DNA EXTRACTION
Fresh tissue samples of caudal fin, pectoral fin, dorsal fin or muscle were
dissected and preserved in 95% ethanol (EtOH). Total genomic DNA was
extracted following a minor modified version of the salting out protocol
described by Miller et al. (1988).

Steps Involved:-
Tissue stored in ethanol was washed with TRIS buffer (pH 8.0) by spinning
Tissue sample was placed directly into 500 μl of Solution 1; in a 1.5 ml
eppendorf tube
After the addition 5 μl of Proteinase K (20mg/ml) samples were incubated
at 55°C in water bath for 2 hours for digestion (with occasional mixing).
Sample was chilled on ice for 10 minutes to deactivate enzyme activity.
250ml of solution 2 was added and tubes were inverted several times to
mix.
Sample was then chilled on ice for a further 5 minutes.
The sample was then spun at 8000 rpm for 15 minutes at 4ºC to pellet
cellular debris and Nacl.
About 500 ml of the clear supernatant was carefully collected into a new-
labeled 1.5 ml eppendorf tube with wide-bore filter tip.
If the supernatant was not clear
Appendix
203
To precipitate the DNA from this solution twice the volume of 100% AR
grade ethanol was added and left overnight at -20°C.
The next day spinning was done at 11,000 rpm for 15 minutes at room
temperature to pellet the DNA.
The supernatant was completely removed before DNA pellet was rinsed
with 250ml of cold 70% ethanol.
Spinning was done at 11,000 rpm for 5 minutes at room temperature
and the supernatant was again carefully discarded and DNA was left to
dry with lid off at room temperature.
Partially dried DNA was then resuspended in 50-200ml (depending on
the size of the pellet) of TE Buffer (pH-8) by gently pipetting sample with
wide-bore filter tip until dissolved before storage at –20°C for further
use.

2.5 ml of Ethidium bromide (EtBr) was added before cooling down to
50°C (Approx.) and poured into the gel casting plate (Capacity 30 ml)
with already adjusted gel comb.
Appendix
205
The solution was let to solidify at room temperature for half an hour for
the gel to set.
The gel was placed in the electrophoresis unit.
Cold 1 x TBE was used as gel running buffer (electrolyte) in the
electrophoresis unit.
2-5 ml of DNA solution mixed with 2 ml of gel loading buffer was loaded
in each wells
The gel was run at constant voltage 90 V for 20 to 30 minutes.
After electrophoresis the gel was visualized under UV transilluminator
and the image was captured and documented using ImageMaster VDS
(Pharmacia Biotech, USA).

PCR Sequencing and Clean-up Protocol
Test RUN AND PCR CLEAN-UP
Verification of successful amplification was assessed by agarose gel
electrophoresis. 5 ml PCR product (1-2 ng ml-1
) (Sambrook et al., 1989; White
& Wu, 2001) mixed with 2 ml of gel loading buffer was then run on 1.8% agarose
gel (10 x 4 cm) stained with 2.5 μl EtBr (0.5μg/ml) in 1X TBE buffer (pH 8.0) at
constant voltage of 90V for one hour to check the amplification of the specified
gene. A molecular weight standard ladder was also included in one of the wells
on each agarose gel. The gel was visualized under UV transilluminator and the
image was captured and documented using ImageMaster VDS (Pharmacia
Biotech, USA).
Successfully amplified product was cleaned using GeNeiTM Quick PCR
purification kit (Genei, Bangalore, India) following the manufacturer’s
instructions. After clean-up product was again run on 1.8% agarose gel to check
recovery rate of clean-up procedure.
SEQUENCING PCR PROTOCOL
The recipe for sequencing reactions of clean PCR product with PTC 200
gradient thermal cycler (M.J. research, Inc., Watertown, Massachusetts, USA)
was as follows:
Reaction mixture:-
Components Volume Per Reaction
Template DNA (10 –20 ng/μl) 1.0 μl
Double distilled sterile water 5.8 μl
BigDye Sequencing Buffer (1X dilution) 1.5 μl
Primer (forward or reverse; 10 pmol/ml) 0.7 μl
BigDye Terminator Mix Version 3.1TM
1.0 μl
Total Volume 10.0 μl
Appendix
207
Sequencing PCR conditions:-
Steps Temperature Time Cycles
Denaturation 95°C 30 seconds
Annealing 50°C 5 seconds 24
Extension 60°C 4 minutes
Soak 4°C 3
Sequencing Clean-up:-
The resulting cycle sequencing fragments were cleaned up by Ethanol
precipitation protocol as follows:-
2.5 ml of 0.5M EDTA was taken and volume was made upto 10 ml by
adding Double distilled water to make 125 mM EDTA.
2μl of 125 mM EDTA (freshly prepared) was added to each tube containing
the sequencing PCR product
Total volume was adjused to 100μl by adding double distilled (autoclaved)
water and mixed well.
The entire content of the sequencing reaction was transferred into a 1.5
ml eppendorf tube and 10μl of 3M sodium acetate (pH 4.6) was added to
each tube.
250μl of 100% chilled ethanol was added and mixed gently.
The mixture was incubated at room temperature for 15 minutes.
The tubes were spun for 20 minutes at 12,000 rpm at room temperature
with hinge of the tubes facing out (DNA pellet will be on this side).
Appendix
208
All the supernatant was immediately aspirated off avoiding the pellet.
Opposite the hinged side was aimed, which was opposite the pellet.
Pipetting was started from the top of the solution, aspirating slowly
downwards.
250 μl of 70% chilled ethanol was added.
Spinning was done for 5 minutes at 12,000 rpm with tubes in the same
orientation as previous spin.
All the supernatant was carefully and completely aspirated off.
The above steps of 70% ethanol wash was repeated twice.
The supernatant was decanted and the pellet was air dried for 30-45
minutes on heating block at 45°C
The tubes with DNA were wrapped in aluminium foil and stored at 4°C
until they were transported to the sequencing facility in light-proof
conditions.

The increasing global loss of biodiversity has led to numerous proposals to intensify the efforts to produce a census of all biological diversity and to modernize the taxonomy.
DNA barcoding data plays an important role in ichthyologic diversity assessment, management and conservation which helps in construction of a comprehensive, consistent reference library of DNA sequences and development of economical technologies for species identification at national and international level.
Perciformes is the largest and the most diversified of all finfish orders containing about 9300 species. About 80 species are recorded from freshwaters of Indian region. Despite the abundance of perciforms and their commercial and scientific importance, the classification and phylogeny of this group remain extremely confused (Nelson, 2005).
The present study is aimed to generate species-specific DNA signatures for accurate documentation of freshwater perciform diversity, its sustainable utilization and management and to resolve taxonomic disputes.
Introduction
Material and Methods
Results and Discussion
Identified specimens (Total 40 species; 5 specimens each) were collected from different drainages in India and preserved with 95% ethanol.
Total genomic DNA was extracted from the collected tissue samples (muscle/fin) using salting out method (Miller et al., 1988).
Partial sequence information of mitochondrial COI (655bp), Cyt b (800bp) and 16S rRNA (560bp) genes of fishes were generated using primers given in the table 1.
The raw DNA sequences were aligned and edited using BIOEDIT (version 7.0.5.2; Hall, 1999). Phylogenetic and molecular evolutionary analyses were made using MEGA version 3.1 (Kumar et al., 2004). Fstand its significance were calculated using ARLEQUIN version 3.01(Excoffier et al., 2005).
The K2P pair-wise genetic divergence values between species ranged from 3.58 to 31.36 % (COI); from 4.19 to 31.69 % (Cyt b) and from 2.21 to 21.34% (16S rRNA).
The mean within species genetic distance values were 0.68% (COI); 0.59% (Cyt b) and 0.30% (16S rRNA) except for two species.
Phylogenetic relationships based on morphological characters and molecular data were generally concordant and all the species were partitioned into distinct entities without any haplotype sharing or overlapping. Congeneric species always clustered together and so did the confamilial species.
High genetic divergence and significant Fst values (P<0.01) in Anabas testudineus collected from Kerala, Andhra Pradesh and Orissa and Pristolepis marginata from 2 locations in Kerala indicate occurrence of unrecognized cryptic species; and further taxonomic and genetic investigations are recommended.
It is concluded that partial sequence information of the three mitochondrial genes- COI, Cyt b and 16S rRNA can be used as diagnostic tools for unambiguous identification of the freshwater perches of the Indian region with applications in its management and conservation.
