Development of Efficient Plant Regeneration and Transformation System for Impatiens Using Agrobacterium tumefaciens and Multiple Bud Cultures as Explants

open access: yesBMC Plant Biology, 2010
Background Impatiens (Impatiens walleriana) is a top selling floriculture crop. The potential for genetic transformation of Impatiens to introduce novel flower colors or virus resistance has been limited by its general recalcitrance to tissue culture and

Fire frequency and timing influence bee–flower interactions: a case study from an oak‐pine savanna restoration on the Cumberland Plateau

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Native plant communities have declined in the southeastern United States over the past century because of habitat loss and fire suppression. While restoration of these communities often requires prescribed fire, the effects of fire on endemic insects remain unclear.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 4, Page 636-647, November 2026.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...
