Abstract:
Abstract Variation of female and male strobilus production among clones over 4 consecutive years was estimated, and genetic variance, heritability, and genetic correlation in strobilus production were investigated in the second-generation seed orchard of Pinus thunbergii. This seed orchard was created with grafts selected according to the volume growth of their offspring. The production of female strobili continued to increase, whereas the production of male strobili fluctuated throughout the investigated period. The number of female strobili was highest in rich cone years, but the production

Abstract:
The economic value of Humulus lupulus L. (hop) is recognized, but the primary metabolism of the hop strobilus has not been quantified in response to elevated CO2. The photosynthetic contribution of hop strobili to reproductive effort may be important for growth and crop yield. This component could be useful in hop breeding for enhanced performance in response to environmental signals. The objective of this study was to assess strobilus gas exchange, specifically the response to CO2 and light. Hop strobili were measured under controlled environment conditions to assess the organ’s contribution

Abstract:
Japanese cedar (Cryptomeria japonica) is the most important timber species in Japan; however, its pollen is the primary cause of pollinosis in Japan. The total number of pollen grains produced by a single tree is determined by the number of male strobili (male flowers) and the number of pollen grains per male strobilus. While the number of male strobili is a visible and well-investigated trait, little is known about the number of pollen grains per male strobilus. We hypothesized that genetic and environmental factors affect the pollen number per male strobilus and explored the factors that aff

Abstract:
A new taxon of heterosporous lycopsid strobilus, Moscvostrobus mirabile gen. et sp. nov. is described from a clay shale of the Serpukhovian (Namurian, Lower Carboniferous) deposits in the Zaborie quarry, located near the town of Serpukhov, Moscow Region, Russia. The strobilus is preserved in natural connection to the leafy branch, attached to a shoot. The outer surface of the shoot has a thin longitudinal ribbing. Small subtriangular leaves are helically arranged on the shoot. The strobilus has a spherical shape, which is unusual for Carboniferous lycopods. The apex is round and base is wedge-

Abstract Western redcedar (Thuja plicata Donn) foliar-applied gibberellin A3 (GA3) induction trials were performed over a 4-year period at a number of different seed orchards in coastal British Columbia. The effects of GA3 timing, concentration, and frequency on male and female strobilus production, as well as timing on seed quality, were studied. Male and female strobili were induced over the complete span of shoot elongation from May to August, indicative of a less-precise induction period than species in the Pinaceae family. Female strobilus production was correlated with shoot increment, s

The formation of strobili, which are groups of sporangia-bearing sporophylls on shoot apices, terminates the axis growth in the majority of lycopods. Here, we present an interesting developmental aberration in Lycopodium annotinum L. The structure of abnormal strobili was histologically analyzed using the anatomical sections. Additionally, the expression patterns of LAMB1 and LAMB2, which are known to be specific to L. annotinum sporogenous and vegetative tissues, respectively, were comparatively analyzed in normal and abnormal strobili. Histological analyses revealed that the morphological an

Abstract:
Diphasiastrum zeilleri (Rouy) Holub is a hybrid species, with the formula D. complanatum (L.) Holub × D. tristachyum (Pursh) Holub. A high variability of D. zeilleri is due to environmental conditions (light and shadow ecological forms) and probably to introgressive hybridization with the parental species. Intermediate forms between D. zeilleri, D. complanatum and D. tristachyum are quite rare, that allows to treat the three taxa as separate species. D. zeilleri is missing in subarctic regions of Europe and North America, and some degree of its resemblance with D. complanatum subsp. montellii

Abstract:
Recent phylogenetic reconstructions suggest that axially condensed flower-like structures evolved iteratively in seed plants from either simple or compound strobili. The simple-strobilus model of flower evolution, widely applied to the angiosperm flower, interprets the inflorescence as a compound strobilus. The conifer cone and the gnetalean ‘flower’ are commonly interpreted as having evolved from a compound strobilus by extreme condensation and (at least in the case of male conifer cones) elimination of some structures present in the presumed ancestral compound strobilus. These two hypotheses

Abstract:
Adult tapeworms, known as cestodes, reside in the small intestine where they feed off the host’s food. They are attached to the intestinal wall by a structure called the scolex, which is connected to a chain of segments known as proglottids that make up the strobila. Each proglottid contains both male and female reproductive systems and are categorized as immature, mature, or gravid based on their stage of development. Gravid proglottids are found at the end of the strobila and contain a fully developed uterus filled with eggs, which is often used for identification purposes. The eggs and the

Abstract:
Adult tapeworms maintain anchorage to the host small-gut mucosa by means the scolex, a holdfast structure. The rest of the body forms the strobila and consists of a chain of flattened proglottids, which proliferate just behind the scolex. The life cycle then includes larval stages in one or more intermediate hosts. Many species of tapeworm, all zoonoses, infect humans as adult worms or larval stages. Serious disease can result when larval stages occur accidentally in humans, whereas infections by the adult stages often cause little harm. Two groups of cestode infect humans: the Cyclophyllidea
