Relatedness among species of fungi and higher plants measured by DNA hybridization and base ratios.
HYLOGENETIC relatedness among organisms is reflected in their genotypes. The many efforts to compare genotypes have included comparisons of morphology, physiology, reproduction, and more recently ( MCCARTHY and BOLTON 1963; BOLTON 1966) the hybridization of DNA from different species and genera. These studie; have provided convincing evidence that it is possible to demonstrate relatedness, as j...
متن کاملNanoparticles and higher plants
Nanomaterials and nanotechnology have been widely applied in the world in this last decade. Nanotechnology provides the tool and the technological platforms for the study and transformation of biological systems. Few studies have focused on the effects and mechanisms of nanomaterials on plants. The results of these studies have been reported with the aim to provide further insight into connecti...
متن کاملHigher Plants
Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...
متن کاملRhizosphere communication of plants, parasitic plants and AM fungi.
Plants use an array of secondary metabolites to defend themselves against harmful organisms and to attract others that are beneficial. However, the attraction of beneficial organisms could also lead to abuse by malevolent organisms. An exciting example of such abuse is the relationship between plants, beneficial mutualistic arbuscular mycorrhizal fungi and harmful parasitic plants. Signalling m...
متن کاملThigmo responses in plants and fungi.
Thigmo mechanisms are adaptations that permit a plant to alter growth rates, change morphology, produce tropisms, avoid barriers, control germination, cling to supporting structures, infect a host plant, facilitate pollination, expedite the movement of pollen, spores, or seeds, and capture prey. Through these varied functions, plant thigmo systems have evolved impressive controls of cell differ...
