    Applications of high-temperature superconductors to the power sector in developing countries (1988)

    Notes: Abstract Developing countries imported power equipment worth US$25 billion in 1986, and their power requirements are expected to rise well into the 21st century. Therefore, a global view needs to be taken while according priorities for superconductivity research to the power sector. The scale of the power applications, feasibility of which is earlier established for low temperature superconductors, may have to be reduced if they have to be relevant for the developing countries (e.g., superconducting power generators of 100–500 MW, storage of 500–2000 MWh, and transmission lines of about 100–400 KVA). Fortunately, due to the easier availability of coolant (LN) and ceramics, there could be greater efforts in R & D and, therefore, faster progress.

    Chalcone synthase in rice (Oryza sativa L.): Detection of the CHS protein in seedlings and molecular mapping of the chs locus (1996)
    Springer
    Plant molecular biology 32 (1996), S. 735-743

    ISSN: 1573-5028
    Keywords: chalcone synthase cDNA (chs cDNA) ; RFLP ; anthocyanins ; flavonoids ; synteny

    Topics: Biology
    Notes: Abstract The chalcone synthase is a key enzyme that catalyses the first dedicated reaction of the flavonoid pathway in higher plants. The chs gene and its protein product in rice has been investigated. The presence of a chalcone synthase (CHS) protein in rice seedlings and its developmental stage-specific expression has been demonstrated by western analysis. The chalcone synthase of rice was found to be immunologically similar to that of maize. A rice cDNA clone, Os-chs cDNA, encoding chalcone synthase, isolated from a leaf cDNA library of an indica rice variety Purpleputtu has been mapped to the centromeric region of chromosome 11 of rice. It was mapped between RFLP markers RG2 and RG103. RG2 is the nearest RFLP marker located at a genetic distance of 3.3 cM. Some segments of chromosome 11 of rice including chs locus are conserved on chromosome 4 of maize. The markers, including chs locus on chromosome 11 of rice are located, though not in the same order, on chromosome 4 of maize. Genetic analysis of purple pigmentation in two rice lines, Abhaya and Shyamala, used in the present mapping studies, indicated the involvement of three genes, one of which has been identified as a dominant inhibitor of leaf pigmentation. The Os-chs cDNA shows extensive sequence homology, both for DNA and protein (deduced), to that of maize, barley and also to different monocots and dicots.
