In this article we will discuss about the translocation of organic substances in phloem. An organised transport system is essential for the efficient functioning of different organs in a multicellular plant. Nutrients were absorbed from the soil through the roots and are utilized in rest of the organs of the plant. Similarly, metabolites are synthesized in the leaves and are [...]
In this article we will discuss about:- 1. Origin of Translocation 2. Types of Translocation 3. Effects. Origin of Translocation: Translocations can originate in the following different ways: (i) Translocations may originate spontaneously. (ii) They may be induced by mutagens, viz., ionizing radiations and many chemical mutagens, since they induce chromosome breakage. (iii) Translocations may be induced by growing plants [...]
The following points highlight the top fifteen uses of translocation in genetics. The uses are: 1. Study of chromosome behaviour during meiosis 2. Assignment of centromere position 3. Interchanges as genetic markers 4. Determination of unknown locus of a gene and chromosome mapping 5. Association of linkage groups or genes to specific chromosomes and a Few Others. Uses of Translocation [...]
