Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...

Shear-banding is commonly regarded as the "plasticity carrier" of metallic glasses (MGs), which usually causes severe strain localization and catastrophic failure if unhindered. However, through the use of the high-throughput dynamic nanoindentation technique, here we reveal that nano-scale shear-banding in different MGs evolves from a "distributed" fashion to a "localized" mode when the result...

Cytogenetic characterization of D. polymorpha was carried out using banding techniques such as C-banding, fluorochrome CMA3 and silver nitrate treatment. The diploid chromosome number of both investigated D. polymorpha forms (typical and albinotic) was the same 2n = 32 (NF = 56). The karyotype consisted of 5 pairs of metacentric, 7 pairs of submetacentric and four pairs of subtelo-acrocentric c...

Re Glossary Alkylating agent Alkylating agents involve reactions with guanine in DNA. These drugs add methyl or other alkyl groups onto molecules where they do not belong. This in turn inhibits their correct utilization by base-pairing and causes a miscoding of DNA. Aneuploidy The occurrence of one or more extra or missing chromosomes leading to an unbalanced chromosome complement, or any chrom...

BANDING of the pulmonary artery has been proposed as a therapeutic procedure for patients with a large left-to-right shunt and pulmonary artery hypertension not amenable to complete correction. It was theorized that by increasing the resistance to outflow from the right ventricle, and thus lowering the pulmonary artery pressure, the size of the left-to-right shunt would diminish, the high outpu...

Monoclonal and oligoclonal banding has been observed in electrophoretograms of serum, cerebrospinal fluid, and urinary protein from patients infected with the human immunodeficiency virus (HIV). This is the first report of kappa oligoclonal banding in the protein electrophoretograms for urine but not for serum of two patients with the acquired immune deficiency syndrome (AIDS). Both patients ha...

Wormlike micelles are an important class of surfactant micellar architectures that find use in applications ranging from consumer products to energy and nanomaterials. Many wormlike micellar systems exhibit a flow instability known as shear banding, characterized by an inhomogeneous flow field. Although many of the proposed mechanisms and theories for shear banding revolve around fluid microstr...
