Predicting maize phenology: intercomparison of functions for developmental response to temperature
(American Society of Agronomy, 2014-12)Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision ... -
Evaluation of different live Salmonella enteritidis vaccine schedules administered during layer hen rearing to reduce excretion, organ colonization, and egg contamination
(Oxford University Press, 2019-01-25)Salmonellosis caused by Salmonella Enteritidis is a widespread zoonosis and poultry products are an important source of infection. This study was carried out to evaluate the protection of different vaccination schedules ... -
Gene content and distribution in the nuclear genome of Fragaria vesca
(Crop Science Society of America, 2009-03)Thirty fosmids were randomly selected from a library of Fragaria vesca subsp. americana (cv. Pawtuckaway) DNA. These fosmid clones were individually sheared, and ∼4- to 5-kb fragments were subcloned. Subclones on a single ... -
