Plant Transformation Methods

Plant Transformation Methods Transformation is defined as the process in which the genetic material of an organism is altered by the integration of new genes into its genome. The transformation is done by using vectors such as plasmids. The importance to produce transgenic plants is to: Improve crop yields. Improvement of varietal traits. transgenic plants … Read more Plant Transformation Methods

Plants defense mechanism- structural, histological, chemical

Plants defense mechanism

Plants defense mechanism Plants diseases or phytopathogens affects plants right from the planting stage up to the harvesting and storage of the produce. Consequently, the plants have evolved several different mechanisms by which they defend themselves. These defense mechanisms in plants are termed as “BASAL RESISTANCE”. This term referring to two distinct aspects of plant-pathogen … Read more Plants defense mechanism- structural, histological, chemical

Biological and Chemical control of plant diseases

Biological control of plant diseases 1- Parasitoids One parasitoid attack only on one host, and remain alive as a free-living adult in the host. The size of the parasitoids is the same as the host or may be smaller than the host. Mechanism The female parasitoid lays eggs inside or on the insect host.
