Freeze resistance is critical to successful dormant bud (DB) cryopreservation, and affected by genotype, environmental conditions, dormancy phase processing techniques. Pretreatment induced freeze may contribute more efficient protocols for cryopreserving DB. Differential thermal analysis (DTA) was used quantify the effects of cryopreservation pretreatments on budwood. Low temperature exotherm ...

Crown gall of walnut (Juglans sp.), caused by the bacterium Agrobacterium tumefaciens, greatly impacts the CA walnut industry. To determine the genetic diversity of A. tumefaciens throughout the Central Valley of CA, we collected isolates from 12 walnut growing counties. A total of 340 A. tumefaciens biovar 1 isolates were collected and tested for the presence of the Ti plasmid by PCR; 267 isol...
