The closer analysis of the narrow leaf phenotypes suggested a role in cell polarity of leaf cells, such that the length of individual cells was increased and the width reduced [ 15, 20].
The promoter activity of Hd3a was detected in transgenic plants expressing β-glucuronidase (GUS) under the control of the Hd3a promoter in the vascular cells of leaf blades.
The localization of TaSUT2 transcripts in the mesophyll cells of leaf blade might imply their significance in regulating intracellular sucrose partitioning within these cells of a leaf tissue.
The cells of leaf pieces treated with 3 mM HCl solution died 4.02 ± 1.02 h following treatment.
GL2 is normally expressed in developing trichomes and surrounding epidermal cells of leaf primordia, but is also detected in the petiole and mid-vein of developing leaves.
We investigated patterns of expression of cDNA for green fluorescent protein (GFP) under the control of the FIL promoter (the cDNA was designated FILp GFP), which is expressed in abaxial cells of leaf primordia (Watanabe and Okada, 2003).
Recently it has been shown that simultaneous depletion of myosins XI-1, XI-2 and XI-K caused defects in organization of actin filaments in root hairs and in the cells of leaf midvein epidermis [ 22].
In this study, we found that the xylem and phloem cells of leaf are more in drought-tolerant cultivar than in drought-susceptible cultivar after dehydration treatment; this might have resulted from the upregulation of Class III HD-ZIP gene.
On the other hand, another study demonstrated that at least one Class II gene (i.e., AtTPS6) involved in the regulation of cell shape and plant architecture was able to rescue the yeast Tsp1 mutant phenotype, suggesting that "AtTPS6 gene may be unique among class II AtTPS genes in affecting the cell shape of leaf pavement cells" [37].
The epidermal cell shapes of leaf blade in transverse section of A. variabilis show long and narrow shapes and its leaf margins are acute, which is different from the other morpho-types.
