At stand level, carbon translocation in tree stems has to match canopy photosynthesis and carbohydrate requirements to sustain growth and the physiological activities of belowground sinks. This study applied the Hagen-Poiseuille equation to the pressure-flow hypothesis to estimate phloem carbon
The family Cupressaceae is a relevant source of allergens that causes winter respiratory allergies. Cloning and sequencing the major antigen of Cupressus arizonica is important for a better diagnosis and treatment of sensitized patients. To obtain a full-length complementary DNA for Cup a 1, the
