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...

Unraveling the puzzle of the origin and evolution of cotton A-genome
By Fan Qin on Jul 2, 2020

Biomol - Biotechnology JCR

[Abstract] Gossypium hirsutum, the most widely planted cotton species, its evolution has long been an unsolved puzzle because of its hybrid origin from D-genome and A-genome species. To better understand the genetic component of cotton, Huang et al. recently sequenced and assembled the first A1-genome G. herbaceum, and updated the A2-genome G. arbo...

Applying plant-based irrigation scheduling to assess water use efficiency of cotton following a high-biomass rye cover crop
By Fan Qin on Jul 2, 2020

Agronomy & physiology Agro-Physio-north-america JCR

[Background] This study addressed the potential of combining a high biomass rye winter cover crop with predawn leaf water potential (ΨPD) irrigation thresholds to increase agricultural water use efficiency (WUE) in cotton. To this end, a study was conducted near Tifton, Georgia under a manually-controlled, variable-rate lateral irrigation system us...

Genotypic variance in 13C-photosynthate partitioning and within-plant boll distribution in cotton
By Fan Qin on Jun 23, 2020

Agronomy & physiology Agro-physio-Asia Breeding JCR

[Background] Photosynthate partitioning and within-plant boll distribution play an important role in yield formation of cotton; however, if and how they interact to mediate yield remains unclear. The objective of this study was to investigate the genotypic variance in photosynthate partitioning and within-plant boll distribution, with a focus on th...
