Early Withering of Enlarged Ovules in Pollinated Fruits of Bananas (Musa spp.) Suggest Abortion after Fertilization

Horticulturae, 2022
Sterility in edible bananas is as a result of a long history of anthropogenic-driven selection for sterile genotypes, since seed is not desirable in fruit pulp for human consumption.

Standardizing ovule age for in ovulo embryo rescue in seedless grape (Vitis vinifera) breeding under the subtropical region

The Indian Journal of Agricultural Sciences
The present study was carried out during 2018–22 at ICAR-Indian Agricultural Research Institute, New Delhi to identify the appropriate ovule age (days after pollination-DAP) to rescue the in ovulo embryo after pollination in various seedless grape ...

Ovule Gene Expression Analysis in Sexual and Aposporous Apomictic Hypericum perforatum L. (Hypericaceae) Accessions

Frontiers in Plant Science, 2019
Hypericum perforatum L. (2n = 4x = 32) is an attractive model system for the study of aposporous apomixis. The earliest phenotypic features of aposporous apomixis in this species are the mitotic formation of unreduced embryo sacs from a somatic cell of ...

OVULATION AND MENSTRUATION [PDF]

BMJ, 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.

Genomic identification of cotton SAC genes branded ovule and stress-related key genes in Gossypium hirsutum

Frontiers in Plant Science, 2023
SAC genes have been identified to play a variety of biological functions and responses to various stresses. Previously, SAC genes have been recognized in animals and Arabidopsis.

TOGR3, a Proteasome β4 Subunit, Orchestrates Sugar Homeostasis to Trade Off Growth and Thermotolerance in Rice

Advanced Science, EarlyView.
This study identifies a novel thermoregulatory mechanism in rice: TOGR3 partners with 26S proteasome subunits, including TT1, to drive thermoresponsive ubiquitin–proteasome activity, maintaining sugar homeostasis in stomatal regulation to balance growth and stress resistance.

Genetic Diagnosis and Discovery Enabled by Large Language Models

Advanced Science, EarlyView.
We demonstrate that large language models (LLMs) can facilitate genetic diagnosis and discovery. LLMs were used to solve four types of genetic problems of sequentially increased complexity. An LLM‐based pipeline could analyze genetic variants in the genomic sequences of human hearing loss or rare genetic disease patients and assist in identifying ...

Structural aspects of the zygotic embryogenesis of Acca sellowiana (O. Berg) Burret (Myrtaceae) Aspectos estruturais da embriogênese zigótica em Acca sellowiana (O. Berg) Burret (Myrtaceae)

Acta Botânica Brasílica, 2009
Acca sellowiana has anatropous, bitegmic and crassinucellate ovules. The outer and inner integuments are double-layered except in the micropyle, where they are composed of more layers; the micropyle is zig-zag shaped.
