Turning point for early human diets occurred 3.5 million years ago
Plants can be divided into three categories based on their method of photosynthesis: C3, C4, and CAM. C3 plants (trees ... suggests an expansion in the dietary adaptation of the species," said Alemseged. The authors of this week's papers also sampled ...
‘CO₂ is food for plants!’ What will higher emissions mean for crop productivity?
At the same time it is the source of carbon for plants on Earth. Laboratory studies have shown that having more CO₂ in the air will increase the rate of photosynthesis and growth for most temperate plants, if they have enough water and nutrients.
Converting C3 plant ( rice ) into C4 ?
s it was established that cultured tissues of C3 plants have activity of PEPcase enzyme. We refrained in calling it a "C4" callus. The callus tissue from Maize in dedifferentiated stage also showed activity of both the enzymes RuBISCO and PEPcase depending ...
Genes may travel from plant to plant to fuel evolution
The genes were incorporated into the metabolic cycle of the recipient plant, aiding adaptation ... the ppc enzymes used in C4 photosynthesis would be closely related to the non-photosynthetic genes from closely related C3 plants, given their common ...
The Paradox of the Nutcracker Man
Researchers look for two main plant groups: C3 plants are trees, fruits and herbaceous plants that grow in environments with cooler seasons while C4 plants are the grasses ... Instead of being adaptations to cracking open hard objects, the species ...
