Reconstruction of the Central Zagros paleo climate and paleo environment
Introduction The study of lake sediments has been widely used in recent decades to identify past climate and environmental changes. Lake basins have significant spatial and temporal patterns and provide valuable evidences of physical and chemical changes. However, in general, the climate of the Holocene period has been more stable and uniform than previous glacial and interglacial periods. How...
متن کاملSedum Acre Embryogenesis: Polyploidization in the Suspensor
Cytological processes of differentiation in the embryo suspensor of Sedum acre L. were compared with the development of the embryo proper. The zygote undergoes an asymmetric division to produce an apical cell and a basal cell, which becomes the basal cell of the suspensor. The mature differentiated suspensor consists of a large haustorial basal cell and 3–4 chalazal cells. The basal cell nucleu...
متن کاملAnalysis of river sediments in the paleo- Meyghan basin
Introduction The territory of central Iran is now affected by the hot and dry climate. But, several evidences, such as the extreme erosion of running waters, huge alluvial fans, wide alluvial terraces, and flood deposits indicate colder and wetter climate in the territory (Ghahroodi Tali, 2011: 3). The rivers belong to the most important parts of the sedimentary basin. In fact, the rivers are...
متن کاملPolyploidization-induced genome variation in triticale.
Polyploidization-induced genome variation in triticale (x Triticosecale Wittmack) was investigated using both AFLP and RFLP analyses. The AFLP analyses were implemented with both EcoRI-MseI (E-M) and PstI-MseI (P-M) primer combinations, which, because of their relative differences in sensitivity to cytosine methylation, primarily amplify repetitive and low-copy sequences, respectively. The resu...
متن کاملScouting Craton's Edge in Paleo-pacific Gondwana
The geology of the ice-covered interior of the East Antarctic shield is completely unknown; inferences about its composition and history are based on extrapolating scant outcrops from the coast inland. Although the shield is clearly composite in nature, a large part of its interior has been represented by a single Precambrian block—termed the Mawson block—that includes the ArcheanMesoproterozoi...
