NATIONAL: AGRICULTURE : SCIENCE : Indian Institute of Science Education & Research (IISER) Bhopal team conducts Genome Sequencing of Indian Gooseberry Plant (Amla)

Researchers from the Indian Institute of Science Education and Research (IISER) Bhopal have for the first time unravelled the draft genome of the Indian gooseberry plant, popularly known as Amla.

Understanding the genetic composition of Amla can help us understand their origins, evolution, and how they create the biochemicals that are of medicinal value.

While Amla holds significant pharmaceutical and nutritional importance, its genetic composition has hitherto not been studied in detail.

“We analysed the genome and transcriptome of the amla plant using leaves from our campus. We employed advanced sequencing technologies, including 10x Genomics and Oxford Nanopore Technology (ONT) long-read sequencing, along with transcriptomic sequencing,” said lead researcher Dr Vineet Sharma, Associate Professor of Biological Sciences at IISER Bhopal, in a statement.

Amla is a well-known plant indigenous to South Asian countries and has been used in traditional Indian and Chinese medicine and home remedies for centuries.

The stone-fruit of the Amla tree is believed to have high Vitamin C content, in addition to being a rich source of various phytochemicals, minerals, and amino acids. Amla has been thought to be effective in treating conditions like unhealthy levels of fat, Type-2 diabetes, chronic gum diseases, symptomatic knee osteoarthritis, and more.

Apart from obtaining the draft genome structure of the Amla for the first time, the researchers also identified genes responsible for vitamin C biosynthesis and compared them with genes in other plants that bear vitamin C-rich fruits.

The team found that Amla’s exceptional antioxidant power comes from the adaptive evolution of certain genes involved in the production of antioxidants like vitamin C and flavonoids.

Amla’s abundant vitamin C content and the remarkable capacity of each tree to yield up to 100 kg of fruits make it superior to other vitamin C-rich fruits such as the West Indian cherry from Mexico and the camu camu fruit found in Brazil, Peru, Colombia, and Venezuela and makes it a perfect choice for switching from the synthetic to a natural source of Vitamin C.

According to the research team, the adaptive evolution of this plant could be one of the key reasons for its easy adaptation to various climatic zones and environmental conditions.

“The analysis of the whole genomic landscape of the Amla also helped us in understanding its evolutionary descent in comparison with 26 other plant species. It will also help in developing improved nutraceuticals, food, cosmetics, and pharmaceutical products, and for further horticultural and genomic studies,” Dr Sharma said.

The findings have been published recently in the open-access journal, Frontiers in Plant Science.

INTERNATIONAL: FOSSILS DISCOVERY: Dinosaur Nest Cluster with 256  eggs found in Narmada Valley, Madhya Pradesh

While dinosaur nests and eggs having been found in the past, too, this recent find raised the possibility of the Narmada Valley having been a fertile hatchery location for dinosaurs millions of years.

A rare discovery of 92 closely located dinosaur nests and 256 fossilised eggs of herbivorous Titanosaurs (one of the largest known dinosaurs) has been made by a team of palaeontologists in Dhar district, which is part of the Narmada Valley in Madhya Pradesh.

While dinosaur nests and eggs having been found in the past, too, by other palaeontologists in the Jabalpur region of MP and Balasinor in Gujarat, this recent find raised the possibility of the Narmada Valley having been a fertile hatchery location for dinosaurs millions of years ago.

The field research was carried out by a team of palaeontologists from Delhi University, Indian Institute of Science Education and Research, Mohanpur-Kolkata and Bhopal in many villages of Bagh and Kukshi areas of Dhar district between 2017 and 2020.

A paper on their research by Harsha Dhiman, Vishal Verma, G V R Prasad and others was recently published in the PLOS ONE research journal. “A major inference from the three years of research is that the nests and eggs found in the villages of Dhar district date back 66 million years ago.

It’s quite possible that the Titanosaurs either just came to lay the eggs in this area of Narmada Valley or the eggs were also hatched there. The eggs found by us show evidence of hatching as well as not having been hatched,” Dhiman, the lead researcher told this newspaper on Saturday. “Since only nests and eggs and not bones have been found, we need to perform micro CT scan for further research,” Dhiman added.

Egg Diameter around 15-17 cm
The nests found in the Narmada valley were close to each other, which is generally not the case. These nests had eggs which ranged between 15 cm and 17 cm in diameter. “Each nest had between one and 20 eggs,” Dhiman said
