The candidature of 8-bp deletion in badh2 gene as the predominant cause for aroma development in rice was investigated in 84 subsp. indica rice landraces. Presence of this functional mutation was detected in 80 % of aromatic samples and in three non-aromatic landraces which were found to be heterozygous at this locus. However, 11 landraces did not...
Article
The loss of shattering of rice has long been acknowledged as a crucial step sweeping the path of domestication. Here, we collated evidence from genetics, and anthropology to challenge this long-held view. Our discussion dwelt on arguments that (1) undermined the effect of a mutation in the key locus (sh4) which does not always confer non-shattering...

Awn Reduction and the Domestication of Asian Rice: A Syndrome or Crop Improvement Trait? Although wild progenitors of Asian cultivated rice have long awns, they are shorter or absent in domesticated landraces and cultivars. Thus, one may wonder when and why such transition from awned to awnless has occurred, i.e., is the reduction of awns a domesti...

The rice-based agriculture of the Indian subcontinent has been interwoven in the rich socio-cultural fabric of the country. Of which, bio-culturally diverse North-Eastern states nurture thousands of landraces with poorly tapped agronomic traits. In the present study, 27 standard microsatellite data from 171 rice landraces from six states were analy...

Background In India, raw peanuts are obtained by aggregators from smallholder farms in the form of whole pods and the price is based on a manual estimation of basic peanut pod and kernel characteristics. These methods of raw produce evaluation are slow and can result in procurement irregularities. The procurement delays combined with the lack of st...

Bioprospecting is a methodical search for natural ingredients and genes in wildlife that have the potential to be turned into industrial products by biological, genetic, and chemical manipulation and without harming nature. Bioprospecting in cosmetics has made leaps from utilizing plant seeds to fungi, from traditional and herbal cosmetics to vegan...
Thesis
Rice aroma is one of the major economically important rice crop traits which are culturally selected during domestication. The compound underlying this much acclaimed perceptible aroma of rice is 2-acetyl-1-pyrroline (2-AP). Probing into the genetic basis of aroma in rice revealed badh2 to be the candidate gene for expression of aroma. It is situat...

We have evaluated the proto-indica model that is the proponent of multiple domestication of rice but a single origin of the key genes in japonica. Attainment of non-shattering, a marker; appeared least integral to the initial phases of domestication. The other archeological determinants were less discernible in specimens. Existence of the key domes...

Scented rice is an integral part of religious and cultural traditions throughout Asia. Apart from it's interesting genetics and biochemistry, it's role in cultural tradition is described in this article. The role of Silk Routes towards long distance dissemination of aromatic rices from China and Bangaldesh to North-East India is discussed.

Although wild progenitors of Asian cultivated rice have long awns, they are shorter or absent in domesticated landraces and cultivars. Then, one may wonder when and why such transition from awned to awnless has occurred, i.e., is the reduction of awns a syndrome trait or a trait emerged during crop improvement? The proponents of evolutionary model...

The aromatic group of Asian cultivated rice is a distinct population with considerable genetic diversity on the Indian subcontinent and includes the popular Basmati types characterized by pleasant fragrance. Genetic and phenotypic associations with other cultivated groups are ambiguous, obscuring the origin of the aromatic population. From analysis...

Going green is our only route towards a sustainable future. Apart from modern livelihoods, there are several traditional technique based livelihoods, diversification towards which can assist us towards achieving sustainable yet eco-friendly economic growth. The state of Chattisgarh is home to several tribes like Jharas, Ghadwas, Badhais, Murias, an...

This issue has interesting observations on termites, mud-dauber, and bats. In tropical countries like India, termite hillocks have socio-religious relevance but hardly considered as a subject of detailed investigation to understand the social life of insects. Nikita Zachariah in her illustrious article describes this fascinating architectural wonde...

Spatial distribution of potentially toxic metals (PTMs) and their accumulation in mangrove Avicennia officinalis L. were studied along 8 locations in and around Sundarban mangrove wetland, India. Among 8 locations, S3 (Chemaguri) and S5 (Ghushighata) showed higher concentration of PTMs (Cd, Cr, Cu, Ni, Pb, Zn) characterized by higher enrichment fac...

Climate change has profoundly impacted tropical ecosystems, critical for sustaining economies and community livelihoods at local to global scales. Rapid population growth has further negatively impacted natural resource management and upsetting the socio-ecological balance. Sundarbans, world’s largest contiguous tract of mangroves, is not an except...

Kaziranga National Park (KNP), a UNESCO World Heritage Site, harbors one of the last unmodified natural grasslands of Northeast India. The park has proudly been the humble abode of two remarkable megaherbivores, the great Indian rhino and the elephant, and also provides a prime habitat for the Royal Bengal Tiger. It is a haven to various economical...

Asian rice (Oryza sativa L.) is the founding pillar of Indian agro-centric culture. Along with its tremendous economic value, aromatic rice holds a tremendous religious, cultural value in Indian society. Agro-biodiversity of Indian aromatic rice is quite well documented in ancient texts like Charaka Samhita (c. 700 BC), Susruta Samhita (c. 400 BC),...

Question
Most archaeobotanical studies report emphasizes on cereal seeds and pulses to some extent but scarcely about vegetable and fruits. Why? Is there any difference in preservation requirements and if yes please discuss in details about the problems or share publication. Thanks in advance.
Question
Dear all,
 I want to do a non-denaturing DNA-PAGE and I didn't found any info regarding stacking and resolving gel for the purpose in the internet. Do they need, like in protein-PAGE, a stacking gel?
 Thank you!
