Abstract A mathematical model relating environmental temperatures to rest completion of 2 peach cultivars has been developed. The equates effective chill-units, such that, one can predict when will or completed with a high degree accuracy.
ABSTRACT The highly pathogenic (HP) influenza viruses H5 and H7 are usually nonpathogenic in mallard ducks. However, the currently circulating HP H5N1 acquired a different phenotype able to cause mortality mallards. To establish molecular basis of this phenotype, we cloned human A/Vietnam/1203/04 (H5N1) virus isolate that is ferrets, mice, mallards found it be heterogeneous mixture. Large-plaque isolates were ducks, whereas small-plaque these species. Sequence analysis entire genome revealed...
Abstract A model has been developed that relates the stages of spring bud development ‘Redhaven’ and ‘Elberta’ peaches ( Primus persica (L.) Batsch) to an accumulation growing degree hours following rest completion. The is based on a lower limit 4.5°C upper 25°.
Phytophthora stem and root rot, caused by sojae, is one of the most destructive diseases soybean [Glycine max (L.) Merr.], incidence this disease has been increasing in several soybean-producing areas around world. This presents serious limitations for production, with yield losses from 4 to 100%. The effective method reduce damage would be grow Phytophthora-resistant cultivars, two types host resistance have described. Race-specific conditioned single dominant Rps ("resistance sojae") genes...
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi Syd., is a widespread disease of [ Glycine max (L.) Merr.] with the potential to cause serious economic losses. The objective this study was genetically map red‐brown lesion type resistance from cultivar Hyuuga. A population 117 recombinant inbred lines (RILs) cross Dillon (tan lesion) × Hyuuga (red‐brown [RB] rated for ASR in field and inoculated P. greenhouse. RB gene mapped between Satt460 Satt307 on linkage group (LG)‐C2....
Abstract Human infection with avian influenza A(H9N2) virus was identified in Bangladesh 2011. Surveillance for viruses apparently healthy poultry live-bird markets during 2008–2011 showed that subtype H9N2 are isolated year-round, whereas highly pathogenic H5N1 co-isolated primarily the winter months. Phylogenetic analysis of they reassortants possessing 3 gene segments related to H7N3; remaining were from G1 clade. We detected no reassortment viruses. Serologic analyses chickens revealed...
The current dogma of influenza accepts that feral aquatic birds are the reservoir for A viruses. Although genomic information human viruses is increasing, little this type data available circulating in waterfowl. This study presents genetic characterization 35 isolated from wild Canadian ducks 1983 to 2000, as first attempt at a comprehensive genotypic analysis ducks. demonstrates virus genes have achieved evolutionary stasis. majority these duck clustered distinct North American clades;...
Avian influenza subtype H9N2 is endemic in many bird species Asia and the Middle East has contributed to genesis of H5N1, H7N9 H10N8, which are potential pandemic threats. viruses that have spread Bangladesh acquired multiple gene segments from highly pathogenic (HP) H7N3 presumably Pakistan currently cocirculate with HP H5N1. However, source geographic origin these not clear. We characterized complete genetic sequences 37 Bangladeshi isolated 2011-2013 investigated their inter-...
Soybean [ Glycine max (L.) Merr.] seed phosphorus is stored primarily as phytic acid, a form in which it unavailable to monogastric mammals and birds. Because of the nutritional environmental problems caused by development cultivars with low acid ( lpa ) mutations has become an important objective many soybean breeding programs. Information about inheritance phytate trait would facilitate these efforts. The objectives current research were (i) map loci populations derived from mutant line...
ABSTRACT Soybean [ Glycine max (L.) Merr.] resistance to soybean rust (SBR) caused by Phakopsora pachyrhizi could reduce reliance on fungicides manage this disease. The objective of study was identify germplasm with field populations P. in the United States. Field evaluations 576 accessions from USDA Germplasm Collection for SBR were conducted at seven locations southern States between 2006 and 2008. Accessions maturity groups (MG) 000 X North American susceptible check cultivars each MG...
Highly pathogenic H5N1 and low H9N2 influenza viruses are endemic to poultry markets in Bangladesh have cocirculated since 2008. circulated constantly the markets, whereas highly occurred sporadically, with peaks of activity cooler months. Thirty isolated from were characterized by antigenic, molecular, phylogenetic analyses. clades 2.2.2 2.3.2.1 live bird only. Phylogenetic analysis 30 isolates revealed multiple introductions Bangladesh. There was no reassortment between local genotype,...
In 2011, avian influenza surveillance at the Bangladesh live bird markets (LBMs) showed complete replacement of highly pathogenic (HPAI) H5N1 virus clade 2.2.2 (Qinghai-like lineage) by HPAI 2.3.2.1. This clade, which continues to circulate in and neighboring countries, is an intra-and interclade reassortant; its HA, polymerase basic 1 (PB1), (PA), nonstructural (NS) genes come from subclade 2.3.2.1a; 2 (PB2) comes 2.3.2.1c; NA, nucleocapsid protein (NP), matrix (M) gene 2.3.4.2. The H9N2...
A transgenic line of the soybean 'Jack', Glycine max (L.) Merrill, expressing a synthetic cry1Ac gene from Bacillus thuringiensis variety kurstaki (Jack-Bt), was evaluated for resistance to four lepidopteran pests in field. Jack-Bt and genotypes serving as susceptible resistant controls were planted field cages artificially infested with larvae corn earworm, Helicoverpa zea (Boddie), velvetbean caterpillar, Anticarsia gemmatalis (Hübner), 1996, 1997, 1998, also looper, Pseudoplusia includens...
There has been limited success over the past 30 yr in development of superior soybean cultivars [ Glycine max (L.) Merr] with insect resistance. Success may be hampered by quantitative nature resistance and linkage drag from resistant plant introduction (PI) donor parents. Soybean trait loci (SIR QTLs) have identified PI 229358 171451 restriction fragment length polymorphism (RFLP) analysis. The objective this study was to tag SIR QTLs simple sequence repeat (SSR) markers determine extent...
ABSTRACT Utilization of native insect resistance genes can be an important component for managing insects in soybean [ Glycine max (L.) Merr.]. A major quantitative trait locus (QTL‐M) from PI 229358, controlling antibiosis and antixenosis, was previously identified on linkage group (LG) M found to increase the effectiveness a Bacillus thuringiensis (Bt) transgene soybean. The objectives this study were fine‐map QTL‐M using recombinant substitution lines (RSLs) ‘Benning’ backcross...
