of the plant.

OVULATION AND MENSTRUATION [PDF]

open access: yesBMJ, 1934
To the Editor:— I should like to be given the opportunity of replying to Dr. Novak's letter inThe Journaldated April 21. I agree with Hartman that the disintegration changes in the endometrium during the anovular cyclic hemorrhage of the macaque and during menstruation in the human female are almost identical.

Characterizations of a Class-I BASIC PENTACYSTEINE Gene Reveal Conserved Roles in the Transcriptional Repression of Genes Involved in Seed Development

open access: yesCurrent Issues in Molecular Biology, 2022
The developmental regulation of flower organs involves the spatio-temporal regulation of floral homeotic genes. BASIC PENTACYSTEINE genes are plant-specific transcription factors that is involved in many aspects of plant development through gene ...

Intrahepatic ovulation [PDF]

open access: yesRadiology Case Reports, 2014
Ectopic ovaries are a rare finding in the literature, with fewer than 50 published cases to date. This phenomenon has been found in the omentum, bladder, mesentery, and uterus; attached to the colon; inside the left labia majora; and in the kidney.

Development of Embryo Suspensors for Five Genera of Crassulaceae with Special Emphasis on Plasmodesmata Distribution and Ultrastructure

open access: yesPlants, 2020
The suspensor in the majority of angiosperms is an evolutionally conserved embryonic structure functioning as a conduit that connects ovule tissues with the embryo proper for nutrients and growth factors flux.

Molecular control of ovule development

open access: yes, 1996
Enormous progress has been made over the past five years in understanding the floral homeotic genes, which specify the fate of the floral organ meristems. More recently, regulatory genes have been cloned from Petunia hybrida and Arabidopsis thaliana that
