Interactions between Camelina sativa (Brassicaceae) and insect pests of canola
TLDR
The findings confirm that C. sativa is unlikely to support high populations of these insect pests on the Canadian prairies and contains antibiosis factors against bertha armyworm.Abstract:
In an investigation of Camelina sativa (Linnaeus) Crantz (Brassicaceae) and five common insect pests of canola (Brassica napus Linnaeus) (Brassicaceae), little feeding damage to the plant was inflicted by crucifer-feeding specialist flea beetles (Phyllotreta Chevrolat species) (Coleoptera: Chrysomelidae), Delia Robineau-Desvoidy (Diptera: Anthomyiidae) root maggots, or diamondback moth (Plutella xylostella Linnaeus (Lepidoptera: Plutellidae)). In choice tests, diamondback moths laid fewer eggs on C. sativa than on B. napus leaves. Diamondback moth larvae consumed less C. sativa leaf tissue, and tended to have a longer developmental period on C. sativa. Larvae of the polyphagous bertha armyworm (Mamestra configurata Walker (Lepidoptera: Noctuidae)) had similar feeding levels on C. sativa and B. napus plants. However, there was a longer developmental period from larval to pupal stage and pupae weighed less when fed on C. sativa foliage, suggesting that C. sativa contains antibiosis factors against bertha armyworm. Two strains of aster yellows phytoplasma, 16SrI-A and 16SrI-B, were identified in C. sativa and in Macrosteles quadrilineatus (Forbes) (Hemiptera: Cicadellidae). Differences in incidence of aster yellows and abundance of M. quadrilineatus were observed among lines of C. sativa. The findings confirm that C. sativa is unlikely to support high populations of these insect pests on the Canadian prairies.read more

Camelina uses, genetics, genomics, production, and management
TL;DR: Although the breadth of research in camelina over the last few years is impressive, several areas that would benefit from further research were identified and compiled and summarized new and existing information in order to identify gaps in knowledge and areas for future research.

Inoculation of Soil with Plant Growth Promoting Bacteria Producing 1-Aminocyclopropane-1-Carboxylate Deaminase or Expression of the Corresponding acdS Gene in Transgenic Plants Increases Salinity Tolerance in Camelina sativa

TL;DR: The potential benefit of using either PGPB that produce ACC deaminase or transgenic plants expressing the acdS gene under the control of a root-specific promoter to facilitate plant growth, seed production and seed quality on land that is not normally suitable for the majority of crops due to high salt content is demonstrated.

Metabolism of the plant hormone jasmonate: a sentinel for tissue damage and master regulator of stress response
TL;DR: In this paper, the lipid-derived signal jasmonate (JA) orchestrates many of these inducible defense responses, including production of insect poisons, deterrents, and other anti-nutritive compounds.

Gene Expression Patterns in Roots of Camelina sativa With Enhanced Salinity Tolerance Arising From Inoculation of Soil With Plant Growth Promoting Bacteria Producing 1-Aminocyclopropane-1-Carboxylate Deaminase or Expression the Corresponding acdS Gene.
TL;DR: The study determined that several mechanisms appear to be responsible for the increased salinity tolerance and that the effect of acdS on gene expression patterns in C. sativa roots during salt stress is a function of how it is delivered.
