Harvesting grapes at the appropriate maturity is key to production of high quality red wines. Viticulturists, oenologists and winemakers define several types maturity: technological, phenolic aromatic. Aromatic probably most important for determining wine typicity, including terroir expression. This article (part I) reviews state-of-the-art compounds underpinning aromatic maturity; influence fa...
Phenylalanine, tyrosine, and tryptophan were taken up into cells of Escherichia coli K-12 by a general aromatic transport system. Apparent Michaelis constants for the three amino acids were 4.7 x 10(-7), 5.7 x 10(-7), and 4.0 x 10(-7)m, respectively. High concentrations (> 0.1 mm) of histidine, leucine, methionine, alanine, cysteine, and aspartic acid also had an affinity for this system. Mutan...
Some avian species incorporate aromatic plants to their nests. The "nest protection hypothesis", which posits that volatile secondary compounds contained in these plants may have antiparasite properties, has not received full support. All previous tests of this hypothesis have only considered effects on nest-dwelling ectoparasites, but not on blood-sucking flies. The "drug hypothesis" posits th...
Rice landraces are lineages developed by farmers through artificial selection during the long-term domestication process. Despite huge potential for crop improvement, they are largely understudied in India. Here, we analyse a suite of phenotypic characters from large numbers of Indian landraces comprised of both aromatic and non-aromatic varieties. Our primary aim was to investigate the major d...
