First Report of Phytophthora cryptogea on Potato Tubers in Turkey

Structure of potato tubers formed during spaceflight.

Potato (Solanum tuberosum L. cv. Norland) explants, consisting of a leaf, axillary bud, and small stem segment, were used as a model system to study the influence of spaceflight on the formation of sessile tubers from axillary buds. The explants were flown on the space shuttle Columbia (STS-73, 20 October to 5 November 1995) in the ASTROCULTURE (TM) flight package, which provided a controlled e...

Probability of Globodera rostochiensis Spread on Equipment and Potato Tubers.

The probability of spreading cysts of Globodera rostochiensis on farming equipment and potato tubers was investigated in naturally infested field plots. The number of cysts recovered from soil that adhered to equipment differed significantly between different pieces of equipment. These differences were related to initial nematode density and, in most cases, to the volume of soil that adhered to...

تنوع ژنتیکی درون‌گونه‌ای Phytophthora cryptogea و P. drechsleri *

گونه‌های Phytophthora drechsleri و P. cryptogea بیمارگرهای گیاهی اُاُمیستی با قرابت فیلوژنتیکی نزدیک هستند. به منظور ارزیابی تنوع ژنتیکی در میان این گونه‌ها، جدایه‌هایی از P. drechsleri و P. cryptogea مربوط به میزبان‌های متفاوت و از مناطق مختلف جهان به همراه جدایه‌هایی از آرایه خویشاوند آنها، P. erythroseptica، از طریق روش  میکروستلایت‌های فزو...

Phylogenetic history of Phytophthora cryptogea and P. drechsleri isolates from floriculture crops in North Carolina greenhouses.

The evolutionary history of Phytophthora cryptogea and P. drechsleri isolates previously collected from floriculture crops in North Carolina commercial greenhouses was explored with coalescent- and parsimony-based analyses. Initially, 68 isolates representing 13 location-host groups were sequenced at multiple loci. Sequences of all isolates within a group were identical. A subset of isolates we...
