Monocotyledonous plants were believed to be not transformable by the soil bacterium Agrobacterium tumefaciens until two decades ago, although convenient protocols for infection of leaf disks and subsequent regeneration of transgenic plants had been well established in a number of dicotyledonous species by then. This belief was reinforced by the fact that monocotyledons are mostly outside the ho...
The biosynthesis of certain benzenoid compounds found in plants, such as the hydroxycinnamic acids, lignin, flavonoids, and coumarins, has recently been actively investigated. In his review (1) on the biosynthesis of these secondary plant products, Neish points out that the results of tracer experiments show the hydroxycinnamic acids to be important precursors in the formation of lignin and oth...
Diel (24 h) leaf growth patterns were differently affected by temperature variations and the circadian clock in several plant species. In the monocotyledon Zea mays, leaf elongation rate closely followed changes in temperature. In the dicotyledons Nicotiana tabacum, Ricinus communis, and Flaveria bidentis, the effect of temperature regimes was less obvious and leaf growth exhibited a clear circ...
