| a soluble fraction requirement in the transfer reaction of protein synthesis by rice embryo ribosomes. | the requirements for the transfer of (14)c-phenylalanine from yeast soluble ribonucleic acid to protein in vitro by rice (oryza sativa l. var. bluebonnet) ribosomes have been investigated. an absolute requirement for polyuridylic acid, 2-mercaptoethanol, guanosine triphosphate, magnesium, and potassium or ammonium ions and ribosomes has been demonstrated. ribosomes washed in 0.5% sodium deoxycholate also required the presence of rice supernatant. the optimum concentration of magnesium ion for th ... | 1966 | 16656417 |
| [micromorphology of leaf epidermis of some venezuelan rice cultivars (poaceae) associated with the mechanical damage of sogata t. orizicolus (homoptera: delphacidae)]. | rice cultivars are affected directly and indirectly by the insect sogata. the mechanical damage or direct loss, is produced after feeding and ovoposition on the young leaves tissues, while the indirect damage is produced after the transmission of the rice hoja blanca virus. we studied the morpho-anatomic structures associated with the resistance of the mechanical damage produced by the insect, in six rice cultivars, including controls for resistance and susceptibility (makalioka and bluebonnet 5 ... | 2014 | 25102661 |
| mechanisms of oryza sativa (poaceae) resistance to tagosodes orizicolus (homoptera: delphacidae) under greenhouse condition in venezuela. | tagosodes orizicolus is one of the main plagues of rice in tropical america causing two types of damages, the direct one, feeding and oviposition effect, and an indirect one, by the transmission of the "rice hoja blanca virus". during 2006-2007 we carried out research under greenhouse conditions at fundaci6n danac, venezuela, in order to determine the mechanisms of antixenosis, antibiosis and tolerance to t. orizicolus, which could be acting in commercial varieties and advanced lines of the rice ... | 2012 | 22458212 |
| yellow feet in a patient with breast and thyroid carcinoma, due to oral intake of turmeric. | yellow discoloration of the skin may be caused by several etiologies, including jaundice, hypervitaminosis, drug reaction or chemical exposure. herein we describe a 68-year-old woman with a history of breast and thyroid carcinoma, presenting with a yellow discoloration of her soles, after ingestion of one capsule a day of turmeric root extract (bluebonnet turmeric root, 500 mg, vcap), taken for its anti-cancer properties, for 4 months. after drug cessation, the yellow hue disappeared completely. ... | 2015 | 27747716 |
| flavonoids from lupinus texensis and their free radical scavenging activity. | seventeen flavonoids including one new compound were isolated from texas bluebonnet (lupinus texensis), the state flower of texas. their structures were determined by extensive nuclear magnetic resonance and high-resolution electrospray ionization mass spectrometry analyses. high-performance liquid chromatography analytic method for simultaneous determination of the 17 compounds was established and validated. eleven isolated flavonoids were first evaluated for their free radical scavenging activ ... | 2011 | 21707249 |
| a pentamer-repeat-containing dna sequence in texas bluebonnet (lupinus texensis hook.) | a 654-bp ecori restriction fragment called lup4 was shotgun cloned from texas bluebonnet (lupinus texensis hook.) nuclear genomic dna that had been extracted from plant leaves. its sequence was determined on both strands. southern blot analysis of ecori-digested texas bluebonnet dna revealed clone hybridization throughout the approximately 1.0 to > 23 kb size range; the darkest hybridization was in the high molecular weight range (approximately 6 to > 23 kb). using dot blot analysis, the copy nu ... | 1998 | 9796104 |
| an arginyl-transfer ribonucleic acid protein transferase from cereal embryos. | embryos from rice (oryza sativa l. var. bluebonnet) and wheat (triticum aestivum l.) contain an aminoacyl-trna protein transferase which transfers arginine from arginyl-trna to the n terminus of a protein acceptor. the activity was measured in vitro in a reaction mixture containing embryo supernatant fraction, buffer, sulfhydryl reagent, and arginyl-trna. it was not dependent on the usual cofactors for ribosomal protein synthesis, nor was it sensitive to cycloheximide or puromycin. however, the ... | 1973 | 16658490 |
| metabolism of 3',4'-dichloropropionanilide: 3,4-dichloroaniline-lignin complex in rice plants. | rice plants (oryza sativa l. var. bluebonnet 50) metabolize the herbicide 3',4'-dichloropropionanilide to 3,4-dichloroaniline, which in turn conjugates with carbohydrates. soluble aniline-carbohydrate complexes account for only a small fraction of the hydrolyzed 3',4'-dichloropropionanilide. the major portion of the 3,4-dichloroaniline moiety is found complexed with polymeric cell constituents, mainly lignin. the aniline is lignin-bound as 3,4-dichloroaniline and not as 3',4'-dichloropropionanil ... | 1968 | 5661296 |
| homogenization of populations in the wildflower, texas bluebonnet (lupinus texensis). | wildflower seeds are routinely spread along highways and thoroughfares throughout north america as part of federal beautification policy, but the genetic effect of the introduction of these cultivated populations on wild populations of the same species is unknown. interbreeding may occur between these seeded and wild populations, resulting in several possible outcomes. here we sample 187 individuals in 12 matched pairs of neighboring wild and seeded populations of the texas bluebonnet (lupinus t ... | 2018 | 29240932 |
| first report of bean yellow mosaic virus from diseased lupinus luteus in eastern washington. | lupine accessions from the cool season food legume seed collection are grown for seed regenerations in pullman, wa by the agricultural research service, western regional plant introduction station. selected seed was germinated in the greenhouse and assayed by indirect elisa using antiserum for potyvirus group detection (agdia, inc., elkhart, in). healthy transplants were grown for seed collection on outside plots. in july of 2005, more than 90% of 307 lupinus luteus l. transplants developed seve ... | 2009 | 30764209 |
| alternaria alternata causing flower stem blight of lupinus havardii. | lupinus havardii wats., commonly known as big bend or chisos bluebonnet, is a showy winter annual that can reach 1.0 to 1.5 m in height and produces blue, fragrant inflorescence (racemes). l. havardii is native to a narrow geographic range along the mexican border in southwest texas. the inflorescence of l. havardii has considerable potential in the cut flower industry where there is a need for high-quality, durable flowers with a blue color (1). several crops have been produced in the greenhous ... | 2001 | 30831959 |
| first report of ovulariopsis on lupinus havardii. | in 1998 and 1999 a severe powdery mildew was observed in las cruces, nm, on big bend bluebonnets (lupinus havardii) grown in the greenhouse for cut flowers and vase life studies. an undescribed powdery mildew has been reported on l. havardii (2), but it has been observed only occasionally on leaves and has not cause a severe problem. the powdery mildew observed in las cruces began in march and caused severe infection from may through july. the disease spread rapidly due to movement of the pathog ... | 2000 | 30841176 |
| first report of pythium paroecandrum on lupinus havardii. | lupinus havardii wats. (big bend bluebonnet), a plant native to texas, has been tested extensively for greenhouse production as a cutflower crop (1). disease symptoms were observed on l. havardii plants grown in las cruces, nm, during two consecutive years. plants were grown in metro mix 200 and watered by an automatic irrigation system every 3 days. during the growing season, which extended from september through february, 6% of mature plants (10-week-old plants) became chlorotic, wilted, and d ... | 1999 | 30841065 |
