    查看更多>>摘要：Background Weed infestation in cotton has been reported to offer severe competition and cause yield reduc-tion to a large extent.Weeding via cultural practices is time consuming,tedious,and expensive due to long dura-tion of cotton crop and regular monsoon rains during cotton production in India.Chemical weed control has been successfully utilized in cotton in the recent past.However,continuous use of similar herbicides leads to resistance in weeds against herbicides.And when sprayed to the field,herbicides not only suppress weeds but leave undesir-able residues in the soil that are hazardous to the environment.Therefore,a study was performed at cotton research area at Chaudhary Charan Singh Haryana Agricultural University,Hisar,Haryana during two consecutive kharif seasons(2020 and 2021)to determine the most suitable and sustainable weed management strategy through the integration of chemical and cultural methods.Results Mulching with rice straw of 7.5 t ha-1resulted in significantly higher cotton seed yield(3 189 and 3 084 kg ha-1)and better weed control in comparison to no mulch treatments(2 990 and 2904 kg ha-1)in 2020 and 2021,respectively.Among various weed management levels,the significantly lowest cotton seed yield was recorded in untreated control(1 841 and 1 757 kg·ha-1 during 2020 and 2021,respectively)in comparison to other treatments while all other treatments were statistically at par with each other during both years of crop experimentation.Conclusion Mulching with rice straw of 7.5 t·ha-1 along with a pre-emergence application of pendimethalin(active ingredient)at 1.5 kg·ha-1 fb(followed by)one hoeings at 45 days after sowing(DAS)and fb glyphosate 2 kg·ha-1(Shielded spray)at 90 DAS is a viable option for effective control of grassy and broadleaved weeds in Bt cotton in north-west India.

    查看更多>>摘要：Background Studies on genetic variation and combining ability are essential tools to employ the suitable breed-ing programme,particularly for hybrid production,to exploit the heterosis in cross-pollinated crops like cotton.Thus,combining ability studies in desi cotton(Gossypium arboreum L.)was carried out using 13 diverse parents through dial lei mating design,evaluating 78 F1 hybrids along with their parents,without reciprocals using Griffng's and Hayman's approaches.Results Genotypes H 509,AC 3265,AKH 496,and PBN 565 exhibited superior per se performance,indicating their potential use as parents in future breeding programs to develop superior hybrids.The general combining abil-ity(GCA)effect of the genotypes revealed that AC 3097 and AKA 13-SP1 were good general combiners for most traits in this study.Genotypes PBS 1127-SP1,AKH 496,H 509,N11-54-31-32,and AKA 13-SP1 exhibited strong combining ability,contributing to a significant specific combining ability(SCA)effect in seven selected crosses(AC 3265 × PBS 1127-SP1,AKH 496 × H 509,AKH 496 × AC 3097,PBS 1127-SP1 × N11-54-31-32,AC 3216 × AKA 13-SP1,H 503 × N11-54-31-32,and H 509× AKA 13-SP1)for yield improvement.These crosses showed positive heterosis in a positive direction.Conclusion From the present study,five genotypes(AC 3097,AKA 13-SP1,N11-54-31-32,AC 3265,and H 509)were identified as good general combiners for producing hybrids,and seven combinations showed a promising hybrid for future breeding programs.

    查看更多>>摘要：Background Aphis gossypii(Hemiptera:Aphididae)is a worldwide polyphagous phloem-feeding agricultural pest,and it can produce offspring by sexual or asexual reproduction.Compared with dozens of generations by partheno-genesis,sexual reproduction is performed in only one generation within one year,and little is known about the sexual reproduction of A.gossypii.In this study,sexual females of A.gossypii were successfully obtained through a previ-ously established induction platform,and the morphological characteristics,developmental dynamics,and temporal gene expression were examined.Subsequently,signaling pathways potentially involved in regulating the growth,development,and reproduction of sexual females were investigated.Results The morphological observation showed that from the 1st instar nymph to adult,sexual females exhibited a gradually deepened body color,an enlarged body size,longer antennae with a blackened end,and obviously pro-truding cauda(in adulthood).The anatomy found that the ovaries of sexual females developed rapidly from the 2nd instar nymph,and the embedded oocytes matured in adulthood.In addition,time-course transcriptome analysis revealed that gene expression profiles across the development of sexual females fell into 9 clusters with distinct pat-terns,in which gene expression levels in clusters 1,5,and 8 peaked at the 2nd instar nymphal stage with the largest number of up-regulated genes,suggesting that the 2nd instar nymph was an important ovary development period.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis revealed that a large number of genes in the sexual female adult were enriched in theTGF-beta signaling pathway and Forkhead box O(FoxO)signaling pathway,highlighting their important role in sexual female adult development and reproduction.Conclusion The morphological changes of the sexual female at each developmental stage were revealed for the first time.In addition,time-course transcriptomic analyses suggest genes enriched in the TGF-beta signaling pathway and FoxO signaling pathway probably contribute to regulating the development and oocyte maturation of sexual females.Overall,these findings will facilitate the regulating mechanism research in the growth and development of sexual females by providing candidate genes.

    查看更多>>摘要：The situation of global warming imparts negative impacts on crop growth and development.Cotton is the most important fiber crop around the globe.However,frequent drought episodes pose serious threats to cotton produc-tion worldwide.Due to the complex genetic structure of drought tolerance,the development of a tolerant cultivar is cumbersome via conventional breeding.Multiple omics techniques have appeared as successful tool for cot-ton improvement in drought tolerance.Advanced omics-based biotechniques have paved the way for generation of omics data like transcriptomics,genomics,metabolomics and proteomics,which greatly expand the knowledge of cotton response to drought stress.Omics methodologies and have provided ways for the identification of quan-titative trait loci(QTLs),gene regulatory networks,and other regulatory pathways against drought stress in cotton.These resources could speed up the discovery and incorporation of drought tolerant traits in the elite genotypes.The genome wide association study(GWAS),gene-editing system CRISPER/Cas9,gene silencing through RNAi are effi-cient tools to explore the molecular mechanism of drought tolerance and facilitate the identification of mechanisms and candidate genes for the improvement of drought tolerance in cotton.

    查看更多>>摘要：Cotton,an important industrial crop cultivated in more than 70 countries,plays a major role in the livelihood of millions of farmers and industrialists.Cotton is mainly grown for its fiber,an economic component that can be differentiated from its epidermal cells in the outer integument of a developing seed.Fiber length,fiber strength,and fiber fineness are three main attributes that contribute to the quality of cotton fibers.Recent advancements in genomics have identi-fied key genes,which are the most important factors that govern these three traits,can be introduced into cultivars of interest via gene editing,marker-assisted selection,and transgenics,thus the narrow genetic background of cotton can be addressed and its fiber quality traits can be enhanced.Over the past two decades,quantitative trait loci(QTLs)have been mapped for different fiber traits,approximately 1 850 QTLs have been mapped for fiber length,fiber strength,and fineness among which a few genes have been edited for quality improvement in cotton.In this back-ground,the current review covers the development and the factors that influence these traits,along with the reported genes,QTLs,and the edited genomes for trait improvement.

    查看更多>>摘要：Background:Potassium(K)deficiency has become a common field production problem following the widespread adoption of Bacillus thuringiensis(Bt)transgenic cotton(Gossypium hirsutum L.)worldwide.The purpose of this study was to clarify whether the introduction of Bt gene directly reduces the K-use efficiency of cotton to induce K deficiency.Results:The cotton variety,Jihe 321(wild type,WT)and its two Bt(Cry 1Ac)-transgenic overexpression lines(OE-29317,OE-29312)were studied in field with low soil-test K+(47.8 mg·kg-1).In the field with low soil-test K+,only OE-29317 had less biomass and K+accumulation than the WT at some growth stages.Both Bt lines produced similar or even greater seed cotton yield than WT in the field.When the Btgene(～70％)in OE-29317 and OE-29312 plants was silenced by virus-induced gene silencing(VIGS),the VIGS-Bt plants did not produce more biomass than VIGS-green fluorescent protein(control)plants.Conclusions:The introduction of Btgene did not necessarily hinder the K use efficiency of the cotton lines under this study.

    A nonsynonymous mutation in an acetolactate synthase gene(Gh_D10G1253)is required for tolerance to imidazolinone herbicides in cotton

    CHEN TianziLING XitieYU YueZHANG Baolong...
    415页
    查看更多>>摘要：Background Herbicide tolerance in crops enables them to survive when lethal doses of herbicides are applied to surrounding weeds.Herbicide-tolerant crops can be developed through transgenic approaches or traditional mutagenesis approaches.At present,no transgenic herbicide tolerant cotton have been commercialized in China due to the genetically-modified organism(GMO)regulation law.We aim to develop a non-transgenic herbicide-tolerant cotton through ethyl methanesulfonate(EMS)mutagenesis,offering an alternative choice for weed management.Results Seeds of an elite cotton cultivar Lumianyan 37(Lu37)were treated with EMS,and a mutant Lu37-1 showed strong tolerance to imidazolinone(IMI)herbicides was identified.A novel nonsynonymous substitution mutation Ser642Asn at acetolactate synthase(ALS)(Gh_D10G1253)in Lu37-1 mutant line was found to be the potential cause to the IMI herbicides tolerance in cotton.The Ser642Asn mutation in ALS did not present among the genomes of natural Gossypium species.Cleaved amplified polymorphic sequence(CAPS)markers were developed to identify the ALS mutant allele.The Arabidopsis overexpressing the mutanted ALS also showed high tolerance to IMI herbicides.Conclusion The nonsynonymous substitution mutation Ser642Asn of the ALS gene Gh_D10G1253 is a novel identi-fied mutation in cotton.This substitution mutation has also been identified in the orthologous ALS genes in other crops.This mutant ALS allele can be used to develop IMI herbicide-tolerant crops via a non-transgenic or transgenic approach.

    查看更多>>摘要：Background Gossypium hirsutum undergoes rapid clonal propagation to regenerate a mature plant through tissue culture.However,the correlation between cotton leaf regeneration,callus induction,and regeneration ability was still obscure.In this research,cotton leaf regeneration level for 21 accessions in the field(new leaves)was observed after the first harvest,and a comparison between field regeneration level and callus induction with its regeneration capacity(new shoots and roots)for the same 21 accessions was carried out.Agronomic traits,including plant height,leaf area,fresh leaf weight,dry leaf weight,the number of flowers and bolls,and biochemical(proline content)and physiological(chlorophyll and carotenoid content)traits during the flowering stage of 21 upland cotton accessions,were investigated.Result A significant correlation between physiological parameters and callus induction was discovered.Callus induction and regeneration capacity of roots and shoots for hypocotyl,cotyledons,and shoot tip tissues were used to validate field leaf regeneration level after the first harvest.CCRI 24 showed significant leaf regeneration in the field and callus induction capacity through callus induction and regeneration.Conclusion We found a substantial relationship between field regeneration capability and callus induction with its regeneration capacity for the hypocotyl,cotyledons,and shoot tip.The results showed that ZS061,Lumian 378,Jim-ian 863,and ZS065 have the highest moisture retention capacity,while CCRI 24,Liaoyang Duomaomian,and Beizhe Gongshemian have the lowest moisture retention capacity.CCRI 24 has the highest leaf regeneration capacity in the field,while Beizhe Gongshemian has the lowest leaf regeneration capacity.All our result provides a clue for checking the regeneration capacity through leaf regeneration level in the field.
