Thicker leaves allow plants to grow in water-limited conditions. However, our understanding of the genetic underpinnings of this highly functional leaf shape trait is poor. We used a custom-built confocal profilometer to directly measure leaf thickness in a set of introgression lines (ILs) derived from the desert tomato Solanum pennellii and identified quantitative trait loci. We report evidenc...

The Amazon is undergoing environmental changes that can cause morphological and physiological in plants. general objective of this study was to evaluate the anatomical eco-physiological features Vouacapoua americana during development Brazilian Amazon. It observed stomata only occur abaxial face. Secretory structures are present throughout leaf blade. In central vein petiole region it xylem occ...

PREMISE OF THE STUDY Portulacaceae is a family with a remarkable diversity in photosynthetic pathways. This lineage not only has species with different C4 biochemistry (NADP-ME and NAD-ME types) and C3-C4 intermediacy, but also displays different leaf anatomical configurations. Here we addressed the evolutionary history of leaf anatomy and photosynthetic pathways in Portulacaceae. METHODS Pho...

The current investigation concluded an anatomical study of the cultivated species Pelargonium graveolens L. 'Hér belong to Geraniaceae family and which as ornamental plant, fresh specimen were collected from different region in Baghdad ,the vegetative parts (leaf, stem petiole) details upper lower epidermis leaf also studied, ordinary epidermal cells stomatal complexes studied term shapes dimen...

To investigate whether leaves of plane trees (Platanus orientalis) are damaged by traffic pollution, trees from a megacity (Mashhad, Iran) and a rural area were investigated. Soil and air from the urban centre showed enrichment of several toxic elements, but only lead was enriched in leaves. Leaf size and stomata density were lower at the urban site. At the urban site leaf surfaces were heavily...
