Bauer, S., T. Hymowitz, and G. R. Noel. 2007. Soybean cyst nematode resistance derived from Glycine tomentella in amphiploid (G. max x G. tomentella) hybrid lines. Nematropica 37:277-285. Soybean cyst nematode, Heterodera glycines, is an important yield l... see more

Objectives: Evaluate the association between rifampicin resistance and the presence of at least one SNP in the rpoB and ponA1 genes and the spoligotype defined lineages. Material and Methods: This study analyzed two databases of 484 genomes of M. tubercul... see more

The number of resistance genes in PI 89772 and PI 209332 conferring resistance to H. glycines race 3 is not well defined. Crosses of PI 89772 × 'Lee 68', PI 88788 × PI 89772, and 'Lee 68' × PI 209332 were made in the field and greenhouse. Several F1 and F... see more

The effect of increasing initial population density levels (Pi) of Meloidogyne incognita race 2 on nematode population development and yield of a susceptible (Prima2000) and resistant (LS5995) soybean cultivar was investigated. Two experiments, one in a h... see more

The Brazilian cowpea crop has been increasing in recent years due to the launch of new cultivars. However these are, in some cases, susceptible to cowpea aphid. In view of this, studies of the biology of, one of the main insect pests on advanced cowpea li... see more

Introduction: The jaguar (Panthera onca) is an apex carnivore that is vulnerable to habitat fragmentation, and some of its populations are believed to be isolated in México where it is classed as endangered. The main the objective of our study was to eval... see more

Background: In developing countries, the most common cause of neonatal mortality is neonatal sepsis. Currently, the most significant and common hospital acquired pathogen is Escherichia coli, associated with many problems such as septicemia, pneumonia and... see more

When studying the collection of spring soft wheat of different genetic origin, individual samples that are resistant to pathogens and can be used as sources of resistance to pathogens in their hybridization with winter varieties were selected.The source o... see more
