ROOT DISTRIBUTION OF PECAN TREES

Discovery and small RNA profile of Pecan mosaic-associated virus, a novel potyvirus of pecan trees

A novel potyvirus was discovered in pecan (Carya illinoensis) showing leaf mosaic symptom through the use of deep sequencing of small RNAs. The complete genome of this virus was determined to comprise of 9,310 nucleotides (nt), and shared 24.0% to 58.9% nucleotide similarities with that of other Potyviridae viruses. The genome was deduced to encode a single open reading frame (polyprotein) on t...

Verified Root-Balanced Trees

Andersson introduced general balanced trees, search trees based on the design principle of partial rebuilding: perform update operations naively until the tree becomes too unbalanced, at which point a whole subtree is rebalanced. We define and analyze a functional version of general balanced trees which we call root-balanced trees. Using a lightweight model of execution time, amortized logarith...

DNA analysis of soil extracts can be used to investigate fine root depth distribution of trees

Understanding the root distribution of trees by soil coring is time -: consuming as it requires the separation of roots from soil and classification of roots into particular size classes. This labour-intensive process can limit sample throughput and therefore sampling intensity. We investigated the use of quantitative polymerase chain reaction (qPCR) on soil DNA extractions to determine live fi...
