IITA was recently granted a permit to carry out confined field trials (CFT) on genetically modified cassava (AMY3 RNAi transgenic lines). This research, carried out in collaboration with ETHZ Plant Biotechnology Lab in Zurich, aims to reduce starch breakdown in storage roots of cassava after pruning the shoots, prior to harvest of the crop. The objective is to obtain storage roots with lower postharvest physiological degradation without any loss of the nutritious starch.

Cassava (Manihot esculenta Crantz) is an important starchy food crop in sub-Saharan Africa as well as other tropical and subtropical regions. However, one of the challenges faced by cassava farmers is the high level of postharvest loss caused by rapid deterioration of the starch-rich roots which occurs naturally after harvesting. Although postharvest deterioration can be reduced by pruning the shoots of cassava plants without unearthing the roots, this poses a problem as the desirable starch stored in the root can be degraded by the plant after pruning, which in turn lowers the harvest yield and root quality.

To address this, a research project was conceived at ETH Zurich where cassava plants using cultivar 60444 were generated using RNAi as the tool to reduce starch breakdown in the root after pruning of the shoots. Extensive testing was carried out in greenhouses in Switzerland, where the plants were grown for three consecutive years.

“Our greenhouse experiments were an important first step, but they cannot substitute for genuine field conditions,” said Prof Samuel C. Zeema of ETH Zurich. “Hence, it is necessary to grow the plants in a tropical climate such as that of Nigeria. IITA is an excellently equipped and well-staffed institute at which to perform such a confined field trial.”

The CFT permit was issued by the National Biosafety Management Agency in accordance with the National Biosafety Agency Act 2015 and is for the period 22 September 2017 to 31 December 2018. IITA adheres strictly to national and international biosafety standards and will ensure that these are enforced during the trials, which will be carried out within the IITA campus in Ibadan.

The research is a fact-gathering process to gain fundamental knowledge about starch metabolism in the storage root and about cassava as a crop. The cassava plants from the confined field trial are not destined for the market nor for commercial development and therefore will not be consumed. And according to national regulations, all plants will be destroyed within the CFT site after analysis.

As part of the experiment, regrowth of stem cuttings from the plants will also be assessed, since regrowth may also depend on starch stored in the stem. This is important since cassava is normally propagated by stem cuttings and not by seed.

The primary beneficiaries of the knowledge gained from this research (and its eventual application for cassava improvement) would be cassava farmers in Nigeria and other regions.

  39. Greetings! This is my first visit to your blog! We are a team of volunteers and starting a new initiative in a community in the same niche. Your blog provided us beneficial information to work on. You have done a extraordinary job!

  40. The fact that so many online casinos chop and change their welcome bonuses complicates attempts to find a ВЈ5 no deposit bonus casino. Right now, free cash bonuses are rarer than ever. You were more likely to find a free ВЈ5 no deposit casino UK 2020 bonus, or a free ВЈ5 no deposit casino UK 2019 bonus than you are now. Going back further still, the probability a free ВЈ5 no deposit casino UK 2018 bonus was higher still. Finding a ВЈ5 no deposit bonus in 2021 is difficult. But it is possible. Nowadays most casinos automatically add bonuses, including free spins no deposit, so you often don’t need to use any bonus codes to claim them. However, some sites do still use these, which we will explain more about below. If you did not receive the no deposit free spins on sign up, make sure to contact customer support and request them. However, some of the free spins above are exclusives that we’ve managed to negotiate directly with the casinos themselves. In these cases you need to visit the casino using our link to activate them. https://www.goldenretrievers.es/foro/profile/barbracansler30/ No deposit casino free spins is the second most popular choice because it gives you a number of game rounds for free. These free game rounds are typically tied to a specific slot title or casino game that the casino want to promote. This website is using a security service to protect itself from online attacks.

The casino is among the very top mobile casinos, too, with a dedicated iPad iPhone and Android casino so that you can play all the games available on any device. The games on offer cover everything: every table game, scratch cards, and so on. It has games for all major game providers, so you get to play Microgaming slots, Playtech slots, and many others.

  41. You are so cool! I do not suppose I’ve read a single thing like that before. So nice to find somebody with a few unique thoughts on this subject. Really.. many thanks for starting this up. This web site is one thing that is needed on the web, someone with a little originality.

We hebben het web afgezocht naar veilige online casino minimum desposit die over de betalingsmethoden en -systemen beschikken waarmee je voor slechts 1 euro deposit kunt spelen. The no deposit bonus works in a 1 euro deposit casino exactly the same as in any other online casino that you come across on CasinoScout.nl. Even though some players are uncomfortable with online banking, in Netherlands, there has been an increase in online casinos with 1 euro (iDeal) minimum deposits. IDeal is a great option for players who require fast and secure deposits. A casino for Europe is an online casino, which, as one of the options for refilling the account, withdrawing winnings and making stakes, is used. These institutions are rarely called “European casinos”, since they are rarely targeted by players from the countries of Europe. Most of these establishments provide users with not only a pleasant pastime, but also a multilingual support service to maximize the satisfaction of those who play from more than 20 countries, where the euro is the main currency.
