“…Our results for mature adult maize leaf wax composition are in broad agreement with an earlier study (Bianchi et al, 1984) and show considerable differences from juvenile leaves of maize (e.g., Bianchi et al, 1978) and barley (Richardson et al, 2005), where waxes are dominated by fatty alcohols, with low proportions of aldehydes, alkanes, and esters (Bianchi et al, 1978). Moreover, since previously published scanning EM images reveal no epicuticular wax crystals on the adult leaf surface (e.g., Sylvester & Smith, 2009), we conclude that the epicuticular wax layer we observed via TEM consists of an amorphous film without crystalline structure. While waxes (particularly fatty alcohols and wax esters) are predominantly intracuticular before and during establishment of the water barrier (4-7 and 8-11 cm from the leaf base), at later stages almost all extractable waxes are epicuticular.…”

“…The maize leaf develops from tip to base in a continuous gradient, providing an excellent system for comparative analysis of different developmental stages in a single leaf at one time point (Sylvester & Smith, 2009). For this study, we chose leaf 8, the first fully adult leaf, in a partially expanded state (50-60cm long) of the inbred line B73 as the standard for all experiments.…”

Running Title: Adult maize leaf cuticle developmentHiglight statement: Chemical, ultrastructural and functional analysis of cuticle development in partially expanded adult maize leaves revealed important roles for wax esters and an osmiophilic, likely cutin-rich, layer in protection from dehydration. AbstractAlthough extensive prior work has characterized cuticle composition, function, ultrastructure and development in many plant species, much remains to be learned about how these features are interrelated. Moreover, very little is known about the adult maize leaf cuticle in spite of its significance for agronomically important traits in this major crop. We analyzed cuticle composition, ultrastructure, and permeability along the developmental gradient of partially expanded adult maize leaves to probe the relationships between these features. The water barrier property is acquired at the cessation of cell expansion. Wax types and chain lengths accumulate asynchronously along the developmental gradient, while overall wax load does not vary. Cutin begins to accumulate prior to establishment of the water barrier and continues thereafter. Ultrastructurally, pavement cell cuticles consist of an epicuticular layer, a thin cuticle proper that acquires an inner, osmiophilic layer during development, and no cuticular layer. Cuticular waxes of the adult maize leaf are dominated by alkanes and wax esters localized mainly in the epicuticular layer. Establishment of the water barrier coincides with a switch from alkanes to esters as the major wax type, and the emergence of an osmiophilic (likely cutin-rich) layer of the cuticle proper.

“…Accordingly, the growing leaf is thought to be organized in the distal maturation, central expansion and proximal division zones (Fournier et al ). In the division zone, cells undergo both longitudinal and transverse divisions to support growth in leaf width and length, respectively (Sylvester and Smith ) (Figure E). Final leaf size and shape result from spatial and temporal coordination of these processes.…”

In cereals, tillering and leaf development are key factors in the concept of crop ideotype, introduced in the 1960s to enhance crop yield, via manipulation of plant architecture. In the present review, we discuss advances in genetic analysis of barley shoot architecture, focusing on tillering, leaf size and angle. We also discuss novel phenotyping techniques, such as 2D and 3D imaging, that have been introduced in the era of phenomics, facilitating reliable trait measurement. We discuss the identification of genes and pathways that are involved in barley tillering and leaf development, highlighting key hormones involved in the control of plant architecture in barley and rice. Knowledge on genetic control of traits related to plant architecture provides useful resources for designing ideotypes for enhanced barley yield and performance.

“…These have been reported to be secretory (Bowden 1971), with the cells containing a variety of sugars and pectic substances. However, the number of species investigated is tiny, and macrohairs would repay closer investigation (Sylvester and Smith 2009). …”

“…The region of active division, termed the "proliferative zone" by Sylvester and Smith (2009), is later divided into two by the developing ligule and sheath, so that two meristems are formed, one each at the base of the blade and the base of the sheath.…”
