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...

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...
Transposable elements (TEs) are a major component of plant genomes. It is of particular interest to explore the potential activation of TE proliferation, especially in hybrids and polyploids, which often are associated with rapid genomic and epigenetic restructuring. Here we explore the consequences of genomic merger and doubling on copia and gypsy-like Gorge3 long terminal repeat (LTR) retrotr...
Understanding the composition, evolution, and function of the Gossypium hirsutum (cotton) genome is complicated by the joint presence of two genomes in its nucleus (AT and DT genomes). These two genomes were derived from progenitor A-genome and D-genome diploids involved in ancestral allopolyploidization. To better understand the allopolyploid genome, we re-sequenced the genomes of extant diplo...
Genetic mapping studies have suggested that diploid cotton (Gossypium) might be an ancient polyploid. However, further evidence is lacking due to the complexity of the genome and the lack of sequence resources. Here, we used the grape (Vitis vinifera) genome as an out-group in two different approaches to further explore evidence regarding ancient genome duplication (WGD) event(s) in the diploid...
