The cotton blue disease, caused by the cotton leafroll dwarf virus (CLRDV), leads to dwarfism, leaf rolling, and production loss in susceptible cotton varieties. To develop an enzyme-linked immunosorbent assay (ELISA) test to detect the virus in cotton and weeds, peptides based on the coat protein were used to produce polyclonal (a-GQE, a-PRN, and a-INK) and monoclonal (a-GQE, a-PRN, and a-NKF) antibodies. All six were tested as capture antibodies, and polyclonal a-GQE and the monocle onal a-NKF were labeled with the enzyme alkaline phosphatase and used as detection antibodies for a double antibody sandwich (DAS) ELISA method, in which p-nitrophenyl phosphate was added and measured by absorbance at 405 nm. The DAS-ELISA sandwich was efficient in discriminating between healthy and diseased plant extracts. The ELISA methodology detected the virus in the weeds Commelina sp., which was confirmed by RT-PCR. The monoclonal antibodies may be used to develop other diagnostic procedures. |

Oil palm (Elaeis guineensis Jacq.) is an oilseed crop of great economic importance. The oil palm industry has a large-scale production worldwide and uses high efficient extraction and refining processes to obtain palm oil and palm kernel oil. In Brazil, currently, there is an extensive area suitable for oil palm planting outside the Amazon rainforest; however, these areas go through long periods of water scarcity and demand artificial irrigation to be sustainable. One-quarter of the irrigated area in agriculture has a problem with salinity stress. |
