The vascular wilt fungi Verticillium dahliae and V. albo-atrum infect over 200 plant species, causing billions of dollars in annual crop losses. The characteristic wilt symptoms are a result of colonization and proliferation of the pathogens in the xylem vessels, which undergo fluctuations in osmolarity. To gain insights into the mechanisms that confer the organisms' pathogenicity and enable th...
The article presents the herbicidal, defoliating, fungicidal properties of synthesized derivatives benzoxazolinones and benzoxazolinethions. It was shown that 3-alkylbenzoxazolinones, 3-alkyl-6-halobenzoxazolinones 2-alkylthiobenzoxazoles exhibit herbicidal action during growing season plants, they also cause cotton leaves to drop up 70%. found 3-alkylbenzoxazolinones exhibited activity against...
Conidia were germinated at three temperatures in media in which available water, expressed as water activity, was controlled at three levels. Rate of germination in the basal medium (0.9964 water activity) was most rapid at 25 C and was inhibited at 15 and 30 C. Lowering the water activity at a particular temperature decreased rates of germination. However, at a low water activity (0.9778) germ...
این بررسی به منظور آگاهی از اثرات جانبی دو علف کش بسیار رایج با کاربرد در خاک تریفلورالین (مایع غلیظ امولسیون شونده 48%) و اتال فلورالین (مایع غلیظ امولسیون شونده 33%) به ترتیب در غلظت های500-0 و 300-0 قسمت در میلیون بر فعالیت زیست شناختی پنج بیمارگر قارچی گیاهچه پنبه (rhizoctonia solani،pythium ultimum ،fusarium moniliforme، alternaria alternata و verticillium dahliae) انجام شد. پارامترهای باز...
Verticillium wilt is a soil-borne disease, and severely limits the development of cotton production. To investigate the role of endophytic fungi on Verticillium wilt, CEF-818 (Penicillium simplicissimum), CEF-714 (Leptosphaeria sp.), CEF-642 (Talaromyces flavus.) and CEF-193 (Acremonium sp.) isolated from cotton roots were used to assess their effects against cotton wilt disease caused by a def...
Understanding the population structure and linkage disequilibrium in an association panel can effectively avoid spurious associations and improve the accuracy in association mapping. In this study, one hundred and fifty eight elite cotton (Gossypium hirsutum L.) germplasm from all over the world, which were genotyped with 212 whole genome-wide marker loci and phenotyped with an disease nursery ...
Circular RNAs (circRNAs), a class of recently discovered non-coding RNAs, play a role in biological and developmental processes. A recent study showed that circRNAs exist in plants and play a role in their environmental stress responses. However, cotton circRNAs and their role in Verticillium wilt response have not been identified up to now. In this study, two CSSLs (chromosome segment substitu...
