Engineering meiotic recombination pathways in rice

Plant Biotechnology Journal, Volume 17, Issue 11, Page 2062-2077, November 2019., 2019
Summary In the last 15 years, outstanding progress has been made in understanding the function of meiotic genes in the model dicot and monocot plants Arabidopsis and rice (Oryza sativa L.), respectively. This knowledge allowed to modulate meiotic recombination in Arabidopsis and, more recently, in rice. For instance, the overall frequency of crossovers

Embryo sac development in some South African cultivars of Lantana camara

Bothalia: African Biodiversity & Conservation, 1982
Twenty embryo sacs from each of 20 different  Lantana camara L. cultivars naturalized in South Africa were examined. The normal sexual embryo sacs were monosporic 8-nucleated embryo sacs of the polygonum type and were encountered in 55% of the material ...

Retro-Element Gypsy-163 Is Differentially Methylated in Reproductive Tissues of Apomictic and Sexual Plants of Cenchrus ciliaris

Frontiers in Genetics, 2020
Apomixis, an asexual mode of reproduction through seeds, has immense scope for crop improvement due to its ability to fix hybrid vigor. In C. ciliaris, a predominantly apomictically reproducing range grass, apomixis is genetically controlled by an ...

Heterosis and Expressivity of Apospory in Tetraploid Bahiagrass Hybrids

Crop Science, 2015
ABSTRACTBreeding procedures developed for apomictic species are based on the idea of fixing superior hybrids by apomixis. However, scarce information is available about the occurrence of heterosis in apomictic hybrids. The objective was to generate a group of apomixis‐segregating tetraploid bahiagrass (Paspalum notatum Flüggé) families, evaluate the ...

Bangiales (Rhodophyta) in New Zealand: current state of knowledge and future directions

New Zealand Journal of Botany, Volume 63, Issue 5, Page 2245-2263, December 2025.
ABSTRACT Members of the red algal order Bangiales are morphologically simple, with the gametophyte generation consisting of either filaments or blades, and the sporophyte generation consisting of microscopic uniseriate branched filaments. An ancient lineage, the order is distributed worldwide.

Building a botanical foundation for perennial agriculture: Global inventory of wild, perennial herbaceous Fabaceae species

PLANTS, PEOPLE, PLANET, Volume 1, Issue 4, Page 375-386, October 2019., 2019
Wild, perennial, herbaceous plant species have the capacity to provide both agricultural products and ecological services, such as soil stability and efficient absorption, over multiple years. Although perennial, herbaceous species are common in nature, these species were rarely domesticated.

Reproductive strategy in the Ranunculus auricomus complex (ranunculaceae)

Acta Societatis Botanicorum Poloniae, 2014
A preliminary study of reproductive strategy was carried out on plants representing four cytotypes of the Ranunculus auricomus complex. Diploid plants reproduce sexually, triploids, tetraploids and hexaploids have an apomictic mode of reproduction ...

The relation of meiotic behaviour to hybridity, polyploidy and apomixis in the Ranunculus auricomus complex (Ranunculaceae)

BMC Plant Biology, 2020
Background Hybridization and polyploidization are powerful evolutionary factors that are associated with manifold developmental changes in plants such as irregular progression of meiosis and sporogenesis.

Maternal haploid induction in maize via mutation of Gamete Expression protein 1

Plant Biotechnology Journal, Volume 23, Issue 7, Page 2595-2607, July 2025.
Summary Doubled haploid (DH) technology, based on haploid induction (HI), is a crucial tool in enhancing crop‐breeding efficiency and has been successfully applied in various plant species. While many HI‐related genes have been identified using diverse strategies, the genetic basis and molecular mechanisms underlying HI remain incompletely understood ...

Role of paternal Oryza sativa Baby Booms (OsBBMs) in initiating de novo gene expression and regulating early zygotic development in rice

The Plant Journal, Volume 122, Issue 6, June 2025.
SUMMARY Oryza sativa BABY BOOM 1 (OsBBM1), a member of the AP2/ERF family of transcription factors, is expressed from paternal allele in rice zygote and plays a crucial role in initiating zygotic development. However, the mechanism how the paternal OsBBM1 drives this development remains unclear. Rice zygotes with four different gamete combinations with
