Total RNAs were extracted from leaf samples of zucchini plants inoculated with either inoculation buffer (mock) or cell sap
of pSA1164 or pVD2EDIII infected plants (2nd passage).
Under normal temperature condition (0 d), no differences in ion concentrations of cell sap
were found between drought-preconditioned and nonpreconditioned plants (Table 1).
With a pH-sensitive micro-electrode setup, the scientists found that the pigment cell sap
increases in pH during this process, converting from acidic to basic, and driving the color transformation.
An increase in ion concentration in leaf cell sap
could cause retardation of enzymatic activities and processes (Naeem et al.
The heavy infestation causes leaves to yellow and gradually dry.Mealybugs are soft-bodied wingless insects that feed by inserting their long stylets into the plants drawing the cell sap
