“…Meanwhile, resistance breakdown along with emergence of new strains of insect pests remains major challenge for cotton breeders (Abro et al 2004;Men et al 2005). In this regard, the targeted genome editing could be vital to develop resilient cotton against bollworms (Boopathi et al 2015).…”

Cotton is the prime natural fiber with economic significance globally. Cotton farming and breeding have a long history in Pakistan. The development of high yielding upland cotton (Gossypium hirsutum) varieties gradually replaced the cultivation of diploid Gossypium species. Climate change along with emergence of new epidemic diseases caused yield loss in recent years. The biotic stress considerably reduced the performance and yield potential of cotton. Suitable breeding strategies are essential to generate useful genetic variations and to identify desired traits. Conventional breeding has remarkably increased cotton yield and fiber quality, which has cultivated the NIAB-78, S-12, MNH‐786, and FH‐Lalazar like cultivars. However, this phenotypic selection based breeding method has low efficiency to produce stress resilient cotton. The efficiency of traditional breeding has significantly improved by the marker assisted selection technology. Breakthroughs in molecular genetics, bioinformatics analysis, genetic engineering, and genome sequencing have opened new technique routes for cotton breeding. In addition, genetic improvement through quantitative trait loci, transcriptome, and CRISPR/Cas9 mediated genomic editing can provide suitable platform to improve the resistance to stresses induced by bollworms, cotton leaf curl virus, heat, drought, and salt. The approval of transgenic lines harboring triple gene Cry1Ac + Cry2A + GTG are critical for cotton crop. This review has critically discussed the progress and limitations of cotton breeding in Pakistan, and reviewed the utilization of novel genetic variations and selection tools for sustainable cotton production.

“…Major traits such as quality, yield and disease resistance are under the control of multiple genes called "quantitative trait" (Bolek et al, 2016). Identification of markers tightly linked to the quantitative trait loci allows the breeders to easily identify the target trait in early growth stages of plants (Boopathi et al, 2015). The identification of molecular markers linked to CLCuVD resistance has the potential to improve both the efficacy and efficiency of selection in cotton breeding programs.…”

Cotton is a major cash crop cultivated throughout the world for fiber, feed, fuel and food. Globally, it ranked 1st for fiber and 2nd among the oilseed crops. It is cultivated in around 60 countries of the world with an approximate production of 119.8 million bales annually. During its life cycle, cotton is exposed to about 75 destructive diseases from sowing till harvesting. These stresses are responsible for about 50% yield losses annually with a worth of $ 50 billion in the world. Among them, Cotton leaf curl virus disease (CLCuVD) is one of the significant factors responsible for yield reduction worldwide. This disease is caused by cotton leaf cur virus which is mainly acquired and transmitted by the vector Whitefly (Bemisia tabaci). This virus belongs to the family Geminiviridae and genus Begomovirus. Geminiviruses consist of small circular, single stranded DNA encapsidated in a twinned icosahedral pattern. These are either monopartite or bipartite. Bipartite begomoviruses are composed of circular single stranded DNA-A and DNA-B, both these components are essential for the infection in New World while some bipartite begomoviruses are also present in Old World, but differences are still present. Monopartite begomoviruses are composed of circular single stranded DNA-A and satellite molecules (DNA α-satellite and β-satellite), these are essential components for the severity of disease in the Old World. Efforts are underway to develop new strategies to protect the cotton plants against CLCuVD and its viral causal agents. This review helps the reader to better understand the biology of Cotton leaf curl virus (CLCuV), its behavior/interaction with the host Whitefly as well as recent developments being made for the control of cotton leaf curl disease.

“…Falsos positivos também podem ocorrer pelo efeito de uma eventual presença de estrutura populacional, além da identificação de locos epistáticos, que ainda representa um dos maiores desafios da GWAS (SIVASUBRAMANIAN et al 2015). Neste aspecto, o uso do mapeamento de associação aninhada (Nested Association Mapping -NAM), aplicado de forma pioneira no milho, pode minimizar esses problemas por meio de uma abordagem integrada, que combina o mapeamento clássico de QTL e o de associação, além de considerar as estruturas dentro das populações (BOOPATHI et al, 2015;SIVASUBRAMANIAN et al, 2015).…”

RESUMOAtualmente, desenvolvimento da tecnologia de análise genômica de alta resolução e alto rendimento tem a capacidade de gerar informações sobre milhões de pares de bases em um único ensaio, permitindo a detecção de variação em um único nucleotídeo de uma sequência de DNA. Este contexto possibilitou o surgimento de novas abordagens para a seleção assistida por marcadores, dentre elas os estudos de associação genômica ampla (GWAS), que visam o mapeamento genético por meio das associações entre os locos e a característica fenotípica na população e buscam detectar efeitos dos genes sobre os valores genéticos dos indivíduos; e a seleção genômica ampla (GWS), que detecta genótipos favoráveis por meio de informações genotípicas para inferir sobre os valores fenotípicos futuros, ou valores genômicos. Estas técnicas têm sido exploradas por meio de estudos de simulação e aplicação nos programas de melhoramento tradicionais para diversas culturas. Por outro lado, sua aplicação no melhoramento de forrageiras é restrita, especialmente no Brasil, porém com resultados promissores. Neste contexto, este estudo traz uma abordagem conceitual do tema sob a visão da genética quantitativa, buscando evidenciar sua aplicação no melhoramento genético de forrageiras. PALAVRAS-CHAVE: espécies forrageiras, mapeamento genético, marcadores moleculares. ABSTRACTThe development of high-resolution and high-throughput genomic analysis technology now is enable to generate information about millions of base pairs in only one test, allowing detection of single nucleotide variation in a DNA sequence. This context enabled the emergence of new approaches to marker-assisted selection, among them the Genome-Wide Association Studies (GWAS), which aim at genetic mapping through associations between loci and phenotypic characteristics in the population and seek to detect effects of genes on the genetic values of individuals;
