A continental-wide perspective: the genepool of nuclear encoded ribosomal DNA and single-copy gene sequences in North American Boechera (Brassicaceae). [PDF]

open access: yesPLoS ONE, 2012
74 of the currently accepted 111 taxa of the North American genus Boechera (Brassicaceae) were subject to pyhlogenetic reconstruction and network analysis. The dataset comprised 911 accessions for which ITS sequences were analyzed.

Polyembryonic or Apomictic Seeds Enable Fig Trees to Establish New Populations Without Their Pollinating Wasps, a Case Observation in <i>Ficus gasparriniana</i>. [PDF]

open access: yesEcol Evol
Development of apomictic adventitious embry o in Ficus gasparriniana. Apomixis is a key reproductive strategy for F. gasparriniana, especially when pollination by fig wasps is limited. In the absence of pollination, F. gasparriniana produces seeds through adventitious embryos formed within the nucellar tissue, which is accompanied by polyploidization ...

The genome sequence of Barbarea vulgaris facilitates the study of ecological biochemistry [PDF]

open access: yes, 2017
peer-reviewedThe genus Barbarea has emerged as a model for evolution and ecology of plant defense compounds, due to its unusual glucosinolate profile and production of saponins, unique to the Brassicaceae. One species, B.

Evolutionary processes from the perspective of flowering time diversity. [PDF]

open access: yes, 2020
Although it is well appreciated that genetic studies of flowering time regulation have led to fundamental advances in the fields of molecular and developmental biology, the ways in which genetic studies of flowering time diversity have enriched the field

Somatic embryogenesis in apomictBoechera holboellii

open access: yesActa Biologica Hungarica, 2009
In this study we establish an efficient method for the regeneration for Boechera holboellii via somatic embryogenesis. Immature cotyledons from siliques of 4-6 month-old plants were cultured on MS medium supplemented with plant growth regulators (BA - 6-benzylaminopurine; NAA - alpha-naphthaleneacetic acid; TDZ - 1-phelyl-3-(1,2,3-thiadiazol-5-yl) urea:

Charecterization of thePHERES1Orthologs in the ApomictBoechera [PDF]

open access: yesBiotechnology & Biotechnological Equipment, 2009
ABSTRACTHere we report the structure and expression patterns of orthologs for PHERES1 (PHE1) gene in the apomict Boechera holboellii. The PHE1 cDNAs were obtained by RT-PCR from Boechera anthers and carpels before and after fertilization. PHE1 encodes a type 1 MADS box protein and promotes seed growth. Also, PHE1 shows monoallelic expression and is the

Major transcriptome reprogramming underlies floral mimicry induced by the rust fungus Puccinia monoica in Boechera stricta. [PDF]

open access: yesPLoS ONE, 2013
Pucciniamonoica is a spectacular plant parasitic rust fungus that triggers the formation of flower-like structures (pseudoflowers) in its Brassicaceae host plant Boecherastricta.

Island species radiation and karyotypic stasis in Pachycladon allopolyploids [PDF]

open access: yes, 2010
Background Pachycladon (Brassicaceae, tribe Camelineae) is a monophyletic genus of ten morphologically and ecogeographically differentiated, and presumably allopolyploid species occurring in the South Island of New Zealand and ...

Apomixis and Gene Expression in Boechera [PDF]

open access: yesThe Plant Cell, 2010
The ability to induce apomixis, the production of seeds from maternal tissues without fertilization or meiosis, in crop plants has been referred to as a holy grail of plant biology. Apomixis leads to genetically identical progeny, which would, for instance, allow crops to retain complex ...

Quantitative variation for apomictic reproduction in the genus Boechera (Brassicaceae) [PDF]

open access: yesAmerican Journal of Botany, 2010
• Premise of the study: The evolution of asexual seed production (apomixis) from sexual relatives is a great enigma of plant biology. The genus Boechera is ideal for studying apomixis because of its close relation to Arabidopsis and the occurrence of sexual and apomictic species at low ploidy levels (diploid and triploid).
