The water pipes of elongating plant organs are the result of programmed cell death and are formed by the walls of dead and empty protoxylem elements. These protoxylem elements are passively elongated many times by the surrounding tissue before they are replaced and collapse. Well-known adaptations for this unique task include the characteristic secondary wall thickenings, forming rings and heli...

Jatropha integerrima Jacq. (Euphorbiaceae) is an erect ornamental shrub, native to West Indies. The plant has numerous applications in traditional medicine but there is a lack of data related to the standards of roots of the plant. So pharmacognostical study and parameters related to physico-chemical properties have been assessed. Macroscopy and microscopy of transverse section were performed. ...

Spatial control of cell-wall deposition is essential for determining plant cell shape [1]. Rho-type GTPases, together with the cortical cytoskeleton, play central roles in regulating cell-wall patterning [2]. In metaxylem vessel cells, which are the major components of xylem tissues, active ROP11 Rho GTPases form oval plasma membrane domains that locally disrupt cortical microtubules, thereby d...

The maize (Zea mays L.) Aux/IAA protein RUM1 (ROOTLESS WITH UNDETECTABLE MERISTEMS 1) controls seminal and lateral root initiation. To identify RUM1-dependent gene expression patterns, RNA-Seq of the differentiation zone of primary roots of rum1 mutants and the wild type was performed in four biological replicates. In total, 2 801 high-confidence maize genes displayed differential gene expressi...

Background: In the world, great importance is attached to intensification of plants. To date, most medicinal plants are only partially used. case Colchicum autumnale L. currently mainly corms used for extraction alkaloids. The purpose this study was investigate use perspective plant reported from area. This article examines anatomy and phytochemistry leaf corm C. autumnale, which grown as a cro...

Peripheral nerve injuries (PNI) can lead to lifetime loss of function and disfigurement. Different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. Designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. Utilization of absorbable and non-absorb...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...

There is a large body of information relating to the ontogeny, development and the vasculature of eudicotyledonous leaves. However, there is less information available concerning the vascular anatomy of monocotyledonous leaves. This is surprising, given that there are two uniquely different phloem systems present in large groups such as grasses and sedges. Monocotyledonous leaves contain margin...

The distribution of (14)C from xylem-borne [(14)C]glutamine, the major nitrogen compound moving in xylem sap of cottonwood (Populus deltoides Bartr. ex Marsh), was followed in rapidly growing shoots with a combination of autoradiographic, microautoradiographic, and radioassay techniques. Autoradiography and (14)C analyses of tissues showed that xylem-borne glutamine did not move with the transp...
