(1977)A soluble enzyme preparation from the flavedo of Citrus limonum transforms [1-3H1]neryl pyrophosphate or [1-3H1]geranyl pyrophosphate into β-pinene, sabinene, α-pinene, and limonene. The enzyme has been partially purified ...
-
(Facultad de Agronomía e Ingeniería Forestal, Pontificia Universidad Católica de Chile ., 2006-09)The cell wall plays a major role in determining the expansion, growth and shape of plant cells, and thus of the plant itself. Additionally, cell wall breakdown products are used as developmental signals. Moreover, the ...
