Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]
, 2017 Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

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

Mutation Accumulation in an Asexual Relative of Arabidopsis. [PDF]
PLoS Genetics, 2017 Asexual populations experience weaker responses to natural selection, which causes deleterious mutations to accumulate over time. Additionally, stochastic loss of individuals free of deleterious mutations can lead to an irreversible increase in ...

Somatic embryogenesis in apomictBoechera holboellii
Acta 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:

On the origin and evolution of apomixis in Boechera [PDF]
Plant Reproduction, 2013 The genetic mechanisms causing seed development by gametophytic apomixis in plants are predominantly unknown. As apomixis is consistently associated with hybridity and polyploidy, these confounding factors may either (a) be the underlying mechanism for the expression of apomixis, or (b) obscure the genetic factors which cause apomixis.

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

Different transcript patterns in response to specialist and generalist herbivores in the wild Arabidopsis relative Boechera divaricarpa. [PDF]
PLoS ONE, 2007 BACKGROUND: Plants defend themselves against herbivorous insects, utilizing both constitutive and inducible defenses. Induced defenses are controlled by several phytohormone-mediated signaling pathways.

Pathways to polyploidy : indications of a female triploid bridge in the alpine species Ranunculus kuepferi (Ranunculaceae) [PDF]
, 2017 Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring (triploid bridge), or with other ...

Using Brassica Cover Crops as Living Mulch in a Vineyard, Changes over One Growing Season
International Journal of Plant Biology, 2023 Farmers hoping to manage cropping systems sustainably are turning to cover crops to help mitigate plant pathogens. Plants with biofumigant properties are used to control soil-borne pathogens in agricultural settings, especially in till systems, where the
