Sexual Organs of Marchantia polymorpha
A total of 935 expressed sequence tags (ESTs) from male immature sexual organ were determined, of which 600 ESTs were assembled into 110 non-redundant groups, resulting in 445 unique EST sequences. Of these, 244 sequences shared significant similarities to known nucleotide or amino acid sequences in other organisms. The remaining 201 unique sequences showed no significant matches and thus are l...
متن کاملChemical stimulation of sexual reproduction in Phytophthora and Pythium
The genera of Phytophthora and Pythium are two of the very destructive groups of plant pathogens in the world (Plaats-Niterink, 1981; Erwin and Ribeiro, 1996). They attack mainly mature plants and young seedlings, respectively, of forest, fruit, vegetable, flower, and ornamental species. These two groups of fungi are classified in the family Pythiaceae of the Oomycetes, which is excluded from t...
متن کاملMRI of female genital and pelvic organs during sexual arousal.
We utilized contrast enhanced magnetic resonance imaging (MRI) to delineate the anatomy of the female genital and pelvic organs during sexual arousal. Eleven healthy pre-menopausal women and eight healthy post-menopausal women underwent MRI of the pelvis while watching an erotic video. A 1.5 Tesla MR system was used to produce T1-weighted images following administration of MS-325, a gadolinium-...
متن کاملEffect of culture origin on chemical stimulation of sexual reproduction in Phytophthora and Pythium
Lecithin washed with NaCl solution was stimulatory to oospore formation of Phytophthora boehmeriae, P. sojae, P. cactorum, and Pythium aphanidermatum. Commercial glycerides of palmitic acid with 99% purity were found to contain a substance inhibitory to oospore formation. Purification with florisil column chromatography was more effective in removing the inhibitory substance than thin-layer chr...
متن کاملMefenoxam Insensitivity and the Sexual Stage of Phytophthora capsici in Michigan Cucurbit Fields.
ABSTRACT The potential for outcrossing, occurrence of oospores, and inheritance of mefenoxam sensitivity was assessed in naturally occurring populations of Phytophthora capsici. Between 1997 and 1998, 14 farms were sampled, with 473 isolates recovered from cucurbit hosts and 30 from bell pepper. The A1 and A2 compatibility types were recovered in a roughly 1:1 ratio in 8 of 14 farms with sample...
