Direct massively parallel sequencing of SARS-CoV-2 genome was undertaken from nasopharyngeal andoropharyngeal swab samples of infected individuals in Eastern India. Seven of the isolates belonged to the A2aclade, while one belonged to the B4 clade. Specific mutations, characteristic of the A2a clade, were alsodetected, which included the P323L in RNA-dependent RNA polymerase and D614G in the Spike glycoprotein.Further, our data revealed emergence of novel subclones harbouring nonsynonymous mutations, viz.G1124V in Spike (S) protein, R203K, and G204R in the nucleocapsid (N) protein. The N protein mutationsreside in the SR-rich region involved in viral capsid formation and the S protein mutation is in the S2 domain,which is involved in triggering viral fusion with the host cell membrane. Interesting correlation was observedbetween these mutations and travel or contact history of COVID-19 positive cases. Consequent alterations ofmiRNA binding and structure were also predicted for these mutations. More importantly, the possibleimplications of mutation D614G (in SD domain) and G1124V (in S2 subunit) on the structural stability of Sprotein have also been discussed. Results report for the first time a bird’s eye view on the accumulation ofmutations in SARS-CoV-2 genome in Eastern India.

To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".
Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.
Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.
Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
