Stomatal studies in Amaryllidaceae with special reference to stomatal abnormalities

Stomata in Close Contact: The Case of Pancratium maritimum L. (Amaryllidaceae)

“…The connection observed between the two stomata crosses the cytoplasm of the intervening pavement cell approximately in the middle of the distance between its periclinal cell walls (brackets in Figure 6 e). Though until now this connection has been characterized as “cytoplasmic,” [ 20 , 22 , 24 , 25 ], the findings of this study reveal that this connection does not consist of any membranous material (i.e., no staining with FM 4.64 or no effect on it when epidermal peels were subjected to a hypertonic solution) and should be considered as a cell wall strand. This cell wall strand contains fully and partially methylesterified homogalacturonans, homogalacturonans with low levels of methylesterification associated with each other by calcium bridges, and nonesterified homogalacturonans (LM20, LM18, 2F4, LM19 respectively).…”

“…Species of the genera Asparagus , Asphodelus , Allium of the Asparagaceae, Asphodelaceae and Amaryllidaceae families were examined. Also, a wider range of species was examined [ 24 ], though the focus was on the Amaryllidaceae family. The considered species were Agapanthus umbellatus, Allium cepa, Allium sativa, Allium tuberosum, Amaryllis belladonna, Amaryllis yittate, Nerine curvifolia, Crinum zeylanicum, Crinum asiatisum, Cyrtanthus mackenii, Zephyranthes candida, Cooperia pedunculata, Haemanthus multiflorus, Pancratium verecundum and Narcissus tazetta.…”

“…The principal works examining anatomy in the Amaryllidaceae were performed using several species from diverse countries of the world [ 22 , 23 , 24 ]. These authors report the internal structure of Amaryllidaceae species belonging to several species and genera.…”
