Sporogenesis and development of gametophytes in an endangered plant, Tetracentron sinense Oliv
Biological Research, 2012 The sporogenesis and development of gametophytes in Tetracentron sinense Oliv. were studied with light microscopy. The anther has four microsporangia; its primary anther wall consists of an epidermis, an endothecium, one or two middle layers and one ...

Marine heatwave and keystone predator loss drive broad-scale decline and hinder recovery of a rocky intertidal kelp. [PDF]
Ecol ApplAbstract Human activities are increasingly driving the co‐occurrence of multiple ecological stressors, resulting in interactive and cumulative impacts that can reshape ecosystem dynamics and accelerate population declines of climate‐sensitive species. Here, we use over two decades of rocky intertidal monitoring data from 17 sites spanning over 1200 km ...

Sporogenesis and Pollen Grain Formation
, 1981 Pollen grains and the spores of nonseed vascular plants1 develop from diploid somatic cells in a largely identical way. Ultimately, the cells are characterized by a highly ordered cell wall, the so-called sporoderm (Figs. 1 and 2). Both the chemical and the principal ultrastructural features of sporoderms show little Variation in different taxa ...

Effects of Culture Aeration and the C:N Ratio on Propagule Production by Submerged Cultivation of Clonostachys rosea and Its Antifungal Metabolite Profiling. [PDF]
MicrobiologyopenOptimized submerged fermentation of Clonostachys rosea under high aeration enhances production of submerged conidia and microsclerotia. Formulated propagules and antifungal metabolites, including sorbicillinoids, effectively control tomato gray mold, offering a promising strategy for biocontrol product development.
