in agrobacterium , the chva and chvb loci are known to be essential for oncogenic transformation of dicotyledonous plants and for attachment to plant cells [ douglas , c. j. , staneloni , r. j. , rubin , r. a . & nester , e. w. ( 1985 ) j. bacteriol . 64 , 102-106 ] , and the chvb locus has been implicated in the production of ( 1 -- > 2 ) -beta-glucan , a unique exopolysaccharide component [ puvanesarajah , v. , schell , f. m. , stacey , g. , douglas , c. j . & nester , e. w. ( 1985 ) j. bacteriol . 164 , 102-106 ] .
