    Notes: Abstract Larval cuticle ofHelicoverpa (Heliothis)zea and yeast extract added to a minimal medium (MM) induced germination of conidia ofNomuraea rileyi whereas sterile distilled water or MM alone did not. Yeast extract increased mycelial yield, but when cuticle was added, mycelial yield significantly decreased. Proteases and chitinases ofN. rileyi were only expressed when cuticle was added to the MM.

    Association of two measures of vegetative growth rate with other traits in inter and intraspecific matings of oats (1986)

    Notes: Summary F2-derived oat lines from inter (Avena sativa L. x A. sterilis L.) and intraspecific (among A. sativa cultivars) matings were evaluated in the F3, F4, and F5 generations for heading date, grain and straw yields, biomass, vegetative dry weight at anthesis, vegetative growth rates until anthesis (GRA) and until maturity (GRM), and harvest index. The associations of GRA and GRM with harvest index ranged from zero to slightly negative. The positive correlations of GRA and GRM with grain yield were stronger in inter than in intraspecific matings. Grain yield was positively associated with harvest index in both inter and intraspecific matings. The results suggest the use of A. sterilis x A. sativa matings to improve vegetative growth rate, grain yield, and, to a certain extent, harvest index simultaneously without affecting the growth duration of the crop.

    Effects of cuticle source and concentration on expression of hydrolytic enzymes by an entomopathogenic fungus,Nomuraea rileyi (1993)
    Springer
    Mycopathologia 122 (1993), S. 149-152

    Notes: Abstract The effects of cuticle from larvae ofTrichoplusia ni andHelicoverpa (=Heliothis)zea on expression of proteases and chitinases by germinating conidia ofNomuraea rileyi in submerged cultures were studied. Increasing the concentration ofT. ni orH. zea cuticle resulted in a 13- and 15-fold increase in protease activity, respectively. Endochitinase and N-acetylglucosaminidase activity on theT. ni andH. zea substrates increased as cuticular concentrations increased to 2.5%, then stabilized or decreased thereafter. The simultaneous expression of both proteases and chitinases suggests that they are controlled by a multiple-regulatory system.
