Artificial intelligence in timber forensics employing DNA barcode database.

Unlabelled: Extreme difficulties in species identification of illegally sourced wood with conventional tools have accelerated illicit logging activities, leading to the destruction of natural resources in India. In this regard, the study primarily focused on developing a DNA barcode database for 41 commercial timber tree species which are highly vulnerable to adulteration in south India. The developed DNA barcode database was validated using an integrated approach involving wood anatomical features of traded wood samples collected from south India.

DNA barcoding supports existence of morphospecies complex in endemic bamboo genus Thwaites of the Western Ghats, India.

Thwaites, an economically exploited bamboo genus of the Western Ghats of India is severely affected by unsustainable extraction, natural habitat destruction and endangerment of species resources. This taxonomically challenging genus consists of a genetic mixture of 10 related polyploid species that are difficult to define and classify using traditional morphology. The present study investigated the probability of DNA barcoding using seven standard barcode regions recommended by CBOL as a supplementary tool to define true species boundaries.

DNA barcoding as a valuable molecular tool for the certification of planting materials in bamboo.

DNA barcodes developed for selected commercially important bamboo species can be utilized for the certification of planting stock in bamboo nurseries in absence of discriminatory features at the juvenile stage. Planting materials such as micropropagated plantlets, rhizome transplants and culm cuttings, generated at nursery level are directly procured for establishment of commercial plantations without any further verification Very often misidentification and mixing up occur at nursery level and the error is not discovered until several years have passed. The present study evaluated the potentiality of seven Consortium for Barcode of Life (CBOL) recommended standard DNA barcode regions in commercially important bamboo species of India.
