A genome-wide identification of the BLH gene family reveals BLH1 involved in cotton fiber development
By Fan Qin on Sep 11, 2020

Biomol - Biotechnology JCR

[Background] Cotton is the world’s largest and most important source of renewable natural fiber. BEL1-like homeodomain (BLH) genes are ubiquitous in plants and have been reported to contribute to plant development. However, there is no comprehensive characterization of this gene family in cotton. In this study, 32, 16, and 18 BLH genes were identif...

World Cotton Day As we have been recently recalled, ICAC has launched the initiative of declaring October 7 as the World Cotton Day. Hopefully, in a couple of days, it will become the new UN World Cotton Day and give us some pride in working on cotton. For sure, the World Cotton Day will be celebrated at various cotton research organizations al...

Global identification of genes associated with xylan biosynthesis in cotton fiber
By Fan Qin on Sep 7, 2020

Biomol - Biotechnology JCR

[Background] Mature cotton fiber secondary cell wall comprises largely of cellulose (> 90%) and small amounts of xylan and lignin. Little is known about the cotton fiber xylan biosynthesis by far. [Result] To comprehensively survey xylan biosynthetic genes in cotton fiber, we identified five IRX9, five IRX10, one IRX14, six IRX15, two FRA8, o...

Development and application of perfect SSR markers in cotton
By Fan Qin on Sep 3, 2020

Biomol - Biotechnology JCR

[Background] This study aimed to develop a set of perfect simple sequence repeat (SSR) markers with a single copy in the cotton genome, to construct a DNA fingerprint database suitable for authentication of cotton cultivars. We optimized the polymerase chain reaction (PCR) system for multi-platform compatibility and improving detection efficiency....

Toward the efficient use of Beauveria bassiana in integrated cotton insect pest management

Crop Protection Pest control PestControl-WestCentralAfrica Croprotection-WestCentralAfrica JCR

[Background] For controlling the resistance to insects, in particular carpophagous and phyllophagous caterpillars, using chemical pesticides has led to contamination of cotton area in Benin. Facing this problem, alternative methods including the use of entomopathogenic fungi as biopesticide could be a sound measure to preserve the environment, biod...

Heritability and correlation analysis of morphological and yield traits in genetically modified cotton
By Fan Qin on Aug 28, 2020

Agronomy & physiology JCR

[Background] Cotton is known for fiber extraction and it is grown in tropical and sub-tropical areas of the world due to having hot weather. Cotton crop has a significant role in GDP of Pakistan. Therefore, the two-years research was conducted to estimate heritability and association among various yield contributing parameters of cotton, i.e., plan...

QTL and genetic analysis controlling fiber quality traits using paternal backcross population in upland cotton
By Fan Qin on Aug 28, 2020

Breeding & Genetic improvement Biomol - Biotechnology JCR

[Background] Genetic improvement in fiber quality is one of the main challenges for cotton breeders. Quantitative trait loci (QTL) mapping provides a powerful approach to dissect the molecular mechanism in fiber quality traits. In present study, F14recombinant inbred line (RIL) population was backcrossed to paternal parent for a paternal backcross...

Overexpressing rice lesion simulating disease 1-like gene (OsLOL1) in Gossypium hirsutum promotes somatic embryogenesis and plant regeneration
By Fan Qin on Aug 7, 2020

Biomol - Biotechnology JCR

[Background] Cotton somatic embryogenesis is difficult or rarely frequent to present, which has limited gene function identification and biotechnological utility. Here, we employed a rice key somatic embryogenesis-related gene, rice lesion simulating disease 1-like gene (OsLOL1), to develop transgenic cotton callus for evaluating its function in ec...

The impact of plant density and spatial arrangement on light interception on cotton crop and seed cotton yield: an overview
By Fan Qin on Jul 28, 2020

Agronomy & physiology JCR

[Abstract] Light attenuation within a row of crops such as cotton is influenced by canopy architecture, which is defined by size, shape and orientation of shoot components. Level of light interception causes an array of morpho-anatomical, physiological and biochemical changes. Physiological determinants of growth include light interception, light u...
