Estimates of genetic variances and relationship among traits associated with stem borer resistance in maize (Zea mays L.) by Oloyede-Kamiyo, Q., Ajala, S., Akoroda, M.O.

“…However, most of the landraces carrying the monogenic resistance are morphologically very similarand come from a geographically restricted area of West Africa, raising the possibility that the diversityof the single-gene resistance could be very limited, or even located at a single locus. …”

Textural classification of soils in rice-growing areas in Colombia by Silva, Mayesse Aparecida da, Rodríguez, Maryory, Majin, Marvin, Chirinda, Ngonidzashe

“…The soil units were differentiated by land shapes using a STRM 90-m DEM, and stratified by geopedological units from the Agustín Codazzi Geographic Institute (IGAC). The digital maps of soil texture were generated using the fuzzy logic approach, which enabled determining statistically the value limits of percent-slope classes, moisture index and standardized height on each of the soil units. …”

Biocontrol of the Major Plant Pathogen Ralstonia solanacearum in Irrigation Water and Host Plants by Novel Waterborne Lytic Bacteriophages by Álvarez, Belén, López, María M., Biosca, Elena G.

“…In this work, three lytic phages were isolated from environmental water from geographically distant regions in Spain. They proved to specifically infect a collection of R. solanacearum strains, and some of the closely related pathogenic species Ralstonia pseudosolanacearum, without affecting non-target environmental bacteria, and were able to lyze the pathogen populations within a wide range of conditions comprising environmental values of water temperatures, pH, salinity, and lack of aeration found in storage tanks. …”
