The responses of roots to feeding by larvae of a citrus root weevil (Diaprepes abbreviatus) were investigated in Citrus grandis (L.) Osb. x Poncirus trifoliata (2N) (L.) Raf.; C. grandis x P. trifoliata (4N); P. tirfoliata x C. grandis (Flying Dragon x Nakon; C. paradisi Macf. x P. trifoliata (Swingle citrumelo); C. aurantifolia (Christm.) Swingle (Citrus macrophylla); C. reticulata Blanco (Cleopatra mandarin); C. sinensis (L.) Osb. x P. trifoliata (Carrizo citrange); C. aurantium (L.) (sour orange). Chitinase, chitosanase, B-1,3-glucanase, peroxidase and lysozyme activities were measured and significant differences were observed for some of the cultivars between infested and uninfested rootstocks.Generally, incresead activities were obsrved for chitinase anddecreased activities were observed for the other enzymes measured. Numerous significant differences in hydrolase and peroxidase activities were observed between cultivars. Immunological detection revealed that new protein bands occurred in root potein extracts for six of the cultivars infested with larvae when an antibiody to a class I potato leaf chitinase was used. Antibiodies generated against two citrus chitinases of M, 24 000 (basic chitinase cv. Valencia (C. sinensis) callus, BCVC) and M. 28 000 (basic chitinase/lysozyme cv. Valencia callus, BCLVC)indicated that chitinases in Carrizo were induced in infested roots when the BCVC antibody was imployed. |
