Sporophyte morphology and gametophyte development of the fern Blechnum sprucei (Pteridophyta: Blechnaceae).
The fern Blechnum sprucei grows in Mesoamerica (Costa Rica) and South America, from Colombia to Bolivia, SE and centre of Brazil, Paraguay and Argentina. It is a distinctive, somewhat vulnerable, mostly orophilous species. Fresh and dry herbarium material was used for this study. Herbarium material for anatomical studies comes from CTES, BA, LP, MA, SI and UC (Holmgren et al. 1990). Selected re...
متن کاملSporophyte and gametophyte generations differ in their thermotolerance response in the moss Microbryum.
BACKGROUND AND AIMS Actively growing post-embryonic sporophytes of desert mosses are restricted to the cooler, wetter months. However, most desert mosses have perennial gametophytes. It is hypothesized that these life history patterns are due in part to a reduced thermotolerance for sporophytes relative to gametophytes. METHODS Gametophytes with attached embryonic sporophytes of Microbryum st...
متن کاملWall 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 کاملIdentification and Characterization of TALE Homeobox Genes in the Endangered Fern Vandenboschia speciosa
We report and discuss the results of a quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis of the expression patterns of seven three amino acid loop extension (TALE) homeobox genes (four KNOTTED-like homeobox (KNOX) and three BEL1-like homeobox (BELL) genes) identified after next generation sequencing (NGS) and assembly of the sporophyte and gametophyte transcriptome...
متن کاملThe WUSCHEL‐RELATED HOMEOBOX 3 gene PaWOX3 regulates lateral organ formation in Norway spruce
In angiosperms, WUSCHEL-RELATED HOMEOBOX 3 (WOX3) genes are required for the recruitment of founder cells from the lateral domains of shoot meristems that form lateral regions of leaves. However, the regulation of the formation of lateral organs in gymnosperms remains unknown. By using somatic embryos of Norway spruce (Picea abies) we have studied the expression and function of PaWOX3 during em...
