Egg production in a coastal seabird, the glaucous-winged gull (Larus glaucescens), declines during the last century. [PDF]

open access: yesPLoS ONE, 2011
Seabirds integrate information about oceanic ecosystems across time and space, and are considered sensitive indicators of marine conditions. To assess whether hypothesized long-term foodweb changes such as forage fish declines may be reflected in a ...

Genome‐wide association mapping identifies novel loci underlying fire blight resistance in apple

open access: yesThe Plant Genome, 2021
Fire blight, caused by epiphytotic gram‐negative bacteria Erwinia amylovora, is the most destructive bacterial disease of apple (Malus spp.). Genetic mechanisms of fire blight resistance have mainly been studied using traditional biparental quantitative ...

Status and way-forward in breeding potato (Solanum tuberosum) for resistance to late blight

open access: yesThe Indian Journal of Agricultural Sciences, 2023
Improving host resistance to late blight (Phytophthora infestans) has been a major concern of potato breeders since the Irish famine of 1840s. Since then, a number of late blight resistant potato (Solanum tuberosum L.) cultivars have been developed ...

Discrimination and Detection of and with a Single Primer Set [PDF]

open access: yesThe Plant Pathology Journal, 2022
Erwinia amylovora and Erwinia pyrifoliae cause fire blight and black-shoot blight, respectively, in apples and pears. E. pyrifoliae is less pathogenic and has a narrower host range than that of E. amylovora.

Genome-Wide Association Mapping of Late Blight Tolerance Trait in Potato (Solanum tuberosum L.)

open access: yesFrontiers in Genetics, 2021
Uncovering the genetic basis and optimizing the late blight tolerance trait in potatoes (Solanum tuberosum L.) are crucial for potato breeding. Late blight disease is one of the most significant diseases hindering potato production.
