Stomatal morphological parameters were:
guard cell length (Ls, um),
guard cell pair width (Ws, um), aperture length (La, um) andaperture width (Wa, um).
The mean lengths ([micro]m) of
guard cells at the upper epidermis were 1.51 [+ or -] 0.92, 1.72 [+ or -] 0.15 and 1.62 [+ or -] 0.84 at Oluku, Agbor and sapele roads respectively while at the lower epidermis, the
guard cell lengths were 1.85 [+ or -] 0.40, 1.12 [+ or -] 0.64 and 1.71 [+ or -] 0.46, respectively.
Guard cells: At ventral surface no significant changes have been observed in
guard cell lengths during winter months.
Designed to be useful to both industrial and academic researchers, the 14 papers here cover receptor kinases and their ligands, heterotrimeric G-protein-coupled signaling in higher plants, ROP/RAC GTPases, mitogen-activated protein kinase cascades, calcium signals (their regulation, paradigms and networks), reactive oxygen signaling, lipid-mediated signaling, plant actin-binding and microtubule-binding proteins, PCI complexes and the ubiquitin proteasome system in development, signaling between the organelles and the nucleus, signaling by protein phosphorylation in cell division,
guard cell signaling and molecular networks of abiotic stress signaling.
The electrochemical cells were a postcolumn
guard cell and analytical cell containing dual electrodes in series.
The main characteristics noted in this paper include the epidermal cell shape and arrangement, and the stoma and
guard cell shape and arrangement.
The multisensory
guard cell, stomatal responses to blue light and abscisic acid.
Moreover NO has been identified as a mediator of
guard cell ABA signalling.
After HPLC separation, detection of SAM and SAH was accomplished using a model 5200A Coulochem II electrochemical detector (ESA) equipped with a dual analytical cell (model 5010) and a
guard cell (model 5020).
Under drought condition, ABA is synthesized in plant tissue and sent to the
guard cell as a stress signal.
