Sep 11, 2020
[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...

Aug 28, 2020
[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
[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

on
Aug 7, 2020
[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

on
Jul 28, 2020
[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
[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
[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

on
Jun 23, 2020
[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...
