Effects of plant species richness on 13C assimilate partitioning in artificial grasslands of different established ages
Artificial grasslands play a role in carbon storage on the Qinghai-Tibetan Plateau. The artificial grasslands exhibit decreased proportions of graminate and increased species richness with age. However, the effect of the graminate proportions and species richness on ecosystem C stocks in artificial grasslands have not been elucidated. We conducted an in situ13C pulse-labeling experiment in Augu...
متن کاملSucrose is a signal molecule in assimilate partitioning.
The proton-sucrose symporter mediates the key transport step in the resource distribution system that allows many plants to function as multicellular organisms. In the results reported here, we identify sucrose as a signaling molecule in a previously undescribed signal-transduction pathway that regulates the symporter. Sucrose symporter activity declined in plasma membrane vesicles isolated fro...
متن کاملAssimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: photosynthesis and carbon partitioning throughout the photoperiod
(Assimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: photosynthesis and carbon partitioning throughout the photoperiod). Lamium album accumulates starch, sucrose and raffinose-family oligosaccharides (RFO) as the major products of photosynthesis. These products were measured in leaves throughout a sixteen-hour photoperiod and under various irradiance conditions. The...
متن کاملThe role of branch architecture in assimilate production and partitioning: the example of apple (Malus domestica)
Understanding the role of branch architecture in carbon production and allocation is essential to gain more insight into the complex process of assimilate partitioning in fruit trees. This mini review reports on the current knowledge of the role of branch architecture in carbohydrate production and partitioning in apple. The first-order carrier branch of apple illustrates the complexity of bran...
متن کاملExpression of a putative grapevine hexose transporter in tobacco alters morphogenesis and assimilate partitioning.
Tobacco plants were transformed by leaf disc regeneration with the VvHT1 (Vitis vinifera hexose transporter 1) cDNA under the control of the constitutive CaMV 35S promoter in a sense or antisense orientation. Among the 20 sense plants and 10 antisense plants obtained, two sense plants showed a mutant phenotype when grown in vitro, with stunted growth and an increase in the (leaves+stem)/roots d...
