Abstract Genomics promises to enrich the investigations of biology and biochemistry. Current advancements in genomics have major implications for genetic improvement in animals, plants, and microorganisms, and for our understanding of cell growth, development, differentiation, and communication. Significant progress has been made in the understanding of plant genomics in recent years, and the area continues to progress rapidly. Functional genomics offers enormous potential to tree improvement and the understanding of gene expression in this area of science worldwide. In this review we focus on functional genomics of wood quality and properties in trees, mainly based on progresses made in genomics study of Pinus and Populus. The aims of this review are to summarize the current status of functional genomics including: (1) Gene discovery; (2) EST and genomic sequencing; (3) From EST to functional genomics; (4) Approaches to functional analysis; (5) Engineering lignin biosynthesis; (6) Modification of cell wall biogenesis; and (7) Molecular modelling. Functional genomics has been greatly invested worldwide and will be important in identifying candidate genes whose function is critical to all aspects of plant growth, development, differentiation, and defense. Forest biotechnology industry will significantly benefit from the advent of functional genomics of wood quality and properties.
We investigate the relation between simple random walks on repeated barycentric subdivisions of a triangle and a self-similar fractal, Strichartz hexacarpet, which we introduce. We explore a graph approximation to the hexacarpet in order to establish a graph isomorphism between the hexacarpet approximations and Barycentric subdivisions of the triangle, and discuss various numerical calculations performed on the these graphs. We prove that equilateral barycentric subdivisions converge to a self-similar geodesic metric space of dimension log(6)/log(2), or about 2.58. Our numerical experiments give evidence to a conjecture that the simple random walks on the equilateral barycentric subdivisions converge to a continuous diffusion process on the Strichartz hexacarpet corresponding to a different spectral dimension (estimated numerically to be about 1.74).

The incidence of childhood central nervous system tumors in infants is about 6 per 100,000 children with glioma having the highest incidence at 1.38 per 100,000. A study by Wu et al. showed recurrent fusion of the NTRK gene in 10% of non-brainstem high grade glioma in very young children suggesting an oncogenic effect of the NTRK fusion genes. Here we present a rare case of a full-term neonate who was noted to have widely splayed sutures and a bulging fontanelle at birth who was found to have infant-type hemispheric glioma with NTRK1 fusion.
Design/Methods:
Not applicable
Results:
A full-term infant with normal prenatal course, including a 20-week anatomy scan, was born with widely splayed sutures, bulging anterior fontanelle and head circumference >99th percentile (40 cm). Head ultrasound showed severe hydrocephalus and a large intracranial mixed echogenicity lesion in the left cerebral hemisphere with hemorrhage. He had sustained leftward gaze, and video EEG revealed seizures. MRI demonstrated a large 6×7cm lesion, hydrocephalus with subfalcine herniation and mass effect on the brainstem (figure, A–B). He underwent biopsy and ventriculoperitoneal shunt placement. MRI 2 weeks later showed tumor enlargement, obstructive hydrocephalus and severe brainstem compression (figure, C–D). Pathology was consistent with infant-type hemispheric glioma with NTRK1 fusion. Due to the dismal prognosis, the family prioritized palliative care.
Conclusions:
Infant-type hemispheric glioma, previously termed glioblastoma (GBM), is a rare, rapidly-growing congenital tumor, and prenatal imaging is often normal. Mixed-age hemorrhages and diffusion restriction is suggestive of the diagnosis. The neurotrophic tyrosine receptor kinase (NTRK) genes NTRK1, NTRK2, and NTRK3 are involved in infant-type hemispheric gliomas and are typically high grade in histology. A recent study by Torre et al. showed most NTRK-fused gliomas were hemispheric and had a higher prevalence in non-brainstem high grade gliomas in patients younger than 3 years old.
