Anilides and phenylureas: correlation between calculated pi-electron structure and inhibition of photosynthesis.

Abstract

25 , and saturated ammonium sulfate-M sodium acetate-isopropyl alcohol (80:18:2). 26 Uracil dimers made in ice differ from those found in the polynucleotide in that 50% of them are decomposed by formic acid hydrolysis. The remainder of the dimers are not destroyed by further hydrolysis-a result indicating that the dimer made by irradiating uracil in ice is not homogeneous in structure.

Effect of linuron and dinosebacetate onVicia faba-Rhizobium leguminosarumsymbiosis

“…linuron, showed an indirect effect on the nitrogenase activity of the nodule bacteria. The urea herbicides are known to block the photosynthetic activity of the plant (Ashton 1965;Brain 1965;Karmin et al 1965;Jordan et al 1966). As nodule bacteria live in symbiosis with legume plants, their activity could have been influenced by the negative photosynthetic effect of linuron.…”
