The symptom and genetic diversity of cassava brown streak viruses infecting cassava in East Africa [PDF]
, 2012 The genetic and symptom diversity of six virus isolates causing cassava brown streak disease (CBSD) in the endemic (Kenya, Mozambique, and Tanzania) and the recently affected epidemic areas (Uganda) of eastern Africa was studied.

Turfgrass species response exposed to increasing rates of glyphosate application [PDF]
, 2009 To investigate the response of nine turfgrass species exposed to increasing rates of glyphosate application, the dry matter production, visual leaf injury symptoms (e.g., chlorosis and necrosis) and the concentrations of shikimate and mineral nutrients ...

The Global Influence of Sodium on Cyanobacteria in Resuscitation from Nitrogen Starvation
Biology, 2023 Dormancy and resuscitation are key to bacterial survival under fluctuating environmental conditions. In the absence of combined nitrogen sources, the non-diazotrophic model cyanobacterium Synechocystis sp.

Photosystem Perturbation by Staygreen Mutations Confers Allele-Dependent Defences Against Infections of Pathogens With Different Lifestyles and Abiotic Stress Tolerance. [PDF]
Plant Cell EnvironABSTRACT The staygreen (SGR) gene encodes the magnesium dechelatase that plays an important regulatory role during chlorophyll degradation. Our previous work revealed a nonsynonymous SNP (A323G) inside cucumber CsSGR that is responsible for multiple disease resistance (MDR), but the underlying mechanism is unknown.

The use of attenuated isolates of Pepino mosaic virus for cross-protection [PDF]
, 2010 Pepino mosaic virus (PepMV) has recently emerged as a highly infectious viral pathogen in tomato crops. Greenhouse trials were conducted under conditions similar to commercial tomato production.
