Supply of superior quality tissue cultured plants of species in demand
Available at: MTP, TERI, Gual Pahari and
MTP, NCL, Pune As conventional methods of propagation are insufficient
to meet the existing demand of planting material, large-scale in vitro
multiplication at these facilities offers a major advantage. The plants
produced here are disease-free, can be produced en masse and without any
dependence on season. Also, superior genotypes (elites) with high yields/disease-resistance
can be supplied by this facility.
Contractual research/production of plants on request by an individual
or a company
Available
at: MTP, TERI, Gual Pahari All plant species are not regularly produced at
the facility but protocols for the micropropagation of a large number
of species are available. Plants can be produced on request from companies/individuals
in desired quantities.
Inoculation of tissue cultured plantlets with
efficient mycorrhizal strains, helping in better productivity and establishment
of plants.
Available at: MTP, TERI, Gual Pahari The survival rate and yield of plants raised by
tissue culture is improved when mycorrhizae are applied; this service
can be of great help to progressive farmers and private growers.
Aftercare of tissue cultured plants in the field provided to harness maximum
gains
Available at: MTP, TERI, Gual Pahari The planting material’s aftercare is of utmost
importance to its survival and the MTP provides this information to its
clients. However, if the need should arise, experts can provide solutions
or even visit the field trial site.
Help to entrepreneurs in setting up laboratory/greenhouses,
and transfer of technology for immediate execution.
Available at: MTP, TERI, Gual Pahari This includes designing of the laboratory, selection,
purchase and installation of the equipment, training of manpower, etc.
For example, TERI has signed an agreement with the Forest Department of
Tripura under which the former’s Micropropagation Technology Park
will help the Tripura Forest Department set up a tissue culture facility
in Agartala, Tripura. The project is being implemented virtually on a
turnkey basis covering most aspects of production through tissue culture.
Support to the tissue culture industry for virus
diagnosis of tissue cultured plants
National Facility for Virus Diagnosis
and Quality Control of Tissue Culture Raised Plants This involves testing of plants produced
in vitro for the presence of viruses to ensure that only (a) virus-free
mother plants are used for micropropagation, and (b) virus-free and quality-tested
tissue culture plants are supplied to growers. This would minimize the
risk of inadvertent introduction and subsequent spread of viruses thereby
ensuring the quality of plants. This will be achieved by developing a
virus diagnosis programme based upon biophysical, immunological, and molecular
techniques. Careful indexing based on recent biotechnological methods
such as immunoprobes, nucleic acid probes, and polymerase chain reaction
(PCR) assay would ensure phytosanitary safety during the movement of planting
materials. The testing protocols will detect known viruses and unknown
viruses. The viruses for which diagnostic probes (antibodies and cDNA
probes) have been developed are known to infect plant species such as:
banana, brinjal, cassava, citrus, frenchbean, garlic, gladioli, groundnut,
mungbean, onion, rice, soybean, sugarcane, tobacco, tomato, urdbean, lily
and some ornamental plants.
Quality testing of tissue culture raised plants
for assuring clonal fidelity
National
Facility for Virus Diagnosis and Quality Control of Tissue Culture raised
Plants In order to minimize the risk of introducing somaclonal
variability, tissue culture-raised plants need to be thoroughly checked
for their clonal character. Molecular testing ensures this quality. With
the advent of the PCR technique and DNA-based molecular markers, expertise
has been developed for the assessment of genetic diversity, phylo-genetic
analysis, varietal typing and establishing the true-to-type of tissue
cultured plants. Results have demonstrated that even though RFLP and RAPD
markers are useful in studying both intra- and inter-specific variation,
the extent of polymorphism generated by AFLP markers is several times
higher. Hence, AFLPs may be the method of choice for discriminating very
closely related genotypes (such as the micropropagated plants) as compared
to other molecular markers.
