“…14.1) is among the latest new industrial oilseed crops being developed by improving native germplasm for commercial cultivation in the United States. Interest in Lesquerella species for domestication came in the late 1950s and subsequent research and commercialization efforts are viewed as a model for new crop species [6,7]. The beginning of lesquerella as a new crop started with the national oilseeds screening program of over 200 plant families growing in native habitats initiated by the New Crops Research Branch of the US Department of Agriculture (USDA), Agricultural Research Service (ARS) [8,9].…”

Lesquerella (Physaria fendleri) is a new oilseed crop that is being domesticated as an alternative crop for arid regions in the United States. As a member of the Brassica family, the species exhibits a high seed-oil content that can provide a source of hydroxy fatty acids for industrial use as source of bioenergy and by-products that can be utilized in livestock production. Germplasm evaluation and breeding activities on the crop have been done by the University of Arizona and the US Department of Agriculture (USDA). Lesquerella and other Physaria and Paysonia species have a substantial germplasm collection that is well characterized for phenotypic traits and oil profiles. There are several improved germplasm released by the USDA with higher oil content and seed yield, enhanced oil profile, abiotic stress tolerance, and harvest index which can be directly utilized for commercial production or used for crop improvement. Additional technologies that can aid breeding, such as molecular marker systems and genetic transformation systems, have been established. A few challenges remain to be surmounted for the crop to be commercialized. A continued concerted effort by public and private institutions may hasten the process of bringing this new crop to commercial production.

Lesquerella, Physaria fendleri (A. Gray) S. Watson, is a mustard native to the western United States and is currently being developed as a commercial source of valuable hydroxy fatty acids that can be used in a number of industrial applications, including biolubricants, biofuel additives, motor oils, resins, waxes, nylons, plastics, corrosion inhibitors, cosmetics, and coatings. The plant is cultivated as a winter-spring annual and in the desert southwest it harbors large populations of arthropods, several of which could be significant pests once production expands. Lygus spp. (Hemiptera: Miridae) are common in lesquerella and are known pests of a number of agronomic and horticultural crops where they feed primarily on reproductive tissues. A 4-yr replicated plot study was undertaken to evaluate the probable impact of Lygus spp. on production of this potential new crop. Plant damage and subsequent seed yield and quality were examined relative to variable and representative densities of Lygus spp. (0.3-4.9 insects per sweep net) resulting from variable frequency and timing of insecticide applications. Increasing damage to various fruiting structures (flowers [0.9-13.9%], buds [1.2-7.1%], and seed pods [19.4-42.5%]) was significantly associated with increasing pest abundance, particularly the abundance of nymphs, in all years. This damage, however, did not consistently translate into reductions in seed yield (481-1,336 kg/ha), individual seed weight (0.5-0.7 g per 1,000 seed), or seed oil content (21.8-30.4%), and pest abundance generally explained relatively little of the variation in crop yield and quality. Negative effects on yield were not sensitive to the timing of pest damage (early versus late season) but were more pronounced during years when potential yields were lower due to weed competition and other agronomic factors. Results suggest that if the crop is established and managed in a more optimal fashion, Lygus spp. may not significantly limit yield. Nonetheless, additional work will be needed once more uniform cultivars become available and yield effects can be more precisely measured. Densities of Lygus spp. in unsprayed lesquerella are on par with those in other known agroecosystem level sources of this pest (e.g., forage and seed alfalfa, Medicago sativa L.). Thus, lesquerella production may introduce new challenges to pest management in crops such as cotton.

Current progress towards the metabolic engineering of plant seed oil for hydroxy fatty acids production

2015

Hydroxy fatty acids produced in plant seed oil are important industrial material. This review focuses on the use of metabolic engineering approaches for the production of hydroxy fatty acids in transgenic plants. Vegetable oil is not only edible but can also be used for industrial purposes. The industrial demand for vegetable oil will increase with the continued depletion of fossil fuels and ensuing environmental issues such as climate change, caused by increased carbon dioxide in the air. Some plants accumulate high levels of unusual fatty acids in their seeds, and these fatty acids (FAs) have properties that make them suitable for industrial applications. Hydroxy fatty acids (HFAs) are some of the most important of these industrial FAs. Castor oil is the conventional source of HFA. However, due to the presence of toxin ricin in its seeds, castor is not cultivated on a large scale. Lesquerella is another HFA accumulator and is currently being developed as a new crop for a safe source of HFAs. The mechanisms of HFA synthesis and accumulation have been extensively studied using castor genes and the model plant Arabidopsis. HFAs accumulated to 17% in the seed oil of Arabidopsis expressing a FA hydroxylase gene from castor (RcFAH12), but its seed oil content and plant growth decreased. When RcFAH12 gene was coexpressed with additional castor gene(s) in Arabidopsis, ~30% HFAs were accumulated and the seed oil content and plant growth was almost restored to the wild-type level. Further advancement of our understanding of pathways, genes and regulatory mechanisms underlying synthesis and accumulation of HFAs is essential to developing and implementing effective genetic approaches for enhancing HFA production in oilseeds.
