Ilish’s genomes contain 7.8 million of nucleotides, which is 1/4 of human’s genome

Scientists from Bangladesh Agricultural University (BAU) in Mymensingh have uncovered the genome sequence of the much-loved Ilish fish.

Fisheries and Biology Department Professor and Genome Sequencing and Assembly Team Coordinator Dr Md Shamsul Alam on Saturday at a press conference, said after three years of research, they finally succeeded. 

The members of the team also include Poultry Science Professor Md Bazlur Rahman Mollah, Biotechnology Department Professor Md Shahidul Islam and Fisheries Department Professor Md Golam Kader of the university. 

Dr Shamsul said: “On receiving the geographical indication (GI), the research work started in December 2015, to find the “Reference Genome Preparation,” establish a “Genome Database” and to determine the number of genes. After three years of research, we were able to uncover the full life mystery of Ilish, for the first time.”

He further said: “Genome is the whole life provision of a living organism. Birth of an animal, growth, reproduction and biological activities, including adaptation to the environment, are carried out through the genome.

“Ilish’s genomes contain 7.8 million of nucleotides, which is 1/4 of human’s genome.”

Dr Shamsul said: “Through Ilish genome reference, answers to many unknown questions can be easily found. It is also possible to ensure the sustainability of Ilish from this. 

“Besides, it is easy to determine where and how many sanctuaries should be established in the country for Ilish. It can also be identified whether our Ilish is distinct from that of other countries’.”

Ilish’s full-fledged D-Novo-Genome assembly was ready on July 31, 2017, after it started in December 2015.

On August 25, 2017, the information of the complete Histology of Genomic Sequence of Ilish was submitted to the International Genome Database National Centre for Biotechnology.

The results of the research on the genome of the species were presented in two international conferences as well.
