متن کاملRegulation of lysine catabolism in higher plants.
Lysine is an essential amino acid for mammals but its concentration in cereals, one of our main food sources, is low. Research over the past 40 years has unraveled many biochemical and molecular details of the aspartic acid pathway, which is the main route of lysine biosynthesis in plants. However, genetic manipulation of this pathway has not been successful at producing high-lysine seeds. This...

phenolic acids. All of these have inhibitory activity, and most of them produce different biological lesions (EinOur previous work indicated that secalonic acid F (SAF) was the hellig, 1995). major allelochemical produced by Aspergillus japonicus. Studies showed that SAF markedly inhibited the seedling growth of sorghum Secalonic acids, a series of ergochrome pigments, exist (Sorghum vulgare Pe...
متن کاملUpdate on Development Gravitropism in Higher Plants
Since 1806, we have known that plant organs use gravity as a guide for growth (Knight, 1806). The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. It also directs roots to grow downward in soil, where they can reach out to take up the water and mineral ions required for ...
متن کاملFormation of N-acetylglutamate by extracts of higher plants.
The enzymic synthesis of N-acetylglutamate was studied in extracts of higher plant tissues, especially in sugar beet leaves (Beta vulgaris L.). Sugar beet leaves had an enzyme that transferred the acetyl group either from acetyl-CoA or from N(2)-acetylornithine to glutamate. The enzyme was so unstable that special precautions were necessary for its detection and appreciable purification was imp...
