N two other papers in this series (GERSTEL 1956; GERSTEL and PHILLIPS in prep.) I the segregation of artificial hexaploid combinations was described. These had been obtained by crossing tetraploid New World cottons with diploid Wild American species and subsequent doubling of the chromosome number. For certain characters these hexaploids were of duplex genotype (i.e. of the type ZZzz). Segregat...
Iqbal, M., M. NaeeM, U. azIz, J. afzal and M. alaM KhaN, 2014. an overview of cotton leaf curl virus disease, persistant challeng for cotton production. Bulg. J. Agric. Sci., 20: 405-415 Cotton leaf curl virus (ClCuV) disease is crucial threat for cotton production in Pakistan. ClCuV belongs to genus Begomovirus of Geminiviridae family and is transmitted by Bemisia tabaci. Drastic reduction in ...
Terpenes are the largest and most diverse class of secondary metabolites in plants and play a very important role in plant adaptation to environment. 3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is a rate-limiting enzyme in the process of terpene biosynthesis in the cytosol. Previous study found the HMGR genes underwent gene expansion in Gossypium raimondii, but the characteristics an...

Biotic pollination is typically a mutualism between plants and their pollinators, where each partner receives benefit. However, can resort to various reproductive strategies attract pollinators. Within angiosperms, group of known as endoparasites comprised only flowers or inflorescences. These exhibit strategies, such different sexual systems attractants, most are dependent on animals for polli...

Calcineurin B-like (CBL) proteins, as calcium sensors, play pivotal roles in plant responses to diverse abiotic stresses and in growth and development through interaction with CBL-interacting protein kinases (CIPKs). However, knowledge about functions and evolution of CBLs in Gossypium plants is scarce. Here, we conducted a genome-wide survey and identified 13, 13 and 22 CBL genes in the progen...
Approximately 185,000 Gossypium EST sequences comprising >94,800,000 nucleotides were amassed from 30 cDNA libraries constructed from a variety of tissues and organs under a range of conditions, including drought stress and pathogen challenges. These libraries were derived from allopolyploid cotton (Gossypium hirsutum; A(T) and D(T) genomes) as well as its two diploid progenitors, Gossypium arb...
BACKGROUND AND AIMS Gossypium is an economically important, globally distributed taxon comprising more than 50 species. DNA content estimates from about half of the species indicate over a 3-fold variation exists. However, the nine DNA content estimates for G. hirsutum reveal over a 2-fold difference for this species alone. Recent reports have shown that several plant compounds can bias DNA con...
