Intersectional crosses between species of sections Aigeiros (Populus deltoides, P. X euramericana or P. nigra) and Leuce (P. alba or P. tremuloides) are known to be reciprocally incompatible. The site of pollen tube arrest is on the stigma surface in pollinations between pistils of section Leuce and pollen of section Aigeiros; tubes failed to penetrate the stigma surface. In reciprocal matings,...

1. When chick-embryo cells were treated with ultraviolet-inactivated influenza virus (Melbourne strain), interferon was produced after a lag period of about 10hr. 2. The addition of small amounts of either puromycin or p-fluorophenylalanine immediately after the virus inhibited the subsequent production of interferon. Both inhibitors primarily affected protein synthesis, and it is concluded tha...

l-2,5-Dihydrophenylalanine is extensively incorporated as a phenylalanine analogue into cell proteins. Phenylalanine-requiring Escherichia coli ATCC 9723f and sarcoma 180 grow at normal rates initially with the analogue and maximally replace 65 and 33%, respectively, of phenylalanine in the peptide residues of their cell protein without death. With the analogue alone growth of E. coli becomes n...

The effects of chloramphenicol and p-fluorophenylalanine (p-FPA) on growth, proportion of motile cells, average rate of motility, and the chemotactic response of a methionine auxotroph of Escherichia coli K-12 were studied. Kinetic studies revealed that the inhibition of chemotaxis by p-FPA can be explained by the effect on growth, proportion of motile cells, and average rate of motility rather...

Seed germination is considered a critical phase in plant development and relatively sensitive to heavy metals. White poplar (Populus alba) trees tend to accumulate Cd and Zn in their tissues. We tested if soil contamination can affect P. alba progeny, reduced seed germination and explored the distribution of mineral elements in the seed. For this purpose, fruits and seeds from female P. alba tr...

CYP83B1 from Arabidopsis thaliana has been identified as the oxime-metabolizing enzyme in the biosynthetic pathway of glucosinolates. Biosynthetically active microsomes isolated from Sinapis alba converted p-hydroxyphenylacetaldoxime and cysteine into S-alkylated p-hydroxyphenylacetothiohydroximate, S-(p-hydroxyphenylacetohydroximoyl)-l-cysteine, the next proposed intermediate in the glucosinol...
