This cucumber grower is an excellent photographer. The photographs present a clear picture of the problem. Especially on the first photograph the chlorosis (yellowing) and downward curling of the leaves ( drooped leaves) are clearly visible. These are symptoms that are typical of cucumber mosaic virus strain C (CMV-C). This virus not only affects cucumber, but also other cucurbits like watermelon, squash etc. ; expressing the same symptoms as shown in the photographs presented by this grower.
A possible solution to the problem is to grow transgenic cucumbers , that are genetically modified to express the coat protein gene of CMV-C and therefore exhibits resistance to CMV.
More information about this solution can be found in the following publications :
1. "Transgenic melon and Squash expressing coat protein genes of aphid-borne viruses do not assist the spread of an aphid non-transmissible strain of cucumber mosaic virus in the field"
The authors are Marc Fuchs, Ferdinand E. Klas , James R. Mc Ferson and Dennis Gonsalves. Published in Transgenic Research 7, 449 - 462 ( 1998).
2. "Cantaloupe line CZW-30 containing coat protein genes of cucumber mosaic virus, zucchini mosaic virus and watermelon mosaic virus -2 is resistant to these three viruses in the field"
Published by Marc Fuchs et al. in Molcular Breeding 3: 279 - 290 (1997).
3. "Evaluation of transgenic tomatoes expressing the coat protein gene of cucumber mosaic virus strain WL under field conditions"
Authors : Marc Fuchs , Rosario Provvidenti, J.L Slightom and Dennis Gonsalves.
