Abstract
Tomato yellow leaf curl virus (TYLCV) was characterized as a whitefly‐transmitted monopartite Geminivirus. The viral genome DNA fragment of 1.1 kb was successfully amplified from infected tissues using polymerase chain reaction (PCR) technology. Chemical constituents of infected tomato leave tissues were severely influenced. Photosynthetic pigments, chlorophyll a and b, total lipids, saturated and unsaturated fatty acids, sugar and protein contents were significantly decreased compared with healthy tissues of test plants. On the other hand, total phenols accumulated to a greater extent in infected leaves. The concentrations of ascorbic acid, as an antioxidant, leaf extract pH were not dramatically affected by the virus. The extent of increase or decrease of such constituents was varied based on the plant developmental stages at the time of infection. It was concluded from this study that some of the biochemical constituents in tomato leaves were changed in response to TYLCV infection.
