New study identifies genetic basis for western corn rootworm resistance in maize

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Farmers are stuck. Western corn rootworm can destroy cornfields — and profits — but populations of the “billion-dollar bug” have stopped responding to insecticides and the genetically modified corn hybrids designed to resist insect attacks. But there may be hope. In a new study, University of Illinois researchers uncover the genetic basis of resistance to western corn rootworm, paving the way for development of non-GM corn hybrids that can withstand the worm.“Our previous research showed that there is no inherent resistance in the elite hybrids grown by most farmers in the Midwest,” said Martin Bohn, corn breeder in the Department of Crop Sciences at U of I. “We want to improve native resistance to western corn rootworm in maize, without using transgenics.”The work was done within the context of a large, longstanding project called Germplasm Enhancement of Maize (GEM), which aims to diversify the tools available to corn breeders by tapping the genetic resources of maize accessions from all over the world.“Some of my colleagues look into lines that yield more, some look into nutritional characteristics. We were screening for insect resistance. There were not that many, but we found some. We had to look into lines from Argentina, Brazil, and the Caribbean Islands to find it,” Bohn said.The resistant corn lines can’t just be released here in the United States. For one thing, the plants are massive, leggy giants compared to the elite hybrids Midwestern farmers are used to growing. They’re also adapted to very different environments, and wouldn’t flower at the right time to produce reasonable yields.By crossing exotic and elite lines, GEM created plants with a quarter of the genes of the exotics. Several of these lines remained promising with regard to their level of resistance.But the team still didn’t know why the new lines were resistant.“What is the genetic basis of resistance? If you find that, then you can screen other exotic materials for resistance much more efficiently and effectively, with a more targeted approach,” Bohn said.The researchers haven’t found the gene for resistance — Bohn says the trait is likely too complex for it to boil down to a single gene — but the group has identified regions of the genome that appear to contribute to resistance, using a technique known as QTL mapping. There were some common themes among the regions.“When we look at other genes in these regions, one of the common denominators is ascorbate biosynthesis,” Bohn said.In other words, one mechanism explaining western corn rootworm resistance might be the manufacture of ascorbate in the plant. The ascorbate synthesis pathway produces free radicals that injure feeding insects.The analysis turned up another set of genes that may be involved in resistance, but this one is a little more complex. When western corn rootworm larvae are feeding on roots, some corn plants release a compound into the soil that calls nematodes to attack the larvae. The second set of genes appears to be related to the manufacture of compounds that attract those nematodes.“This is very important because plants can’t uproot themselves and go somewhere else, so they have to use other mechanisms to protect themselves,” Bohn said.The results are a first step in introducing native resistance mechanisms into new elite hybrids, but much more research is needed before that happens. And Bohn cautions that the level of native resistance found in the study is no match for the power of transgenic insect-resistant corn, at least not yet.“The idea is when you know where the genes with these small effects are located, perhaps it is possible to bring them into one common genetic background. If we can accumulate these genes, over time we might increase the level of resistance so that it makes sense for farmers to grow them.”The article, “Quantitative trait loci mapping of western corn rootworm (Coleoptera: Chrysomelidae) host plant resistance in two populations of doubled haploid lines in maize (Zea mays L.),” is published in the Journal of Economic Entomology. Bohn’s co-authors include J. Marroquin from U of I, S. Flint-Garcia and B. Hibbard from USDA-ARS, K. Dashiell from the International Institute of Tropical Agriculture in Nigeria, and D. Willmot from AgReliant Genetics.The work was partially supported by funds from the USDA-ARS “Germplasm Enhancement in 477 Maize” Project by Specific Cooperative Agreements and the Hatch Project ILLU-802-315.last_img read more

Lopetegui set for awkward encounter with Ronaldo Messi is the best

House Passes Cybercrimes Act

first_imgFacebook Twitter Google+LinkedInPinterestWhatsApp Facebook Twitter Google+LinkedInPinterestWhatsAppKINGSTON, Oct. 14 (JIS): The Cybercrimes Act, which seeks to address computer specific offences, was passed in the House of Representatives on Tuesday (October 13) with two amendments.The new Act will replace the 2010 legislation, and incorporates new offences such as computer-related fraud or forgery; the use of computers for malicious communication; and unauthorised disclosure of investigation.It also addresses the use of the computer for malicious communication.Minister of State in the Ministry of Science, Technology, Energy and Mining, Hon. Julian Robinson, informed that the clause was included “because there is a new phenomenon called cyberbulling.”“This is where persons wilfully send messages, which are designed to annoy, and harass. The data that is sent must be obscene or is menacing in nature. The person sending the data does so intending to cause or is reckless as to whether the sending of the data causes annoyance, inconvenience or distress,” he explained.Opposition Spokesperson on Information Communications Technology (ICT), Dr. Andrew Wheately, while welcoming the provision to address cyberbulling, said the clause could have the effect of inhibiting use of information communications technology (ICT). “This section has the most far-reaching implications of this Act. The intention of this section is to no doubt reduce the incidence of cyberbullying, which we fully endorse. However, it seems to be completely oblivious to the level of sophistication of the layman technology user,” he said.I am sure that members on both sides of this House will agree that this section cannot stand as is. It cannot be that a person who…. makes a mistake while sending an email, text message or other correspondence could be charged with a crime,” he argued further.Mr. Robinson, in acknowledging the concerns, said Clause 9 Section 1 (b) is to be amended to state that a person commits an offence, if that person wilfully uses a computer to send to another person any data that is obscene or offensive.“I want to assure persons, who may send a message and they think that simply sending a message, which might be a joke, that you will be caught here. That is not what this provision is meant to deal with,” Mr. Robinson said. In closing the debate, Minister of Science, Technology, Energy and Mining,Hon. Phillip Paulwell, noted that offences under the Bill require an act and intent.“We have been faithful to ensure that both aspects are provided for, so no innocent bystander will be caught by this. Nobody, who is engaged in doing ICT business, will be caught by this, as you must have intent to do some wrong and the onus is to establish that the intent has been proven,” Mr. Paulwell said.The legislation will now be sent to the Senate for its approval.

Pindling envisioned that one day the College of The Bahamas would become the University of The Bahamas (UB), a dream realized with UB’s charter on 10th November 2016. At its historic inaugural Commencement held on 25th May 2017, the University posthumously conferred upon Sir Lynden its first honorary degree.Acting on behalf of UB trustees, upon the recommendation of faculty, UB President Dr. Rodney D. Smith (left) and Board of Trustees Chair Dr. Earl Cash (right) presented the degree, Doctor of the University Honoris Causa, to Sir Lynden’s daughter, Ms. Monique Pindling. The inaugural Commencement was held at the Thomas A. Robinson Stadium.According to the citation, Sir Lynden deserved the honour because he served the country with distinction as Prime Minister; he became the Father of the Nation and under his leadership sovereignty for The Bahamas came to fruition 10th July 1973; and as a significant part of his vision for a better Bahamas and its citizens, he spearheaded the establishment of COB which has transitioned to UB.UB also scored a record number of graduates this year, with 790 persons. Last year, 594 students graduated from what was then the College of The Bahamas.#magneticmedianews#UBfirsthonorarydegreelast_img read more
