Changes in Nucleic Acid Fractions of Seed Components of Red Pine (Pinus resinosa Ait.) during Germination.
Changes in nucleic acid fractions of Pinus resinosa during seed germination were studied. At various stages of seed germination, embryos and megagametophytes were surgically separated and nucleic acids were extracted separately by a phenol-method. Total nucleic acids were fractionated on single-layer methylated albumin kieselguhr (MAK) columns. Total nucleic acids in embryos increased significa...

متن کاملSeed Dispersal: Same Gene, Different Organs
A single nucleotide change in a conserved promoter element is responsible for both human-selected retention of rice grains on pedicels and for naturally selected differences in dehiscence-associated fruit structures in mustards.
متن کاملGermination in Seed Species Ingested by Opossums: Implications for Seed Dispersal and Forest Conservation
Seed germination in plant species consumed by opossums, genus Didelphis, was investigated in southern Brazil, in order to improve knowledge of the strategies of zoochorous plants in the Neotropics. Seeds were obtained from opossum feces. Thirteen of the most frequent species in the diet of local opossums were tested for germination rates and germination responses under different qualities (red/...
