We present a genome assembly from an individual male Cosmia trapezina (dun-bar pinion; Arthropoda; Insecta; Lepidoptera; Noctuidae). The sequence is 825 megabases in span. majority of the (99.87%) scaffolded into 32 chromosomal pseudomolecules with Z chromosome assembled. complete mitochondrial was also assembled and 15.4 kilobases length.

Abstract Background Chromosome segment substitution lines (CSSLs) can be used to dissect complex traits, from which single-segment (SSSLs) containing a target quantitative trait loci (QTL) developed, and they are thus important for functional analysis molecular breeding. Results A rice line with short wide grains, CSSL-Z563, was isolated advanced-generation backcross population (BC 3 F 6 ) deri...

the chromosome number and type as well as karyotype in vimba vimba persa were studied. a total of 200 larvae and 10 fingerlings of this species with an average weight of 30.2g obtained from shahid ansari fish hatchery. to arrest mitosis in metaphase, larvae under study were placed in a 0.05% solution of colchicine for a period of 6h while the fingerlings were given an intramuscular injection of...

A clearly definable upper tolerance limit for chromosome arm length has been found. As a rule we postulate that, for normal development of an organism, the longest chromosome arm must not exceed half of the average length of the spindle axis at telophase. Above this length, fertility and viability of the carrier individuals become severely impaired due to increasingly incomplete separation of t...

salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...
