Biomarkers in the fossils from the Miocene-aged Chukurovo lignite, Bulgaria: sesqui- and diterpenoids
The attention is focused on the “Chukurovo” lignites of the Sofia coal-bearing province. The coal sediments are of Neogene age: petrological studies have indicated a Badenian-Sarmatian age, while the paleobotanical interpretations have indicated the Karpatian-Badenian, respectively Early-Middle Miocene boundary. Fossilized trees are common in the Chukurovo lignites, as well as petrified wood ti...
متن کاملMolecular regulation of seed and fruit set.
Seed and fruit set are established during and soon after fertilization and determine seed and fruit number, their final size and, hence, yield potential. These processes are highly sensitive to biotic and abiotic stresses, which often lead to seed and fruit abortion. Here, we review the regulation of assimilate partitioning, including the potential roles of recently identified sucrose efflux tr...
متن کاملThe Importance of Fossils in Elucidating Seed Plant Phylogeny and Macroevolution
Doyle, J.A. and Donoghue, M.J., 1987. The importance of fossils in elucidating seed plant phylogeny and macroevolution. Rev. Palaeobot. Palynol., 50: 63--95. In order to gain insights on the controversial question of the value of fossils in understanding phylogeny and macroevolution, we used numerical parsimony methods to analyze a data set amassed for a cladistic study of living and fossil see...
متن کاملTrematolobelia: Seed Dispersal; Anatomy of Fruit and Seeds
THE ENDEMIC HAWAIIAN GENUS Trematolobelia (Lobeliaceae, or Campanulaceae, subfamily Lobelioideae) was erected on the basis of its distinctive fruit. This fruit has a seed-dispersal mechanism unique in the family. Assertions have been made by some workers that holes in the fruit wall are the work of insects, and are not related to the dispersal mechanism. This contention has been adequately disp...
متن کاملHormone and seed-specific regulation of pea fruit growth.
Growth of young pea (Pisum sativum) fruit (pericarp) requires developing seeds or, in the absence of seeds, treatment with gibberellin (GA) or auxin (4-chloroindole-3-acetic acid). This study examined the role of seeds and hormones in the regulation of cell division and elongation in early pea fruit development. Profiling histone H2A and gamma-tonoplast intrinsic protein (TIP) gene expression d...
