The fern flora of the world (Pteridophyta) has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists. Cercosporoid fu...
Carrot purple leaf disease was first reported in 2006 in the state of Washington and was associated with Spiroplasma citri. The disease also was reported in California in 2008. The objectives of this work were to fulfill Koch's postulates and to determine 1) whether the beet leafhopper, Circulifer tenellus (Baker) (Hemiptera: Cicadellidae), transmits carrot [Daucus carota L. subsp. Sativus (Hof...
Plant pathogenic bacteria utilize an array of effector proteins to cause disease. Among them, transcriptional activator-like (TAL) effectors are unusual in the sense that they modulate transcription in the host. Although target genes and DNA specificity of TAL effectors have been elucidated, how TAL proteins control host transcription is poorly understood. Previously, we showed that the Xanthom...

Australia Agaricus pateritonsus soil, Curvularia fraserae dying leaf Bothriochloa insculpta millisiae yellowing tips Cyperus aromaticus Marasmius brunneolorobustus well-rotted wood, Nigrospora cooperae necrotic Heterop...
کلادوسپوریوم یکی از جنس های بزرگ هیفومیست ها است که گونه های آن اغلب به صورت ساپروفیت در خاک و یا روی مواد گیاهی خشک رشد می کنند. بیمارگر گیاهان یا هایپرپارازیت سایر قارچ ها هستند. علی رغم پراکنش وسیع اعضای این جنس، در بسیاری از مناطق اطلاع چندانی از وضعیت گونه های آن در دست نیست. به منظور شناسایی تاکسونومیکی و تجزیه و تحلیل فیلوژنتیکی گونه های کلادوسپوریوم و شبه کلادوسپوریوم در استان گیلان، طی...

Plant Dis. 96:18-23. Temperature has been shown to have a significant effect on development of liberibacter species associated with citrus Huanglongbing disease. ‘Candidatus Liberibacter africanus’ and ‘Ca. ...
