Abstract. Various features of the biology rust fungi and epidemiology plant diseases they cause illustrate important role rainfall in their life history. Based on this insight we have characterized ice nucleation activity (INA) aerially disseminated spores (urediospores) group fungi. Urediospores obligate parasite were collected from natural infections 7 species weeds France, coffee Brazil field greenhouse-grown wheat USA, Turkey Syria. Immersion freezing was used to determine onset...
ABSTRACT The partial nucleotide sequence of the coat protein (CP) gene Ethiopian isolates chickpea chlorotic stunt virus (CpCSV, genus Polerovirus ), beet western yellows (BWYV, and soybean dwarf (SbDV, Luteovirus ) was determined from lentil plants showing yellowing, stunting, reddening symptoms. Comparative analysis CpCSV obtained five showed 94.9%–100% 91.9%–98.7% identity with each other reference isolates, respectively. One isolate (MZ043728) a close relationship serotype II while...
typical of virus infection (chlorosis, stunting, necrosis, yellowing, and reddening) were collected during disease
Alfalfa leaf curl virus (ALCV), which causes severe disease symptoms in alfalfa (Medicago sativa L.) and is transmitted by the widespread aphid species, Aphis craccivora Koch, has been found throughout Mediterranean basin as well Iran Argentina. Here we reconstruct evolutionary history of ALCV attempt to determine whether recent discovery detection attributable either past diagnostic biases or emergence global spread over few years. One hundred twenty complete genome sequences recovered from...
In Sudan yellowing viruses are key production constraints in pulse crops. Field surveys were carried out to identify luteovirids affecting chickpea crops the major regions (Gezira Scheme and River Nile State). A total of 415 plant samples with stunting symptoms collected during 2013, 2015 2018 growing seasons. Serological results (Tissue-blot immunoassays) showed that Luteoviridae Chickpea chlorotic dwarf virus (CpCDV, genus Mastrevirus, family Geminiviridae) most common viruses, rare...
Abstract Food legumes are key commodities produced in sole and mixed cropping system Ethiopia. Their productivity has been affected recently by virus infections. Field surveys were conducted from 2018/19 to 2021/22 seasons the highlands of Ethiopia identify major viruses determine how biophysical factors affect disease incidence. A total 2797 samples chickpea (755), lentil (1683), fenugreek (111) grass pea (248) collected 194 farmers' fields Amhara (North Shewa, South Wollo East Gojjam...
Abstract. In light of various features the biology rust fungi and epidemiology plant diseases they cause that illustrate important role rainfall in their life history, we have characterized ice nucleation activity (INA) aerially disseminated spores (urediospores) this group fungi. Urediospores obligate parasite were collected from natural infections 7 species weeds France, coffee Brazil field greenhouse-grown wheat USA, Turkey Syria. Immersion freezing was used to determine onset...
Abstract Germplasm exchange from international genebanks and breeding programs is vital for successful crop improvement programs. More than 10,000 different accessions of wheat, barley, lentil, faba bean, chickpea, grasspea, pasture forage crops are distributed by the International Center Agricultural Research in Dry Areas (ICARDA) every year to around 70 countries. New added germplasm collections Center's genebank utilized Recent years have witnessed an increasing global concern about loss...
As water resources become more and scarce, production of crops under dry land conditions brings agriculture into potential conflict with other uses water. There is an emerging awareness that the orientation goals plant breeding can be shifted to create offset negative impacts on environment in order make sustainable. Here we have explored possibility select lines wheat, crop occupies than any individual crop, contribute bioprecipitation cycle. In this cycle ice nucleation (IN) active...
