The Cellulose synthase superfamily synthesizes cellulose and different hemicellulosic polysaccharides in plant cell walls. While much has been discovered about the evolution and function of these genes, their genomic architecture and relationship with gene (sub-)functionalization and evolution remains unclear. By using 242 genomes covering plant ev...

Translational genomics can enable a quicker improvement of orphan crops toward novel agricultural applications, including the advancement of orphan biomass species for cultivation on marginal lands. In this sense, cell wall quality is a preeminent breeding target. However, tools to efficiently project genetic data on target traits across large sets...

The Plantarray 3.0 phenotyping platform ® was used to monitor the growth and water use of the quinoa varieties Pasto and selRiobamba under salinity (0–300 mM NaCl). Salinity reduced the cumulative transpiration of both varieties by 60% at 200 mM NaCl and by 75 and 82% at 300 mM NaCl for selRiobamba and Pasto, respectively. Stomatal conductance was...

Hemp (Cannabis sativa L.) is a bast-fiber crop with a great potential in the emerging bio-based economy. Yet, hemp breeding for fiber quality is restricted and that is mainly due to the limited knowledge of the genetic architecture of its fiber quality. A panel of 123 hemp accessions, with large phenotypic variability, was used to study the genetic...

Quinoa is a nutritious seed crop with a great potential to grow in saline soils. Here, we studied ion concentrations in quinoa tissues throughout the life cycle of the plant, and linked ion dynamics to responses in growth parameters, seed yield and efficiency of photosynthesis under salinity (0 to 400 mM NaCl). Ion dynamics changed from high ion ex...

Increased soil salinity is a significant agricultural problem that decreases yields for common agricultural crops. Its dynamics require cost and labour effective measurement techniques and widely acknowledged methods are not present yet. We investigated the potential of Unmanned Aerial Vehicle (UAV) remote sensing to measure salt stress in quinoa p...

Crambe abyssinica (crambe) is a new industry oil crop that can grow on saline soil and tolerant salty water irrigation. Genetically engineered crambe in which the seed-oil composition is manipulated for more erucic acid and less polyunsaturated fatty acid (PUFA) would be highly beneficial to industry. In this research, lysophosphatidic acyltransfer...

Camelina (Camelina sativa L. Crantz) is considered a relatively new oilseed Brassicacea in both Europe and North America, even though its history as a crop dates back to the Bronze Age. Camelina has recently received renewed interest from both the scientific community and bio-based industries around the world. The main attractive features of this s...

Conference Paper
The on-going EU-funded project ‘COSMOS - Camelina & crambe Oil crops as Sources for Medium-chain Oils for Specialty oleochemicals’ aims to turn two underutilized crops, camelina and crambe, into profitable, sustainable, multipurpose, non-GMO European oil crops for the production of oleochemicals. These crops do not compete with food crops in terms...

Background Economical cultivation of the oilseed crop Jatropha curcas is currently hampered in part due to the non-availability of purpose-bred cultivars. Although genetic maps and genome sequence data exist for this crop, marker-assisted breeding has not yet been implemented due to a lack of available marker–trait association studies. To identify...

The T-DNA region of pMF1 vector of marker-free system developed by Wageningen UR, has Recombinase R-LBD gene fusion and nptII and codA gene fusion between two recombination sites. After transformation applying dexamethasone (DEX) can activate the recombinase to remove the T-DNA fragment between recombination sites. The recombinant ought to be selec...

Crambe abyssinica is a hexaploid oil crop for industrial applications. An increase of erucic acid (C22:1) and reduction of polyunsaturated fatty acid (PUFA) contents in crambe oil is a valuable improvement. An increase in oleic acid (C18:1), a reduction in PUFA and possibly an increase in C22:1 can be obtained by down-regulating the expression of f...
Article
Full-text available
Background Crambe abyssinica (crambe) is a non-food oil seed crop. Its seed oil is widely used in the chemical industry because of the high erucic acid content. Furthermore, it is a potential platform for various feedstock oils for industrial uses based on genetic modification. Here, we describe the development of a series of protocols for all step...

Background: The main bottleneck to elevate jatropha (Jatropha curcas L.) from a wild species to a profitable biodiesel crop is the low genetic and phenotypic variation found in different regions of the world, hampering efficient plant breeding for productivity traits. In this study, 182 accessions from Asia (91), Africa (35), South America (9) and...

Quinoa is immens populair. Dit van oorsprong Zuid-Amerikaanse voedselgewas is wereldwijd aan een opmars bezig. Mede dankzij Wageningse veredelaars is er nu ook quinoa uit Frankrijk, Engeland en Duitsland. En binnenkort misschien ook uit Nederland. ‘Dit wordt een beslissend jaar.’

Crambe abyssinica produces high erucic acid (C22:1, 55-60 %) in the seed oil, which can be further increased by reduction of polyunsaturated fatty acid (PUFA) levels. The omega-6 fatty acid desaturase enzyme (FAD2) is known to be involved in PUFA biosynthesis. In crambe, three CaFAD2 genes, CaFAD2-C1, CaFAD2-C2 and CaFAD2-C3 are expressed. The indi...

Crambe (Crambe abyssinica Hochst ex. R. E. Fries) is an ideal crop for industrial oil production because of its high erucic acid content (C22:1, approx. 60 %) in its seed oil. The value of crambe oil can be improved by increasing C22:1 content or reducing polyunsaturated fatty acids (PUFA). The FAD2 gene plays a critical role in PUFA biosynthesis....

Current efforts to grow the tropical oilseed crop Jatropha curcas L. economically are hampered by the lack of cultivars and the presence of toxic phorbol esters (PE) within the seeds of most provenances. These PE restrict the conversion of seed cake into animal feed, although naturally occurring 'nontoxic' provenances exist which produce seed lacki...

Erucic acid (22 : 1) is a major feedstock for the oleochemical industry. In this study, a gene stacking strategy was employed to develop transgenic Crambe abyssinica lines with increased 22 : 1 levels. Through integration of the LdLPAAT, BnFAE1 and CaFAD2-RNAi genes into the crambe genome, confirmed by Southern blot and qRT-PCR, the average levels...

We applied fifteen microsatellite markers for molecular identification of cocoa (Theobroma cacao L.) varieties and their beans in the production chain, and for distinguishing 'fine or flavour' cocoa from bulk varieties. Thirteen markers were from Lanaud et al. (1999) and listed in the International Cocoa Germplasm Database. All of these mTcCIR mark...

Jatropha curcas shows a big promise towards sustainable and affordable biofuels. Several groups are working independently towards development of both agrosystems and high quality germplasm of jatropha, and downstream processing and biodiesel markets. The challenges are to make the big promises come true: high oil yield, low competition with food cr...

The water footprint (WF) of energy crops should be calculated by relating the energy yield of a crop to its actual water use under actual climatic conditions during the growing season. Recently, average precipitation and additional irrigation to satisfy potential crop water requirements were used as input to the WF computation (1). We disagree with...
