Inoculation with a compatible race of P. infestans has been reported to inhibit the accumulation of sesquiterpenoid phytoalexins in response to a second inoculation with an incompatible race. > Water soluble glucans containing 17-23 glucose residues with predominately B 1-3 linkages and minor amounts of 3 1"6 branches have been obtained from mycelial extracts of P. infestans. zoosporesg d germination fluids of...

Thiourea and allylthiourea (20), D-xylulose (22), sodium diethyldithiocarbamate, L-methionine, and -propyl-di- -propylthiol-carbamate (163), 12 6-(substituted) purines (166), and two coumarin derivatives (164) have been found to promote Striga seed germination. None of these materials, however, appear to be constituents of the natural stimulant preparations.

SASPs comprise about 10-20% of the protein in the dormant spore, exist in two forms alfi and y) d are degraded during germination. They are essential for expression of spore resistance to ultraviolet radiation and also appear to be involved in resistance to some biocides, e.g. hydrogen peroxide. Spores (a /3 ) deficient in a//3-type SASPs are much more peroxide-sensitive than are wild-type (normal) spores. It has been proposed that in wild-type spores DNA is saturated with a/j3-type SASPs and is thus protected from free radical damage. 

Flax seeds were placed for germination on moist paper for three days at 22°C and in the dark then, the plantlets were transferred under continuous white light on a liquid culture medium, as previously described [6], Suspension-cultured cells of flax were obtained from hypocotyl-derived calli as described by Schaumann et al. [4] and cultured on a medium described by Murashige and Skoog [7] containing kinetin (0.75 mg 1 ) and 2-4 D (0.2 mg 1 ).

Protocol updated from Krolak et al. (49) and Dashek and Mills (50). Controls (a) Germinate pollen without [14C]-pro and process as before, (b) Construct a radioautographic sandwich with collodion lacking pollen, (c) Expose a slide coated with Kodak NTB-2 Nuclear Track Emulsion to light and develop emulsion with D-19. (Sample autoradiographs are presented in Fig. 3.)...
