Largest genome assembly in Brassicaceae: retrotransposon-driven genome expansion and karyotype evolution in Matthiola incana. [PDF]
Plant Biotechnol JSummary Matthiola incana, commonly known as stock and gillyflower, is a widely grown ornamental plant whose genome is significantly larger than that of other species in the mustard family. However, the evolutionary history behind such a large genome (~2 Gb) is still unknown.

Globally Relaxed Selection and Local Adaptation in Boechera stricta. [PDF]
Genome Biol Evol, 2022 AbstractThe strength of selection varies among populations and across the genome, but the determinants of efficacy of selection remain unclear. In this study, we used whole-genome sequencing data from 467 Boechera stricta accessions to quantify the strength of selection and characterize the pattern of local adaptation. We found low genetic diversity on

Boechera species exhibit species-specific responses to combined heat and high light stress. [PDF]
PLoS ONE, 2015 As sessile organisms, plants must be able to complete their life cycle in place and therefore tolerance to abiotic stress has had a major role in shaping biogeographical patterns. However, much of what we know about plant tolerance to abiotic stresses is

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

Evolution of Repetitive Genomic Content and Gene Families Over Geo-Climatic Gradients in Brassicaceae. [PDF]
Ecol EvolAlong temperature gradients such as elevation and latitude, species typically occupy distinct ranges, and life at the extremes may come with adaptive and non‐adaptive genomic changes. In the Brassicaceae family, comparative genomics revealed that geo‐climatic factors strongly predict genome size and transposable element (TE) content, explaining up to ...

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]
American 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 ...

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

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti-herbivore defenses, selection for qualitative toxins, and acceleration of plant-herbivore coevolution. [PDF]
Am J BotAbstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.
