TLDR
This review extensively analyses the recent advances and challenges in using molecular markers, genomics, transcriptomics, miRNAs and transgenesis for improvement in biotic and abiotic stresses, carbon assimilation capabilities, seed yield, oil content and composition in camelina for biodiesel fuel properties, nutrition and high value-added industrial products like bioplastics, wax esters and terpenoids.Abstract:
Ever-increasing global energy demand, diminishing fossil fuel reserves and environmental concerns have forced to look for renewable and sustainable alternative energy sources preferentially from non-food crops. Camelina being a short-duration, low-cost, non-food oilseed crop with high content of oil (45%) rich in unsaturated fatty acids and capable of growing in marginal lands has emerged as a potential alternative for biofuel (with low carbon emission) and industrial bio-products. However, the fatty acid profile needs to be refined to make it more efficient for biodiesel and bio-products. Attempts to improve crop yield, oil content and composition through conventional and mutation breeding have been limited due to inadequate genetic diversity and availability of mutants. Simple and easy transformation and recent upsurge in ‘omics’ data (trancriptomics and genomics) has resulted in better understanding of lipid biosynthesis and its regulation, and thus has made it possible to produce unusual lipids with modified fatty acids for new functionalities. However, further improvement is still awaited for carbon assimilation efficiency, resistance to various abiotic and biotic stresses, seed yield, oil content and composition. This review extensively analyses the recent advances and challenges in using molecular markers, genomics, transcriptomics, miRNAs and transgenesis for improvement in biotic and abiotic stresses, carbon assimilation capabilities, seed yield, oil content and composition in camelina for biodiesel fuel properties, nutrition and high value-added industrial products like bioplastics, wax esters and terpenoids.read more

TL;DR: The ability to quickly engineer Camelina with novel traits, advance generations, and bulk up homozygous lines for small-scale field tests in less than a year, in the authors' opinion, far outweighs the complexities associated with the crop.

Fueling the future; plant genetic engineering for sustainable biodiesel production
TL;DR: The intent of the present review paper is to review and critically discuss the recent genetic and metabolic engineering strategies developed to overcome the shortcoming faced in nonedible plants, including Jatropha curcas and Camelina sativa, as emerging platforms for biodiesel production.

Genetic mapping of agronomic traits in false flax (Camelina sativa subsp. sativa)
TL;DR: A genetic map for C. sativa was constructed, using amplified fragment length polymorphism (AFLP) markers, in a population of recombinant inbred lines that were developed, through single-seed descent, from a cross between 'Lindo' and 'Licalla', 2 phenotypically distinct parental varieties, to represent a starting point for future marker-assisted breeding.
