Gynodioecy is a sexual system wherein females coexist with hermaphrodites. It is of interest
not only because male-sterile plants are advantageous in plant breeding but also because it can be a crucial
step in the evolutionary transition to entirely separate sexes (dioecy) from a hermaphroditic ancestor. The
gynodioecious diploid wild...
The filamentous fungus Neurospora crassa responds to light in complex ways. To thoroughly study the transcriptional response of this organism to light, RNA-seq was used to analyze capped and polyadenylated mRNA prepared from mycelium grown for 24 hr in the dark and then exposed to light for 0 (control) 15,...
Many nonmodel species exemplify important biological questions but lack the sequence resources required to study the genes and genomic regions underlying traits of interest. Reef-building corals are famously sensitive to rising seawater temperatures, motivating ongoing research into their stress responses and long-term prospects in a changing climate. A comprehensive understanding...
Genome defense likely evolved to curtail the spread of transposable elements and invading viruses. A combination of effective defense mechanisms has been shown to limit colonization of the Neurospora crassa genome by transposable elements. A novel DNA transposon named Sly1-1 was discovered in the genome of the most widely used...
Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses. To enable basic and applied research of this important pest, we sequenced the D. suzukii genome...
Gynodioecy, the coexistence of females and hermaphrodites, occurs in 20% of angiosperm families and often enables transitions between hermaphroditism and dioecy. Clarifying mechanisms of sex determination in gynodioecious species can thus illuminate sexual system evolution. Genetic determination of gynodioecy, however, can be complex and is not fully characterized in any...
Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across...

A method for Agrobacterium-mediated transformation of hybrid
poplar (Populus alba x P. grandidentata) suspension cultures and
regeneration of transformed plants is described. The best protocol
was one in which suspension cultures were inoculated with
Agrobacterium tumefaciens to a density of 10⁷ cfu's/ml, cocultivated
for 48 hours, plated to cellulose acetate...
Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...
