“…Studies on the petal and sepal epidermal micromorphology of leguminous species are rather limited (Christensen and Hansen, 1998;Hammett et al, 1994;Ojeda et al, 2009;Stirton, 1981). Stirton (1981) examined the lateral petals of the papilionoids.…”

“…Stirton (1981) examined the lateral petals of the papilionoids. Hammett et al (1994) reported the epidermal type of the dorsal and lateral petals in 2 Lathyrus species, and Ojeda et al (2009) reported the epidermal types on the dorsal, lateral, and ventral petals of 7 species of the same genus.

In this study, the epidermal types and their distribution on dorsal and lateral petals, the trichome types and their density on sepals of Lathyrus chloranthus, L. digitatus, L. laxiflorus subsp. laxiflorus, L. roseus subsp. roseus, L. sativus, and L. tuberosus, belonging to sections Lathyrus, Lathyrostylis, Pratensis, and Orobon of the genus Lathyrus in Turkey were investigated using light microscopy (LM) and scanning electron microscopy (SEM), and the systematic significance of these characters was evaluated. These taxa, except L. sativus, are studied for the first time under aspects of the petal and sepal micromorphology. Three major epidermal types were recognized on the petal: tabular rugose striate cells (TRS), areolate cells with more or less striations (AS), and papillose conical striate cells (PCS). TRS and AS were further subdivided into three subtypes. TRS was found on the dorsal and lateral petals of L. chloranthus, L. sativus, and L. tuberosus: the dorsal petals of L. roseus subsp. roseus and the lateral petals of L. laxiflorus subsp. laxiflorus, while AS was present on the dorsal and lateral petals of L. digitatus and the lateral petals of L. roseus subsp. roseus. PCS was found only on the dorsal petals of L. digitatus. Three main types of trichomes on the sepal were observed: peltate glandular, capitate glandular, and nonglandular trichomes. The capitate glandular and nonglandular trichomes were further subdivided into three subtypes. The peltate glandular trichomes were present only in L. chloranthus, but absent in the others. The capitate glandular trichomes were found in L. chloranthus, L. laxiflorus subsp. laxiflorus, L. roseus subsp. roseus, and L. tuberosus. The nonglandular trichomes were always present in L. chloranthus and L. laxiflorus subsp. laxiflorus. The present results show that the petal and sepal micromorphology can be used in delimitation of the taxa based on petal and sepal micromorphology.

“…Moreover, some mutants of floral symmetry, such as the peloric mutant in the snapdragon and toadflax, have been reported (Gustafsson, 1979;Luo et al, 1996;Cubas et al, 1999), and there have been some studies on developmental genetics using floral mutants (Yaxley et al, 2001;Benlloch et al, 2003), which have supported the idea that several genes control floral zygomorphy in papilionoid flowers. In addition, Ojeda et al (2009) indicated that epidermal cell shape of petals was different among standard, wing and keel of papilionoid flowers. Considering these results, we hypothesised that the changing number, size and shape of the cells in petals of papilionoid flower implies that the genetic factors involved are more complicated than those in the snapdragon.…”

Information from phylogenetic trees implies zygomorphic flowers have evolved independently from their actinomorphic ancestors several times. There are various types of zygomorphic flowers in the legume subfamilies Caesalpinioideae and Papilionoideae. To understand the relationship between the cell number and size in the petals of zygomorphic flowers, the comparative morphology and anatomy of flower petals were examined in Cercis chinensis and Caesalpinia decapetala var. japonica in Caesalpinioideae, and Lespedeza formosa subsp. velutina and Pueraria lobata in Papilionoideae. Increased petal size is correlated to a higher number and/or size of the cells of the petal in Caesalpinioideae. The characteristics flower morphology of the Papilionoideae has evolved by increased cell numbers, although the cell size was the smallest. Papilionoideae has characteristic papilionoid flowers consisting of five specialised petals. These characteristic morphologies were generated from the complicated changing pattern of cells in petals in the course of legume diversification.

Background and objectives: Micromorphological and elemental information on pulse cotyledon topographies is an essential aspect in identifying grain physiological and structural interactions at cotyledon-seed coat (abaxial) and cotyledon-cotyledon (adaxial) interfaces, which can influence grain quality and processing behavior in food industry applications. The objective of this study was to characterize the topographies of the abaxial and adaxial surfaces of two cultivars each of faba bean, chickpea, field pea, and lentil via micromorphological and elemental analyses.Findings: Scanning electron microscopic imaging of the abaxial and adaxial cotyledon surfaces showed gentle undulation of either tabular-or polygonalshaped epidermal cells that were projected as flat or rugose. They were covered by epicuticular wax films, which had smooth, striate, or granular micromorphology. Elemental results confirmed the presence of C, O, K, Ca, and Mg as the key elements on both cotyledon abaxial and adaxial surfaces.Conclusions: Abaxial and adaxial cotyledon topographies of all the cultivars confirmed varietal differences associated with their micromorphological characteristics. It can be concluded that both abaxial and adaxial surfaces are cemented by a complex cuticle layer of similar elemental composition with a few significant (p < .05) variations. The ease of milling/pearling of pulses could be directly associated with the species, cultivar, architecture, micromorphology, and elemental composition of the pulse cotyledon abaxial and adaxial surfaces.Significance and novelty: These findings will not only assist in interpreting the differences observed in the processing behavior of different pulse species and cultivars but will also enhance our understanding of the process design, targeting pearling of pulses for value-added food applications.
