stunt and Squash leaf curl begomoviruses-New threats to cucurbit crops in the Middle East.
Compared to the chlorotic
area, the chlorosis rate eliminates the influence of leaf size and more accurately reveals the process of leaf chlorosis.
Tobacco yellow dwarf virus (TbYDV) from Australia and Chickpea chlorotic
dwarf virus (CpCDV) from northern Africa and the Indian subcontinent were being isolated from dicots i.e., tobacco and chickpea respectively (Morris et al., 1992; Horn et al., 1993).

Typical symptoms include chlorotic
line patterns, ringspots, and mottles in leaves.
coli O157:H7 may team up with the downy mildew pathogen, which invades leaf cells when plants are wet, breaking down the leaf tissue and eventually creating chlorotic
(yellowing) and necrotic, dead spots.

The percentage of chlorotic
donor plants was low for both the nutrient treatment (4.5%) and the shade + nutrient treatment (0%).
Typical symptoms of septoria leaf blotch appeared as chlorotic
spots with the presence of small black dots that are pycnidia.
As symptoms progress, leaves become increasingly chlorotic
(yellow due to insufficient chlorophyll production) and necrotic (as cells die), and affected leaves often drop early from the plant.
The treatments used in this experiment were: (7) BArg; (2) BT9; (3) BT9 +chlorotic; (4) BT9 + chlorotic
+ stunt; and (5) BT9 + Brown.
