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.

TL;DR: Early- to mid-April is the best-planting window for optimum spring camelina stands and seed yield in this environment after heat stress in the growing season and increase in precipitation amounts improved seed yield, oil, PUFA, and linolenic acid concentrations.

The Prospect of Using Cyanobacterial Bicarbonate Transporters to Improve Leaf Photosynthesis in C3 Crop Plants
TL;DR: The photosynthetic CO2-fixing enzyme Rubisco arose some 3.5 billion years ago, in an environment when CO2 was high and oxygen (O2) was low, and under these conditions it was CO2 saturated and presumably performed well.

TL;DR: There is compelling evidence for triplication of the C. sativa genome, including a larger chromosome number and three-fold larger measured genome size than other Camelina relatives, three isolated copies of FAD2, FAE1, and the KCS17-FAE1 intergenic region, and three expressed haplotypes observed for six predicted single-copy genes.
