“…Parasite plant explants could include callus, embryos, seedlings, plantlets, isolated organs, or parts of organs (42). Current research in our laboratory is focused on producing callus of dwarf mistletoe, Arceuthobium tsugense, which can then be challenged with fungi as part of in vitro screening for potential biocontrol agents (41,123).…”

Parasitic flowering plants from 23 genera in 7 families (Convolvulaceae, Lauraceae, Loranthaceae, Orobanchaceae, Santalaceae, Scrophulariaceae and Viscaceae) have been cultured in vitro. These plants include both hemiparasites and holoparasites that parasitize stems and roots of angiosperms and gymnosperms. This review highlights relevant information on each genus with regard to its biology, distribution, host range, and tissue culture procedures. Tissue culture has been used to study aspects of the development, metabolism, reproduction, physiology and nutritional requirements of these plants under controlled conditions. Studies of host-parasite relationships, including potential roles of signals/receptors that influence host development and physiology, and factors influencing seed germination and haustorium formation, have been conducted. The effects of chemicals and herbicides on the physiology and biochemistry of parasite embryo and seedling development have been studied, as well as tile influence of inhibitors or stimulants on seed germination. Tissue culture has provided a method for propagation and genetic improvement of plants with commercial value.

“…An important application of in vitro studies is the investigation of plant defense mechanisms. The use of tissue cultures for studying tree defense mechanisms has been the subject of several reviews (AMERSON and MoTT 1982; DINER and KARNOSKY 1987; OSTRY and SKIEEING 1992). Most of the previous research using these systems for diseases of coniferous trees has centred on the interactions between pines and rust fungi (JACOBI 1982;GRAY and AMERSON 1983;DiNER and MoTT 1984), whereas relatively little work has been undertaken on responses to root pathogens.…”

Glucanohydrolase enzyme activity in embryos of Scots, Corsican and lodgepole pines infected in vitro with Heterobasidion annosum

Embryos of Scots pine {Pmus sylvestris), Corsican pine {P. mgra var. maritima) and Lodgepole pine (P. contorta) were infected in vitro with Heterobasidion annosum and the activities of l,3-/i-glucanase, chitinase and ^-glucosidase were monitored. Both the infected and control embryos of the three pine species showed the presence of the enzymes. Statistical analysis showed no significant increase (P > 0.05) in the levels of l,3-i5-glucanase in infected embryos for all the three pine species. However, there was a significant increase in levels of chitinase in infected embryos of P. contorta and P. nigra var. maritima and also in levels of /J-glucosidase in infected embryos of all three of the pine species. The study has therefore revealed that constitutive levels of glucanohydrolase enzymes exist in the embryos of the three pine species and that the induction of chitinase and /^-glucosidase was a factor in the response of the embryos to stimulation by H. annosum infection.

“…The utility of in vitro generated callus in studies of plant responses to infection has been demonstrated in a number of host-parasite systems. In forest tree pathology, particularly valuable systems have been described over the past 15 years and a number of review articles which usefully summarize this approach are available (AMERSON and MOTT 1982;DINER and KARNOSKY 1987;OSTRY and SKILLING 1992). Particular attention has been focused on the development of in vitro techniques for testing the resistance of pines to Cronartium spp.…”

Responses of Cupressus and Chamaecyparis callus tissues to inoculations with Seiridium cardinale

Inoculations of callus generated from micropropagated shoots of Cupressus sempervirens, Cupressus macrocarpa, Cupressus torulosa and Chamaecyparis lawsoniana showed that callus of species resistant or relatively resistant to Seiridium cardinale supported significantly less surface growth of the pathogen than callus of susceptible species. In dual cultures of Cupressus sempervirens or Cupressus torulosa callus with S. cardinale, inhibition of fungal growth toward^s the callus was correlated with known field resistance of these host species. Lignification, accumulation of polyphenohcs and possible suberization of cell walls were detected in inoculated callus. This response was also correlated with known field resistance of the tested host species.
