Pectin synthesis and modification are vital for plant development, although the underlying mechanisms are still not well understood. Here, we report the functional characterization of the OsTSD2 gene, which encodes a putative methyltransferase in rice. All three independent T-DNA insertion lines of OsTSD2 displayed dwarf phenotypes and serial alterations in different zones of the root. These al...

The results of the study leaf structure in psammophyte Corynephorus canescens, which grew under controlled conditions and flooding using methods light microscopy, scanning electron laser confocal are presented. This revealed common distinctive signs morphological anatomical parameters C. canescens leaves phase vegetative growth. Among features were shape size laminas, hypostomatic type leaf, is...

Abstract Intraspecific trait variability (ITV) can be considerably high and reveal plant local adaptation. The aim of this study is to investigate ITV leaf traits (including petioles) in a rooted floating-leaved macrophyte ( Nuphar lutea ) at the scale. We expected see changes resource-use strategies relation water sediment properties. 96 leaves were sampled hyper-eutrophic shallow lake central...

Most species of the modern family Isoëtaceae (Quillworts) some other modern hydrophytes, use a metabolic pathway for carbon fixation that involves uptake of sedimentary carbon and enrichment of CO(2) in internal gas spaces as a carbon-concentrating mechanism. This metabolism, which is related to 'aquatic CAM', is characterized by morphological, physiological and biochemical adaptations for decr...

chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. the tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. radiographic features show typical characteristics and this tumor often presents as a lobul...

water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of sb university of kerman using five wheat cultivars.xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. results showed that significant difference exists...
