Root hairs are an excellent model system to study cell developmental processes as they are easily accessible, single-celled, long tubular extensions of root epidermal cells. In a genetic approach to identify loci important for root hair development, we have isolated eight der (deformed root ...

Different alpha-tubulin cDNA sequences fused in an antisense orientation to a CaMV 35S promoter were introduced into Arabidopsis thaliana plants. Several independent transgenic lines that showed a moderate but clear reduction of alpha-tubulin gene expression (TUA6/AS lines) were obtained and phenotypically characterized. Although no apparent abnormalities were detected in the ...
Two cases of anomalous development of the upper third premolar in a dog and a cat are described. The involved teeth have a bifid crown and 3 roots. The central root is abnormally wide and has 2 separate root canals. The anomalous tooth is the cause of malocclusion in the cat and of ...
Crown roots are main components of the fibrous root system and important for crops to anchor and absorb water and nutrition. To understand the molecular mechanisms of crown root formation, we isolated a rice mutant defective in crown root emergence designated as Oscand1 (named after the Arabidopsis homologous gene ...

Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and ...

Two recessive mutant alleles at CAN OF WORMS1 (COW1), a new locus involved in root hair morphogenesis, have been identified in Arabidopsis thaliana L. Heynh. Root hairs on Cow1- mutants are short and wide and occasionally formed as pairs at a single site of hair formation. The COW1 locus maps to chromosome 4. Root hairs on Cow1- plants ...
A passive, microcomputer based diagnostic-monitoring system has been developed to continuously monitor thirty-two critical-boiler-state variables and to predict the root cause of abnormal behavior in the boiler processes and control system. The developmen...

The RADICAL-INDUCED CELL DEATH1 and SIMILAR TO RCD ONE1 genes of Arabidopsis thaliana encode members of the poly(ADP-ribose) polymerase (PARP) superfamily and have pleiotropic functions in development and abiotic stress response. In order to begin to understand the developmental and molecular bases of the defects seen in rcd1-3; sro1-1 plants, this study used the ...

The inoculation of the European Alnus glutinosa host plant by a pure culture of an actinomycete isolated from the North American Comptonia peregrina root nodule was successful. Fluorescein-labeled antibodies, specific against the actinomycetal isolate of the C. peregrina root nodule, demonstrated the identity of this actinomycete in the resulting Alnus ...
We have identified a gene, Lateral Root Development 3 (LRD3), important for maintaining a balance between primary and lateral root growth. The lrd3 mutant has decreased primary root growth and increased lateral root growth. We determined that the LRD3 gene encodes a LIM-domain protein of ...
Infection of alfalfa with Rhizobium meliloti exo mutants deficient in exopolysaccharide results in abnormal root nodules that are devoid of bacteria and fail to fix nitrogen. Here we report further characterization of these abnormal nodules. Tightly curled root hairs or shepherd's crooks were found after ...

Two pea (Pisum sativum L.) symbiotic mutants SGEFix(-)-1 (sym40) and SGEFix(-)-2 (sym33) with abnormalities in infection thread development and function in symbiotic root nodules have been characterised in terms of mycorrhizal colonisation of roots, shoot and root biomass accumulation and shoot ...
Studies on human patients and animal models of disease have shown that disruptions in prenatal and early postnatal brain development are a root cause of mental retardation. Since proper brain development is achieved by a strict spatiotemporal control of neurogenesis, cell migration, and patterning of synapses, ...
