متن کاملDNA barcoding reveals a new record of Potamogeton distinctus (Potamogetonaceae) and its natural hybrids, Potamogeton distinctus × Potamogeton nodosus and Potamogeton distinctus × Potamogeton wrightii (Potamogeton ×malainoides) from Myanmar
Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...

متن کاملInvestigating the molecular basis for heterophylly in the aquatic plant Potamogeton octandrus (Potamogetonaceae) with comparative transcriptomics
Many plant species exhibit different leaf morphologies within a single plant, or heterophylly. The molecular mechanisms regulating this phenomenon, however, have remained elusive. In this study, the transcriptomes of submerged and floating leaves of an aquatic heterophyllous plant, Potamogeton octandrus Poir, at different stages of development, were sequenced using high-throughput sequencing (R...
متن کاملEl género real de los grupos C 2 m × Dn
Todo grupo finito G actúa como grupo de automorfismos de diversas superficies de Klein con borde. Al menor de los géneros algebraicos de estas superficies se le llama género real ρ(G) del grupo G. Se conocen todos los grupos con 0 ≤ ρ(G) ≤ 8, aśı como el género real para varias familias de grupos. En este trabajo calculamos el género real de los grupos G = C2m × Dn, en función de los números m ...
