Apomeiotic pollen mother cell development in the apomictic Boechera species

open access: yesBiologia plantarum, 2009
Pollen mother cell (PMC) development in the apomictic Boechera species B. holboellii, B. gunnisoniana and B. divaricarpa were investigated by various cytological methods. In prophase I, in triploid species B. holboellii and B. gunnisoniana the individual chromosomes condensed into long strands within the nucleus. Then, in metaphase I, each PMC formed a

Functional Signatures of the Epiphytic Prokaryotic Microbiome of Agaves and Cacti. [PDF]

open access: yes, 2019
Microbial symbionts account for survival, development, fitness and evolution of eukaryotic hosts. These microorganisms together with their host form a biological unit known as holobiont. Recent studies have revealed that the holobiont of agaves and cacti

Mining the Plant-Herbivore Interface with a Leafmining Drosophila of Arabidopsis [PDF]

open access: yes, 2014
Experimental infections of Arabidopsis thaliana (Arabidopsis) with genomically characterized plant pathogens such as Pseudomonas syringae have facilitated the dissection of canonical eukaryotic defence pathways and parasite virulence factors.

Bioclimatic transect networks: powerful observatories of ecological change [PDF]

open access: yes, 2017
First published: 19 May 2017Transects that traverse substantial climate gradients are important tools for climate change research and allow questions on the extent to which phenotypic variation associates with climate, the link between climate and ...

Genome-wide identification and expression analysis of SWI1 genes in Boechera species

open access: yesComputational Biology and Chemistry, 2016
As a mode of reproduction in plants, apomixis leads to the generation of clones via seeds. Apomictic plants form viable diploid female gametes without meiosis (apomeiosis) and produce embryos without fertilization (parthenogenesis). Apomeiosis, as a major component of apomixis, has recently been reported in some Arabidopsis thaliana mutants; dyad ...

Transfer of Most North American Species of Arabis to Boechera (Brassicaceae)

open access: yesNovon, 2003
Based on extensive molecular, cytological, and morphological studies, most of the North American species of Arebas (Brassicaceae) are recognized herein as members of the genus Boechera. Morphological differences between the two genera are discussed, and species formerly placed in Arabis and not included here in Boechera are assigned to other genera ...

From a Phenotype to Transcriptomics Apomixis Initiation in the genus Boechera [PDF]

open access: yes, 2009
The North American genus Boechera provides a highly polymorphic source of natural variation for studies on the regulation of apomictic development (asexual reproduction via seed). The aim of the research conducted was to qualify and quantify naturally-occurring reproductive variation in apomictic and sexual accessions (genotypes), and to further ...
