Morphological differences among Korean Allium subgenus Rhizirideum sect. Sacculiferum and some related species are minor, making species delimitation difficult. Inter-simple sequence repeat (ISSR) was employed to assess genetic diversity and relationships. Thirty-four accessions, representing six taxa of A. thunbergii, A. sacculiferum, A. deltoides-fistulosum, A. cyaneum var. cyaneum, A. cyaneu...

Plants produce two phosphorylated enzymes: pyrophosphate-dependent fructose-6-phosphate phosphotransferase (PFP) and ATP-dependent phosphofructokinase (PFK). However, the characterization of (PFK) family members their functions remains unexplored in Eastern Cottonwood (Populus deltoides). This study comprehensively analyzed 17 genes P. deltoides genome, including gene structure, conserved domai...

A bending sensor is demonstrated using the combination of a mode-selective photonic lantern (PL) and a multicore fiber. A short section of three-core fiber with strongly coupled cores is used as the bend sensitive element. The supermodes of this fiber are highly sensitive to the refractive index profiles of the cores. Small bend-induced changes result in drastic changes of the supermodes, their...

Previous studies defined easy and difficult to hydrolyze fractions of hemicellulose that may result from bonds among cellulose, hemicellulose, and lignin. To understand how such bonds affect hydrolysis, Populus trichocarpa × Populus deltoides, holocellulose isolated from P. trichocarpa × P. deltoides and birchwood xylan were subjected to hydrothermal flow-through pretreatment. Samples were char...

To aid in the investigation of the Populus deltoides microbiome, we generated draft genome sequences for 21 Pseudomonas strains and 19 other diverse bacteria isolated from Populus deltoides roots. Genome sequences for isolates similar to Acidovorax, Bradyrhizobium, Brevibacillus, Caulobacter, Chryseobacterium, Flavobacterium, Herbaspirillum, Novosphingobium, Pantoea, Phyllobacterium, Polaromona...

cDNA library constructed from male flower buds of Populus deltoides Bartr. ex Marsh. According to an analysis of genomic DNA structure and putative protein structure, and a phylogenetic study, PdPI is an ortholog of the Arabidopsis PI gene. Relative-quantitative real-time polymerase chain reaction analysis showed that PdPI has a broader expression pattern than PI in Arabidopsis. PdPI was strong...

We are interested in the root microbiome of the fast-growing Eastern cottonwood tree, Populus deltoides. There is a large bank of bacterial isolates from P. deltoides, and there are 44 draft genomes of bacterial endophyte and rhizosphere isolates. As a first step in efforts to understand the roles of bacterial communication and plant-bacterial signaling in P. deltoides, we focused on the preval...

Incidence of leaf infestation Populus deltoides Bartr. ex Marsh by the Larvae Phalanta phalantha (Drury) was noticed for first time in forest nursery Jharkhand state. The present findings document a new record host plant (Populus deltoides) this lepidopteron insect from Jharkhand. This is enormously important as promising agroforestry tree species and damage potential phalantha.

ABSTRACT The recently described rust hybrid Melampsora xcolumbiana was discovered as a result of its novel pathogenic variation on Populus trichocarpa x P. deltoides (TxD) hybrid poplar. To characterize this pathogenic variation, 10 commercial TxD clones, all F(1) clones, were chosen as host differentials. Fourteen mononuredinial isolates of Pacific Northwestern field collections of M. xcolumbi...

Populus deltoides, P. nigra, and P. trichocarpa are the most important species for poplar breeding programs worldwide. In addition, Populus has become a model for fundamental research on trees. Linkage maps were constructed for these three species by analyzing progeny of two controlled crosses sharing the same female parent, Populus deltoides cv. S9-2 x P. nigra cv. Ghoy and P. deltoides cv. S9...
