    Notes: Abstract The oxidation behavior of sintered ferritic stainless steel-Al2O3 composites, and composites with ternary additions such as titanium, niobium, or phosphorus, have been studied at 550°C in 1 atm oxygen up to 9 hr. It is found that α-SS-6 vol.% Al2O3 is most resistant to oxidation amongst all the compacts investigated. Amongst the ternary composites, niobium-containing compacts show better oxidation resistance compared to titanium or phosphorus-containing composites.

    Notes: Abstract By differential hybridization, two auxin-inducible cDNA clones (λSAR1 and λSAR2) have been isolated from a cDNA library constructed to poly(A)+ mRNA from auxin-treated strawberry receptacles. Both the clones have been used as probes to study the expression of the auxin-induced genes in pollinated and unpollinated fruits of various stages of development and in different organs. A high level of auxin-induced mRNAs is found in pollinated fruits as compared to unpollinated fruits of the same age, suggesting that the expression of the auxin-induced genes is developmentally regulated and the level of auxin-induced mRNAs is regulated by endogenous auxin. Furthermore, our data on the expression of λSAR1 and λSAR2 genes in pollinated and unpollinated fruits revealed a positive correlation between growth of strawberry fruit and the induction of mRNA corresponding to the λSAR1 and λSAR2 clones. Ethylene has no effect on the expression of the auxin-induced mRNAs. λSAR1 mRNA is not detected in other parts of strawberry plants whereas λSAR2 mRNA is present in roots. Furthermore, mRNA corresponding to λSAR1 and λSAR2 is not detected in other auxin-responsive plant systems such as pea epicotyls and bean explants.
