Comparative transcriptomics reveals potential regulators of climate adaptation in L. (Indian Sandalwood).

Unlabelled: L. (Indian Sandalwood), a valued tree species known for its fragrant heartwood and essential oil is facing increasing threat due to severe anthropogenic pressures compounded by climate change which has resulted in depletion of its adaptive gene pool. The present study investigates the transcriptome-level responses of nine sandalwood genotypes sourced from diverse climatic zones to identify adaptive genes in the species.

Assessment of seed- and seedling-related traits in (Indian sandalwood) reveals high adaptive potential.

Seed and seedling traits govern plant fitness and persistence and are influenced by the interaction between the plant and its environment. Changing climatic and edaphic conditions will drastically affect early fitnessrelated traits and can alter the demography and species distribution range. It is widely documented that trait variation among populations may increase resilience of tree communities and reduce the risk of extinction under future climates.

Integrated mRNA and small RNA sequencing reveals post-transcriptional regulation of the sesquiterpene pathway in L. (Indian sandalwood).

Key Message: In sandalwood, negative pattern of regulation by miRNAs was documented in key genes from the sesquiterpene pathway, with cytochrome P450 reductase showing maximum miRNA targets, followed by sesquisabianene synthase 1.

Abstract: A comprehensive knowledge of the molecular regulation of sesquiterpene biosynthetic pathway through transcriptomic studies is well established in (Indian Sandalwood). However, the post-transcriptional regulation of the genes regulating the pathway is still elusive in this genus.

The draft genome reveals early duplication event in Pterocarpus santalinus: an endemic timber species.

A 541 Mb draft genome of Pterocarpus santalinus is presented and evidence of whole-genome duplication in the Eocene period with expansion of drought responsive gene families is documented. Pterocarpus santalinus Linn. f.

Bio-prospecting of cuttle fish waste and cow dung for the production of fibrinolytic enzyme from Bacillus cereus IND5 in solid state fermentation.

The process parameters governing the production of fibrinolytic enzyme in solid state fermentation employing Bacillus cereus IND5 and using cuttle fish waste and cow dung substrate were optimized. The pH value of the medium, moisture content, sucrose, casein and magnesium sulfate were considered for two-level full factorial design and pH, casein and magnesium sulfate were identified as the important factors for fibrinolytic enzyme production. Central composite design was applied to investigate the interactive effect among variables (pH, casein and magnesium sulfate) and response surface plots were created to find the pinnacle of process response.
