Myosin, detected by immunofluorescence using an antibody to bovine skeletal and smooth muscle myosin, has been localised on individual identifiable organelles from the grasses Alopecurus pratensis and Secale cereale, and on the surfaces of vegetative nuclei and generative cells from pollen and pollen tubes of Hyacinthus orientalis and Helleborus foetidus. Taken in conjunction with recent eviden...

BACKGROUND Phlebotomus orientalis Parrot (Diptera: Psychodidae) is the main vector of visceral leishmaniasis (VL) caused by Leishmania donovani in East Africa. Here we report on life cycle parameters and susceptibility to L. donovani of two P. orientalis colonies originating from different sites in Ethiopia: a non-endemic site in the lowlands - Melka Werer (MW), and an endemic focus of human VL...

This research was carried out in order to compare among three different fertilizers: bio, chemical, and organic. on two plants selected conduct this were (Narcissus Hyacinths), which cultivated shaded non-shaded locations from Autumn 2020 Spring 2021 Gerdarash field at the college campus. The vegetative traits of plants, as well production bulblets, measured properly. Regarding Narcissus, bio-f...

Tabular and staghorn corals of the genus Acropora often form low-diversity stands on shallow coral reefs, presumably due to their rapid growth rate and ability to outcompete understorey assemblages. Coral cover underneath the abundant Indo-Pacific tabular coral, Acropora hyacinthus, was four times lower than on the adjacent substratum on the reef crest at Lizard Island on the northern Great Bar...

In this study, esterase isozyme polymorphisms in Boreal-Tertiary origin relict endemic L. orientalis populations were investigated. Four populations located in the Southern and the Southwestern regions of Turkey were screened. Two of these populations (Fethiye-Günlüklü and Fethiye-İnlice) belong to subspecies L. orientalis Mill.var. orientalis. The other two (Muğla-Köyceğiz and Antalya-Gebiz) b...

HE sterility of triploids and other unbalanced polyploids is generally conT ceded to be a consequence of irregularities in the distribution of univalents and multivalents at meiosis. Occasional viable gametes are produced, however, because of nonrandom orientation and segregation of chromosome associations. Thus, SATINA and BLAKESLEE (1937a, b) found a higher frequency of n and 2n chromosome nu...
