Wall Projections in the Sporophyte and Gametophyte of Sphaerocarpos
The nutrition of the sporophyte in Sphaerocarpos and liverworts in general has long been controversial . It has not yet been determined whether the chloroplasts in the sporophyte capsule do, in fact, photosynthesize or whether the carbohydrates stored as starch are translocated to the sporophyte from the gametophyte which is known to be photosynthetic and to which the sporophyte remains attache...
متن کاملTranscriptomes of the Anther Sporophyte: Availability and Uses
An anther includes sporophytic tissues of three outer cell layers and an innermost layer, the tapetum, which encloses a locule where the gametophytic microspores mature to become pollen. The sporophytic tissues also comprise some vascular cells and specialized cells of the stomium aligning the long anther axis for anther dehiscence. Studies of the anther sporophytic cells, especially the tapetu...

متن کاملEctomycorrhizal sporophore distributions in a southeastern Appalachian mixed hardwood/conifer forest with thickets of Rhododendron maximum.
Sporophore abundance of putatively ectomycorrhizal fungi was compared in a mature mixed hardwood/conifer forest inside of (+) versus outside of (-) Rhododendron maximum thickets (RmT). Experimental blocks (1/4 ha) were established inside of (3) and outside of (3) RmT at the Coweeta Hydrologic Laboratory in Macon County, North Carolina, USA. Litter and organic layer substrates were removed, comp...
متن کاملFertile sporophore production of Typhula phacorrhiza in the field is related to temperatures near freezing.
Two field tests and one lab test were conducted to examine the environmental factors affecting sporophore production in Typhula phacorrhiza and to compare these results with those documented for T. ishikariensis and T. incarnata. In the 2001 lab test where lighting, soil moisture, and soil-sand media were tested in 50 mL screw-cap tubes incubated at 4 degrees C, the limiting factor for Typhula ...
