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

open access: yesThe 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

Prospects and limits of the flow cytometric seed screen – insights from Potentilla sensu lato (Potentilleae, Rosaceae)

open access: yesNew Phytologist, Volume 198, Issue 2, Page 605-616, April 2013., 2013
Summary The flow cytometric seed screen allows for identification of reproductive modes of seed formation and inference of the ploidy of contributing gametes. However, the lack of a mathematical formalization to infer male/female genomic contributions, and the prerequisite of a binucleate female contribution to the endosperm limits its applicability ...

Genetic Dissection of Apomixis in Dandelions Identifies a Dominant Parthenogenesis Locus and Highlights the Complexity of Autonomous Endosperm Formation

open access: yesGenes, 2020
Apomixis in the common dandelion (Taraxacum officinale) consists of three developmental components: diplospory (apomeiosis), parthenogenesis, and autonomous endosperm development.

Taxonomic identification and life cycle comparison of two populations of the monostromatic green algae Monostroma nitidum

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
This study employed molecular markers and morphological studies of two populations of Monostroma nitidum collected from YJ and ZJ. The results revealed no obvious differences in tufA and 18S rDNA sequences between the two populations, although there were extremely significant differences in morphological characteristics. M.

Distinct geographic parthenogenesis in spite of niche conservatism and a single ploidy level: A case of Rubus ser. Glandulosi (Rosaceae)

open access: yesNew Phytologist, Volume 242, Issue 3, Page 1348-1362, May 2024.
Summary Asexual organisms often differ in their geographic distributions from their sexual relatives. This phenomenon, termed geographic parthenogenesis, has long been known, but the underlying factors behind its diverse patterns have been under dispute. Particularly problematic is an association between asexuality and polyploidy in most taxa. Here, we

Table_2_Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals.DOCX

open access: yes, 2019
Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo ...

Data_Sheet_2_Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera.FASTA

open access: yes, 2022
Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Boechera cinsinde apomiksi ile ilişkili genlerin ortaya çıkarılması: BM, APOLLO, ve LEC2 [PDF]

open access: yes, 2023
Apomiksi, bitkilerde partenonegenez (cinsel üremenin döllenme aşamalarından kaçınma) ve apomayoz (mayozda anormalilerin görülmesi ya da mayozun engellenmesi) sonucunda dişi ebeveyne özdeş embriyolar üreten bir eşeysiz üreme yöntemidir.
