Intraspecific diversification in North American Boechera stricta (= Arabis drummondii), Boechera ×divaricarpa, and Boechera holboellii (Brassicaceae) inferred from nuclear and chloroplast molecular markers—an integrative approach [PDF]

open access: yesAmerican Journal of Botany, 2004
We performed a combined evolutionary analysis of North American Boechera stricta, Boechera holboellii, and their hybrid Boechera ×divaricarpa using information on ploidy level estimators, allelic microsatellite variation, noncoding regions of the plastidic genome (cpDNA), and sequences of the internal transcribed spacers 1 and 2 of the nuclear ...

Variation and fitness costs for tolerance to different types of herbivore damage in Boechera stricta genotypes with contrasting glucosinolate structures. [PDF]

open access: yesNew Phytol, 2010
• Analyses of plant tolerance in response to different modes of herbivory are essential to an understanding of plant defense evolution, yet are still scarce. Allocation costs and trade-offs between tolerance and plant chemical defenses may influence genetic variation for tolerance.

Complex trait divergence contributes to environmental niche differentiation in ecological speciation of Boechera stricta. [PDF]

open access: yesMol Ecol, 2013
AbstractEcological factors may contribute to reproductive isolation if differential local adaptation causes immigrant or hybrid fitness reduction. Because local adaptation results from the interaction between natural selection and adaptive traits, it is crucial to investigate both to understand ecological speciation. Previously, we used niche modelling

Activation and suppression mechanisms of the NRG1 helper NLRs. [PDF]

open access: yesJ Integr Plant Biol
This commentary examines two recent papers featuring intriguing discoveries on the molecular processes and structural foundations involved in the activation and suppression of the N‐requirement gene 1 (NRG1) helper nucleotide‐binding leucine‐rich repeat receptor.

Variation in circadian rhythms is maintained among and within populations in Boechera stricta [PDF]

open access: yesPlant, Cell & Environment, 2016
AbstractCircadian clocks have evolved independently in all three domains of life, and fitness benefits of a functional clock have been demonstrated in experimental genotypes in controlled conditions. Still, little is known about genetic variation in the clock and its fitness consequences in natural populations from heterogeneous environments.

Identification of quantitative trait loci and a candidate locus for freezing tolerance in controlled and outdoor environments in the overwintering crucifer Boechera stricta. [PDF]

open access: yesPlant Cell Environ, 2014
AbstractDevelopment of chilling and freezing tolerance is complex and can be affected by photoperiod, temperature and photosynthetic performance; however, there has been limited research on the interaction of these three factors. We evaluated 108 recombinant inbred lines of Boechera stricta, derived from a cross between lines originating from Montana ...

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

Partial Shotgun Sequencing of the Boechera stricta Genome Reveals Extensive Microsynteny and Promoter Conservation with Arabidopsis [PDF]

open access: yesPlant Physiology, 2006
Abstract Comparative genomics provides insight into the evolutionary dynamics that shape discrete sequences as well as whole genomes. To advance comparative genomics within the Brassicaceae, we have end sequenced 23,136 medium-sized insert clones from Boechera stricta, a wild relative of Arabidopsis (Arabidopsis thaliana).

Microbiome-Mediated Resistance of Wild Tomato to the Invasive Insect Prodiplosis longifila. [PDF]

open access: yesEnviron Microbiol Rep
Soil microbiome‐mediated resistance to Prodiplosis longifila in wild tomato. Wild tomato Solanum pimpinellifolium exhibited reduced leaf damage from P. longifila when gronw in live soil compared to sterilized soil. Sterilization disrupted root‐associated microbiome, particularly reduced the abundance of Actinoplanes, which is linked to biosynthetic ...
