Visual damage ratings, thrips counts, and seedling dry weights were recorded at 2.5, 3.5, and 4.5 wk after planting, respectively. Population density and thrips arrival times varied between years. Data from the three separate damage scoring dates provided a better estimate of resistance or susceptibility to thrips than ratings from the individual dates over the season. Tobacco thrips [Frankliniella fusca (Hinds) (Thysanoptera: Thripidae)], followed by western flower thrips [Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)], were the dominant thrips species observed in the study. Five resistant G. barbadense accessions and five moderately resistant upland cotton accessions were identified from field evaluations. Greenhouse experiments were conducted in Fall 2015 and Spring 2016 to determine if plant height, growth rate, leaf pubescence, and leaf area were significantly different in resistant and susceptible groups of G. hirsutum and G. barbadense accessions identified from the field screenings. Leaf pubescence and relative growth rate were significantly higher in resistant accessions compared with susceptible accessions in absence of thrips. There was no difference for plant height and leaf area between resistant and susceptible groups. Results suggest thrips-resistant plants have a possible competitive advantage through faster growth and higher trichome density, which limits thrips movement.}, number={5}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, publisher={Oxford University Press (OUP)}, author={Kaur, Baljinder and Kuraparthy, Vasu and Bacheler, Jack and Fang, Hui and Bowman, Daryl T.}, year={2018}, month={Oct}, pages={2426–2434} }

Genotyping the diversity panel using 122 SSRs detected 143 marker loci. A total of 819 alleles were identified across 143 markers loci, and out of these, 23.3% were unique alleles, observed only in one accession. Average genetic distance between accessions was 0.36, suggesting higher levels of genetic variation present in the cotton tropical landrace germplasm. Using Bayesian model‐based structure analysis, five major subgroups were identified that roughly corresponded to the geographical origins of accessions. Substantial admixture was observed as accessions from different geographical locations were grouped together. Results from phylogenetic analysis, principal component analysis, and analysis of molecular variance supported clustering based on STRUCTURE analysis. Pairwise kinship estimates suggested that most of the accessions were unrelated. Finally, core sets representing various levels of allelic richness were identified using POWERMARKER. Assessing genetic diversity, population structure, and identifying the core sets in the landraces will facilitate the utilization of unexploited tropical genetic diversity towards developing improved cotton cultivars.}, number={5}, journal={CROP SCIENCE}, author={Kaur, Baljinder and Tyagi, Priyanka and Kuraparthy, Vasu}, year={2017}, pages={2457–2470} }

With its diploid genome, publicly available genome sequence, adapted growth, and developmental and agronomic attributes, G. arboreum could make an ideal cotton species to study the genetic basis of biological traits that are controlled by orthologous loci in diploid and polyploid species. Leaf shape is an important agronomic trait in cotton. Normal, subokra, okra, and laciniate are the predominant leaf shapes in cotton cultivars. Laciniate in diploids is phenotypically similar to okra leaf shape in tetraploid. In the present study, a population of 135 F2 plants derived from accessions NC 501 and NC 505 was used for genetic and molecular mapping of laciniate leaf shape in diploid cotton (G. arboreum). An inheritance study showed that laciniate leaf shape was controlled by a single incompletely dominant gene (LL–A2). Molecular genetic mapping using simple‐sequence repeat (SSR) markers placed the leaf shape locus L‐A2 on chromosome 2. Targeted mapping using putative genes from the delineated region established that laciniate leaf shape in G. arboreum and okra leaf shape in Gossypium hirsutum L. were controlled by genes at orthologous loci. Collinearity was well conserved between the diploid A‐ (G. arboreum) and D‐ (G. raimondii Ulbr.) genomes in the targeted genomic region narrowing the candidate region for the leaf shape locus (L‐A2) to nine putative genes. Establishing the orthologous genomic region for the L loci could help use the diploid cotton resources toward map‐based cloning of leaf shape genes in Gossypium.}, number={3}, journal={CROP SCIENCE}, author={Kaur, Baljinder and Andres, Ryan and Kuraparthy, Vasu}, year={2016}, pages={1095–1105} }

By using expression analysis and candidate gene mapping, two LMI1 -like genes are identified as possible candidates for leaf shape trait in cotton. Leaf shape in cotton is an important trait that influences yield, flowering rates, disease resistance, lint trash, and the efficacy of foliar chemical application. The leaves of okra leaf cotton display a significantly enhanced lobing pattern, as well as ectopic outgrowths along the lobe margins when compared with normal leaf cotton. These phenotypes are the hallmark characteristics of mutations in various known modifiers of leaf shape that culminate in the mis/over-expression of Class I KNOX genes. To better understand the molecular and genetic processes underlying leaf shape in cotton, a normal leaf accession (PI607650) was crossed to an okra leaf breeding line (NC05AZ21). An F2 population of 236 individuals confirmed the incompletely dominant single gene nature of the okra leaf shape trait in Gossypium hirsutum L. Molecular mapping with simple sequence repeat markers localized the leaf shape gene to 5.4 cM interval in the distal region of the short arm of chromosome 15. Orthologous mapping of the closely linked markers with the sequenced diploid D-genome (Gossypium raimondii) tentatively resolved the leaf shape locus to a small genomic region. RT-PCR-based expression analysis and candidate gene mapping indicated that the okra leaf shape gene (L (o) ) in cotton might be an upstream regulator of Class I KNOX genes. The linked molecular markers and delineated genomic region in the sequenced diploid D-genome will assist in the future high-resolution mapping and map-based cloning of the leaf shape gene in cotton.}, number={1}, journal={THEORETICAL AND APPLIED GENETICS}, author={Andres, Ryan J. and Bowman, Daryl T. and Kaur, Baljinder and Kuraparthy, Vasu}, year={2014}, month={Jan}, pages={167–177} }
