“…Vicia faba nectaries are described by Davis et al (1988) and illustrated in Davis and Gunning (1992 (Gates et al, 1983; though see Stoddard, 1993) (Kato, 1988 (Harder and Barrett, 1996;Snow et al, 1996) and increased levels of self-pollination, particularly geitonogamy (Handel, 1983;Barrett, 1995, 1996). Pollen flow per flower can sometimes, therefore, be reduced by increasing floral display (Harder and Barrett, 1995).…”

“…Nectaries in Arabidopsis are at the base of stamen filaments, although the placement of nectaries varies across species (Figure 2) (Bowman and Smyth, 1999;Baum et al, 2001;Pillitteri et al, 2008;Kram et al, 2009). Modified stomata are generally larger than epidermal stomata and more often found in contact with one another (Figure 2) (Davis and Gunning, 1993). In addition, hydathode and nectaries cannot regulate pore aperture, leaving modified stomata continually open.…”

Stomata consist of two guard cells that function as turgor-operated valves that regulate gas exchange in plants. In Arabidopsis, a dedicated cell lineage is initiated and undergoes a series of cell divisions and cell-state transitions to produce a stoma. A set of basic helix-loop-helix (bHLH) transcription factors regulates the transition and differentiation events through the lineage, while the placement of stomata relative to each other is controlled by intercellular signaling via peptide ligands, transmembrane receptors, and mitogen-activated protein kinase (MAPK) modules. Some genes involved in regulating stomatal differentiation or density are also involved in hormonal and environmental stress responses, which may provide a link between modulation of stomatal development or function in response to changes in the environment. Premitotic polarlylocalized proteins provide an added layer of regulation, which can be addressed more thoroughly with the identification of additional proteins in this pathway. Linking the networks that control stomatal development promises to bring advances to our understanding of signal transduction, cell polarity, and cell-fate specification in plants.

“…The terms 'modified stomata' (Fahn, 1979; Davis and Gunning, 1992) are used here to represent the pore structures of Eucalyptus nectaries. They share specific developmental features (eg, breakthrough; Carr and Carr, 1987) and likeness with foliar stomata, but evidently are unable to close their pores by guard-cell movements (Davis, 1969).…”

Summary — Floral nectaries and their production of major nectar carbohydrates were studied in three species of Eucalyptus in Australia. In E cosmophylla, E grandis and E pulverulenta, the nectary is located on the inner surface of the hypanthium, below the stamen filaments. Nectary surfaces possessed hundreds of modified stomata that were solitary, distributed uniformly, asynchronous in development, and served as exits for nectar flow. Nectar yields per bagged flower were greatest in E cosmophylla and least in E grandis, correlating with flower size but not nectary stomatal density. The nectar of E pulverulenta was sucrose-rich, but hexose-rich for the others. Few changes in nectar carbohydrate composition were detected between flowers whether protected or continually exposed to visitors (eg, honeybees), and whether young or old, indicating an overall constancy in composition for the long period of nectar availability.Eucalyptus / honeybee / modified stomata / nectar carbohydrate / nectary surface
