Diamond Debate | Hot 200m clash

first_imgAndre Lowe: They are building a nice little rivalry, and Saturday’s 200m clash between Elaine Thompson and Dafne Schippers should certainly be as exciting as their previous races against each other. KC Graham: I think this rivalry will be the best among female athletes for the next two years as both are kind of fresh on the scene and look likely to be the best over the event. Lowe: Well, their times certainly support that position. Those 21.66 and 21.63 runs by the two at last year’s World Championships are still fresh in the mind and certainly breathe fresh life into the event. Schippers has looked really good already this year – 7.00 in the 60m, 10.83 in the 100m and 22.02 after two 200m races. She has ran a lot this year, which is a discussion on its own. The point, though, is that this will be Thompson’s first 200m this season and maybe this will also come into play. KC Graham: Last year, Thompson was very inexperienced, plus she can also now commit some more time to her career after going pro. Now she will be more relaxed, and after her excellent debut on the world stage last year, I think she is ready to do some damage. Her coach, Stephen Francis, has worked on her start, and based on what I saw at the Jamaica International Invitational meet, she is going to do something special this year, and Eugene could be the start of this. Lowe: Her start has come a long way. It could hardly have been any worse, to be honest, and with this new weapon in her arsenal, she is now better equipped to beat the big Dutch sprinter. This one is going to be a hard call. I expect them to go very close to 22-flat here. I wouldn’t be surprised if they both scrape 21.9 highs. I’m inclined to give Dafne the edge for now, but I really can’t say that it’s a confident pick. KC Graham: Yes, Dafne has got the edge over Elaine the last two times they met, and with a season’s best of 22.02 seconds, which is a world-leading time in the event, the Dutch lady will start as favourite. Elaine is a monster and only lost because of inexperience in Beijing last year and is ready to avenge that defeat. I see both athletes going sub-22 seconds here. We cannot ignore Tori Bowie because, remember at this same track two years ago, she won the event running out of lane one in 22.18 seconds, and with a season’s best of 22.26 seconds in The Bahamas, she cannot be ignored. Lowe: Hmmm … Bowie could spoil the fun, for real. Since that run in Nassau, she has gone 10.80 and 10.91 in the 100m, so she is in good overall form. It’s her best start to a season in a while, and she’ll certainly complete the top three here. Where they each finish is the next question. I have my doubts, but I’ll go with Dafne, slightly over Elaine with Bowie pushing hard for third. KC Graham: I am going to make a bold prediction here, and people might say I am crazy. After her spectacular performance at the same track in 2014 and with her best start to a season, I am going with Bowie at home to surprise the big two here. Lowe: All things considered, it’s not that crazy. It’s a bolder prediction, but one that’s certainly possible. Either way, it’s not a race to be missed!last_img read more

How caterpillars use their feces to fool corn

first_imgFor some caterpillars, pooping where they eat is an unavoidable fact of life—even if it’s on the very corn they eat. Now, researchers report that keeping this excrement on hand may be part of the caterpillar’s master plan to dupe the plant into turning off its defenses, allowing the caterpillars to eat more and grow faster.For years, chemical ecologist Dawn Luthe and her students wondered why fall armyworm caterpillars (Spodoptera frugiperda) let piles of feces, known as frass, accumulate on corn, trapped in the plant’s cuplike whorls where the leaves join the stalk. The whorls “are a moist and enclosed space. And the frass, which can become rather liquidy, is right next to the open wounds left by the caterpillar chewing on the plant,” says Luthe of Pennsylvania State University, University Park. “It sounds unpleasant. But to us, it was an obvious question to ask what the effect … was.”In particular, the researchers were curious about what impact chemical cues in the feces were having on the corn. In recent years, scientists have identified a host of compounds called chemical elicitors—found, for example, in insect saliva—that can limit plant defenses, including the production of bad-tasting compounds that ward off herbivores.

Country Email In the new study, the researchers collected the caterpillar frass and turned it into an extract, which they applied to wounded corn leaves. They found that in leaf tissue treated with the fecal extract for 24 hours, the plant switched off its herbivore defense genes, but flipped on its pathogen defense genes, which inhibit the growth of pathogenic fungi or bacteria. In most plants, the two pathways can’t be turned on at the same time. That’s because a defense hormone called salicylic acid (SA), which controls the pathogen defense pathway, inhibits the production of another defense hormone—jasmonic acid (JA)—that controls the herbivore defense pathway.When Luthe and colleagues measured SA and JA levels in treated leaves, they discovered that JA dropped rapidly, whereas SA increased the longer the extract was applied. JA is produced immediately after something damages the plant tissue, and its accumulation usually leads to the creation of the compounds the insects find so distasteful. The production of SA, however, is typically delayed, explaining why leaves needed to be treated for 24 hours before an effect could be seen, the scientists say.When the researchers compared the caterpillars’ growth rates over 4 days, they found that caterpillars fed leaves that had been treated with the extract for 24 hours grew bigger faster than those that ate leaves treated for a shorter period of time, they report in the Journal of Chemical Ecology. And the scientists discovered that leaves treated with the fecal solution for 24 hours also had reduced growth of a fungus known to cause southern leaf blight disease in corn.The exact component of the frass that causes the switch in the plant’s defensive strategy remains a mystery. It could be a protein or group of proteins, Luthe says. In future studies, the researchers will try to nail down the mechanism, which could one day lead to the development of an organic fungicide, she says.Even though that’s possible, says chemical ecologist Andre Kessler of Cornell University, we’re still a long way from an actual application. “What’s most interesting is that the study has helped further establish that the plant can perceive the feces, and that it is not enough to just consider the effect insects have on plants through feeding. You’ve got to consider everything, even down to the poop.”center_img Country * Afghanistan Aland Islands Albania Algeria Andorra Angola Anguilla Antarctica Antigua and Barbuda Argentina Armenia Aruba Australia Austria Azerbaijan Bahamas Bahrain Bangladesh Barbados Belarus Belgium Belize Benin Bermuda Bhutan Bolivia, Plurinational State of Bonaire, Sint Eustatius and Saba Bosnia and Herzegovina Botswana Bouvet Island Brazil British Indian Ocean Territory Brunei Darussalam Bulgaria Burkina Faso Burundi Cambodia Cameroon Canada Cape Verde Cayman Islands Central African Republic Chad Chile China Christmas Island Cocos (Keeling) Islands Colombia Comoros Congo Congo, the Democratic Republic of the Cook Islands Costa Rica Cote d’Ivoire Croatia Cuba Curaçao Cyprus Czech Republic Denmark Djibouti Dominica Dominican Republic Ecuador Egypt El Salvador Equatorial Guinea Eritrea Estonia Ethiopia Falkland Islands (Malvinas) Faroe Islands Fiji Finland France French Guiana French Polynesia French Southern Territories Gabon Gambia Georgia Germany Ghana Gibraltar Greece Greenland Grenada Guadeloupe Guatemala Guernsey Guinea Guinea-Bissau Guyana Haiti Heard Island and McDonald Islands Holy See (Vatican City State) Honduras Hungary Iceland India Indonesia Iran, Islamic Republic of Iraq Ireland Isle of Man Israel Italy Jamaica Japan Jersey Jordan Kazakhstan Kenya Kiribati Korea, Democratic People’s Republic of Korea, Republic of Kuwait Kyrgyzstan Lao People’s Democratic Republic Latvia Lebanon Lesotho Liberia Libyan Arab Jamahiriya Liechtenstein Lithuania Luxembourg Macao Macedonia, the former Yugoslav Republic of Madagascar Malawi Malaysia Maldives Mali Malta Martinique Mauritania Mauritius Mayotte Mexico Moldova, Republic of Monaco Mongolia Montenegro Montserrat Morocco Mozambique Myanmar Namibia Nauru Nepal Netherlands New Caledonia New Zealand Nicaragua Niger Nigeria Niue Norfolk Island Norway Oman Pakistan Palestine Panama Papua New Guinea Paraguay Peru Philippines Pitcairn Poland Portugal Qatar Reunion Romania Russian Federation Rwanda Saint Barthélemy Saint Helena, Ascension and Tristan da Cunha Saint Kitts and Nevis Saint Lucia Saint Martin (French part) Saint Pierre and Miquelon Saint Vincent and the Grenadines Samoa San Marino Sao Tome and Principe Saudi Arabia Senegal Serbia Seychelles Sierra Leone Singapore Sint Maarten (Dutch part) Slovakia Slovenia Solomon Islands Somalia South Africa South Georgia and the South Sandwich Islands South Sudan Spain Sri Lanka Sudan Suriname Svalbard and Jan Mayen Swaziland Sweden Switzerland Syrian Arab Republic Taiwan Tajikistan Tanzania, United Republic of Thailand Timor-Leste Togo Tokelau Tonga Trinidad and Tobago Tunisia Turkey Turkmenistan Turks and Caicos Islands Tuvalu Uganda Ukraine United Arab Emirates United Kingdom United States Uruguay Uzbekistan Vanuatu Venezuela, Bolivarian Republic of Vietnam Virgin Islands, British Wallis and Futuna Western Sahara Yemen Zambia Zimbabwe Click to view the privacy policy.
