Lipids Online 2022 : the role of elongase 2 on EPA and DHA metabolism (free webinar)

Details
Published on 11 July 2022

“The role of elongase 2 on eicosapentaenoic acid and docosahexaenoic acid metabolism” is the title of the coming ISSFAL’s seminar. This free webinar will be proposed the 13th of July 2022 (10:00 AM New York City | 15:00 London | 10:00 PM Singapore) by Adam Metherel, PhD (Department of Nutritional Sciences @University of Toronto, Canada https://nutrisci.med.utoronto.ca/faculty/adam-metherel).

Increases in eicosapentaenoic acid (EPA, 20:5n-3) levels following docosahexaenoic acid (DHA, 22:6n-3) supplementation has long been explained by the retroconversion pathway. Conversely, a lack of increase in DHA levels following precursor supplementation, such as EPA, has been used as evidence for low DHA synthesis rates. However, recent evidence from animal and human modeling reveals that increases in EPA with DHA supplementation may be the result of an inhibition of EPA metabolism, and despite no changes in DHA levels with EPA supplementation, substantial synthesis of DHA occurs. New evidence indicates that inhibition of elongase 2 by DHA may explain the increased EPA levels – not retroconversion. Elongase 2 also appears to be an important regulatory enzyme for DHA synthesis, particularly as a mechanism to explain the well-known higher DHA levels in women compared with men. This presentation will review these findings and present new evidence highlighting the potentially important role of elongase 2 in EPA and DHA metabolism.

LOOKING BACK - Origin of Male Sterilities and Sunflower Hybrid Varieties in France and Worldwide

Details
Published on 21 April 2022

by: Bernard VIVIER,  INRAE – Agri-Obtentions, Clermont-Ferrand, France (retired)

"The edible oil most widely used in France before 1970 was obtained from imported groundnuts. During the 1960s, the French government decided to develop oil crops that could be produced in France, to replace these importations. INRAE was asked to undertake research programmes concerning rapeseed and sunflower. The latter species was not grown in France at this time, except for small areas in South-Eastern France, mainly for bird feed (mostly the variety Gris Strié de Provence) and in gardens during World War 2, to provide a small amount of oil. In the 1960s, the sunflower crop was most important in the USSR, mainly in southern Russia and Ukraine, using open pollinated varieties bred for their high oil contents by V. PUSTOVOIT at Krasnodar.

Discovery of Genic Male Sterility

Simone LENOBLE, who was in charge of the sunflower programme at INRAE, Clermont-Ferrand, contacted the VNIIMK at Krasnodar to obtain samples of their different varieties. Collaborations were implemented with the French Association of oil seed multipliers (USGOS/AMSOL) and the CETIOM (now Terres Inovia), the technical institute, to multiply, test and distribute this material. In 1962, the first samples were grown in the INRAE sunflower nursery, and one plant producing no pollen was observed, it was male sterile. Such plants are very rare and its observation was the equivalent of some medical discoveries.

This male sterile plant showed no particular coloration (it was described as “green”). An old French variety, “Nain Noir”, present in the 1962 sunflower nursery, showed red coloration on stems, petioles and leaf edges, due to the presence of anthocyanins (defined as “red”). Pollen from this variety was applied on the male sterile plant. The seeds obtained were sown in the greenhouse in October 1962. At emergence, all the seedlings showed the red coloration. This character was therefore considered to show dominant inheritance.

In February 1963, I joined the sunflower laboratory at INRAE, Clermont-Ferrand. With S. Lenoble, when the plants in the greenhouse flowered, we observed that they all produced pollen (they were male fertile). They were self-pollinated, by covering the heads with bags. The seed harvested was sown in spring 1963 and at flowering, the ¾ plants, which were all “red”, were all male fertile whereas the ¼ plants which were “green” were all male sterile. The two characters followed the laws of Mendel for major genes and were very closely linked genetically. This was the discovery of what is known as genic male sterility in sunflower, marked by the presence or absence of red coloration (Leclercq, 1966). However, since the male sterile character shows recessive inheritance, it was not possible to obtain a progeny with 100% male sterile plants. To permit crossing with another line to produce uniform hybrids, it was necessary to remove all the “red” plants before flowering. Lines developed from various Russian and Bulgarian varieties were used as male parents to pollinate the male sterile plants. To permit research and breeding on a larger scale, the sunflower team was enlarged with the arrival of two technicians.

Development of the First Hybrid Variety

Field trials to compare the yield and oil content of the experimental hybrids led to the registration in 1970 on the French Official Catalogue of the first sunflower hybrid in the world, INRA 6501. In the same period, a very early open pollinated variety, ISSANKA, was registered by INRAE at Montpellier.

Large scale cropping of sunflower in France started in about 1968 using the open pollinated varieties imported from the USSR by USGOS/AMSOL and recommended after study by CETIOM/Terres Inovia. Production of INRA 6501 and field trials of other hybrids were developed by collaboration between INRAE and seeds firms in areas of France with climates adapted to sunflower: Limagne, Rhone valley, western and southwestern France.

Pollination of sunflowers is mainly carried out by bees, which can collect pollen and nectar quite far from their hives. Large scale hybrid seed productions and checks of the uniformity of the seed produced made it possible to determine the distance, about one kilometre, necessary to isolate hybrid production from other sunflower crops.

Multiplication of the female parent required the seed to be sown very densely before removal of all the « red » plants in the bands designated « female », from which the seed was harvested and all the « green plants » in the bands designated « male » which produced the pollen. This required a large amount of manual labour as was also the case for the female parent in commercial hybrid production.

Discovery of Cytoplasmic Male Sterility

At the same time as the commercial development of « genic hybrids », under the direction of André CAUDERON, Patrice LECLERQ, who succeeded Simone LENOBLE (who transferred to Lusignan to work on forage crops), made some interspecific crosses in the nursey, between cultivated sunflower (Helianthus annuus) and related wild species, samples of which were provided by the American scientist C. HEISER. 

From a cross between the wild species Helianthus petiolaris and H. annuus, he obtained plants with a cytoplasmic male sterility (a character determined in the cytoplasm, under maternal inheritance). Published by Leclercq (1969), this male sterility gives progenies with 100% of the plants producing no pollen, and thus largely simplifying hybrid seed production. The male parents of cytoplasmic hybrids must carry restorer genes, which were obtained from several Helianthus species (Kinman, 1970, Leclercq, 1971). The first cytoplasmic hybrid in the world, registered in France in 1973 was called RELAX to indicate the simplicity of its production.

This cytoplasmic male sterility, distributed with no limitation or patent is still used freely and almost exclusively used throughout the world and has been the basis of an enormous extension of the sunflower crop in very many countries (Vear 2010). This development was also helped by pioneer research in sunflower agronomy and mechanisation.

 Conclusion

These discoveries of male sterilities in sunflower made it possible to obtain hybrid varieties showing much more uniform height and maturity dates, compared with the old open-pollinated varieties, simplifying agronomic procedures. They also made possible more rapid progress in breeding for characters such as disease resistance and oil quality which can be rapidly fixed in parental lines (Vear 2016). They were the basis of the many breeding programmes developed in Europe, North America, South America and, more recently Asia.

The sunflower crop should continue to have a good future as it requires few   inputs other than seed, is quite drought resistant and produces several sorts of edible oil much appreciated by consumers."

OCL Journal: Quick Feedback

Details
Published on 02 March 2022

As you know, OCL journal is a not-for-profit, peer-reviewed, full Open-Access scientific journal devoted to fats, lipids and oil- and protein-crops.

OCL covers the entire sector. The research papers and reviews published address a range of topical matters in agronomy, plant biology, biochemistry, analytical chemistry, lipid chemistry, as well as transversal research themes such as nutrition, the health-quality-food safety nexus, innovation and industrial processes, the environment and sustainable development, economics and social development.

In 2013, the decision was taken to relaunch the French journal OCL as an international publication: its title was therefore anglicized to OCL-Oilseeds and fats, Crops and Lipids. Today, we have achieved the goals we set for ourselves in 2013:

  • the proportion of articles published in English has been rising steadily, to reach 100% in 2021;
  • the strict peer-review policy to ensure high-standard articles has been enhanced (in 2021, only slightly more than 40% of the articles submitted were accepted);
  • OCL metrics have been increasing steadily, reaching the 2nd quartile in 2017 (agronomy section) and getting now very close from Q1 according to the Scopus Index.

In order to help us to improve our service, we would be thankful if you could take a few minutes to answer the following questions.
