Within-population variation in susceptibility to Agrobacterium tumefaciens A281 in Picea abies (L.) Karst

The purpose of this study was to investigate the genetic variation of susceptibility to Agrobacterium within a Picea abies population. Tumor formation was studied in 16 open-pollinated families belonging to a central Swedish population of Picea abies. Strain A281 of Agrobacterium tumefaciens was use...

Description
Summary:The purpose of this study was to investigate the genetic variation of susceptibility to Agrobacterium within a Picea abies population. Tumor formation was studied in 16 open-pollinated families belonging to a central Swedish population of Picea abies. Strain A281 of Agrobacterium tumefaciens was used to infect 3-monthold seedlings in a five-block greenhouse experiment. The analysis of variance showed strong significance for the between-family variation of tumor-formation percentages, varying from 28% to 73%. The most susceptible material will be suitable for experiments on the production of transgenic plants in vitro using disarmed Agrobacterium strains.
