According to Taiz & Zeiger (2017), as the stress becomes more severe, the dehydration of mesophyll cells inhibits photosynthesis, thus damaging the metabolism and consequently hampering carboxylation efficiency.
Disturbance of phloem transport in Mg-deficient spruce needles could be also attributed to an increased sucrose gradient from the mesophyll toward the central cylinder in yellowing needles.

In addition to cuticle thickness, the parameter that significantly differed between the populations was SI of both the leaf sides; the height of the midrib, which was positively correlated with the thickness of the outer periclinal external walls of the adaxial surface of the leaf (r = 0.8357, p = 0.38); the number of ducts in the ground parenchyma of the midrib, which was positively correlated with the midrib width (r = 0.6482, p = 0.164) and the leaf area (r = 0.5573, p = 0.251); and the thickness of the mesophyll. The leaf area, which did not differ between the populations, was negatively correlated with the SI of the abaxial surface (r = -0.8699, p = 0.24).
Similarly, the sclerenchyma girders bordering the palisade mesophyll would reduce water loss from the palisade mesophyll as well as reduce heating of this tissue under high sunlight.
Hyperhydric leaves have vacuolated mesophyll cells with large intercellular spaces filled with water instead of air.
Particles releasing luciferin and coenzyme A were designed to accumulate in the extracellular space of the mesophyll, an inner layer of the leaf, while the smaller particles carrying luciferase enter the cells that make up the mesophyll.
In the infected leaves the fluorescently labeled TGBp3 was predominantly localized at the outer chloroplast membrane of mesophyll cells.
With regard to organization of the leaf chlorenchyma, isobilateral, centric, or dorsiventral mesophyll has occasionally been reported in Lamiaceae family [16].
