ABSTRACT
Forty-one Mexican species of Eragrostis are compared anatomically. On the basis of the structure of the abaxial epidermis as seen in surface view and the inner structure as seen in cross section of the leaf blade, ten groups are recognized, one with three subgroups. Important differences were found in the presence of papillae; shape of the stomata, microhairs, and silica bodies; position of the vascular bundles; shape of the outer bundle sheath; presence of an adaxial extension of the outer bundle sheath; distribution of the costal abaxial and adaxial sclerenchyma; distribution of the intercostal abaxial sclerenchyma; distribution of the bulliform and colorless cells; and the arrangement and distribution of the chlorenchyma cells. Eragrostis obtusiflora and E. spicata are so distinctive among the species studied that their inclusion in Eragrostis is uncertain.

    Two highly specialized cells, the guard cells that surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture and thereby the gas exchange.

    HvHKT1 mediates K+ or Na+ uniport in yeast cells if the expression promoter is joined directly to the HvHKT1 cDNA, and Na+–K+ symport if a 59 nucleotide polylinker is inserted. Our results show that three ATG triplets in the polylinker decreased the synthesis of the transporter and that...

    Background and Aims Although orbicular functions are still a matter of debate, they are considered by most authors to be exclusively formed by a secretory tapetum. However, the presence of orbicules on a peritapetal membrane associated with a plasmodial tapetum has been described for Abutilon...
