Abstract. The arms race between parasitic sequences and their hosts is a major driving force for evolution of gene control systems. Since transposable elements (TEs) are potentially deleterious, eukaryotes silence them by epigenetic mechanisms such as DNA methylation. Little is known about how TEs counteract silencing to propagate during evolution. Here, we report behavior of sequence-specific anti-silencing proteins used by Arabidopsis TEs and evolution of those proteins and their target sequences. We show that VANC, a TE-encoded anti-silencing protein, induces extensive DNA methylation loss throughout TEs. Related VANC proteins have evolved to hypomethylate TEs of completely different spectra. Targets for VANC proteins often form tandem re.

Organically farmed food has a bigger climate impact than conventionally farmed food, due to the greater areas of land required. This is the finding of a new international study involving Chalmers University of Technology, Sweden, published in the journal Nature . The researchers developed a new method for assessing the climate impact from land-use, and used this, along with other methods, to compare organic and conventional food production. The results show that organic food can result in much greater emissions. "Our study shows that organic peas, farmed in Sweden, have around a 50 percent bigger climate impact than conventionally farmed peas. For some foodstuffs, there is an even bigger difference -- for example, with organic Swedish winte.

New study shows that gene transfer from bacteria to algae allowed early life to move from water to land By Katie Willis on November 14, 2019 (University of Alberta Press release.). A new species of algae called Spirogloea muscicola was also discovered in the course of conducting this research. Image courtesy of Barbara and Michael Melkonian. Natural genetic engineering allowed plants to move from water to land, according to a new study by an international group of scientists from Canada, China, France, Germany, and Russia. “This is one of the most important events in the evolution of life on this planet—without which we as a species would not exist,” said, co-investigator and professor in the and at the University of Alberta. “The movement o.

Understated and important:the final part of the article discussion. Summary. African swine fever virus (ASFV) is a highly infectious disease of domestic pigs, with virulent isolates causing a rapidly fatal hemorrhagic fever. In contrast, the porcine species endogenous to Africa tolerate infection. The ability of the virus to persist in one host while killing another genetically related host implies that disease severity may be, in part, modulated by host genetic variation. To complement transcription profiling approaches to identify the underlying genetic variation in the host response to ASFV, we have taken a candidate gene approach based on known signaling pathways that interact with the virus-encoded immunomodulatory protein A238L. We rep.

POLICY AND PRACTICE REVIEWS ARTICLE. To maintain self-sufficiency in rice production and national food security, the Chinese government strongly supports research that aims at increasing the productivity of rice cultivation. Rice with genetic material from Bacillus thuringiensis (Bt rice) is transgenic rice that can reduce lepidopteran pest damage and the use of insecticides. It was developed in the 1990s and earned biosafety certificates in 2009. However, because of political reasons, its commercialization in China has been postponed, and, to date, Bt rice is not grown in China. We assess the opportunity cost of postponement of Bt rice commercialization in China between the years 2009 and 2019 and consider the external costs of pesticide us.

The International Food Policy Research Institute (IFPRI), BARI, and the Bangladesh Department of Agricultural Extension (DAE), with support from USAID, have now completed an independent impact evaluation, , to determine the impacts of Bt brinjal on pest infestation, pesticide use, crop yields, costs, revenues, and self-reported health outcomes. The study shows exciting results of how Bt brinjal can lead to real improvements in the lives of farmers. Bt brinjal leads to a:. 95 percent reduction in FSB infestation. 56 percent reduction in the environmental toxicity of pesticides used. 10 percent reduction in self-reported symptoms associated with pesticide exposure among individuals in households growing Bt brinjal. 42 percent increase in yields. $

, and , According to its , unpasteurised or “raw” milk can “heal the gut”, boost the immune system, prevent allergies, give you healthier skin and even contribute to bodybuilding. Perhaps more common is the idea that pasteurisation – the heating process used to kill harmful bacteria in milk – reduces the amount of vitamins and “good” bacteria in the drink, so raw milk is supposedly better for you. Recent suggest this perception is creating a growing demand for raw milk that some farmers are happily responding to. So what does the scientific evidence say? There’s some data to indicate pasteurisation can have a small effect on milk’s nutritional content. But drinking raw milk comes with the risk of contracting serious and potentially lethal i.

Reposted from Cornell Alliance for Science (Joan Conrow). Though much of the controversy around genetically modified crops is driven by the belief that the process of moving genes from one species to another is "unnatural," new research shows some 1 in 20 flowering plants are naturally transgenic. Dozens of plants, including bananas, peanuts, Surinam cherries, hops, cranberries and tea, contain the Agrobacterium microbe — the very same bacterium that scientists typically use to create GM crops.

From ETH News Website By: ETH researchers are involved in the development and implementation of a method to efficiently breed for disease-resistant beans in different regions of the world. Their work will help to improve the livelihood and food security of smallholders in developing countries. A genetic selection method helps African breeders to grow beans that are disease-resistant. (Photograph: Georgina Smith / CIAT / CC BY-NC-SA 2.0) For many people in Africa and Latin America, beans are an important staple. Historically described as “the meat of the poor”, beans are rich in protein and minerals, affordable and suitably filling. That is why they are served daily, often with several meals. In many regions, however, plant diseases severely.

Open access. Abstract Transposable elements (TEs) are mobile DNA sequences that colonize genomes and threaten genome integrity. As a result, several mechanisms appear to have emerged during eukaryotic evolution to suppress TE activity. However, TEs are ubiquitous and account for a prominent fraction of most eukaryotic genomes. We argue that the evolutionary success of TEs cannot be explained solely by evasion from host control mechanisms. Rather, some TEs have evolved commensal and even mutualistic strategies that mitigate the cost of their propagation. These coevolutionary processes promote the emergence of complex cellular activities, which in turn pave the way for cooption of TE sequences for organismal function. Authors , and Department.

Hijacking Egg formation. Highlights •Retrotransposons rarely mobilize in germline stem cells •Rather, a group of retrotransposons hijacks oogenesis to selectively target oocytes •The vast majority of transposons do not transpose even without piRNA protection •Neither abundance nor localization of transposon RNAs faithfully reflects mobility Summary Although animals have evolved multiple mechanisms to suppress transposons, "leaky" mobilizations that cause mutations and diseases still occur.

Open Access. Rice landraces tolerant of up to 2 weeks of complete submergence were collected from farmers’ fields in the 1950s. Success in fine mapping of SUBMERGENCE 1 (SUB1), a robust quantitative trait locus from the submergence tolerant FR13A landrace, has enabled marker-assisted breeding of high-yielding rice capable of enduring transient complete submergence. At the molecular level, SUB1 is a variable polygenic locus encoding two or three ethylene responsive factor (ERF) DNA binding proteins. All Oryza sativa accessions encode SUB1B and SUB1C at this locus. An additional ERF, SUB1A, is present at SUB1 in FR13A and other tolerant accessions. The induction of SUB1A expression by ethylene during submergence disrupts the elongation escape

Key finding:. In conclusion, we report that HI-Edit enables widespread application of genome-editing technologies for crop improvement. Compared with existing methods, HI-Edit is faster and more effective at delivering edits to advanced breeding materials, thereby avoiding the delay and high cost of introgression. Importantly, HI-Edit offers a path to transgene-free edited inbred lines, a major consideration for regulatory approval of genome-edited crops. We used HI-Edit to enable genome editing of monocots (maize and wheat) and dicots (Arabidopsis) by both maternal and paternal HI mechanisms. The MATL knockout system could be extended to rice and other mono-cots, and CENH3 and wide-crossing HI-Edit systems may be used in both monocots and d.
