Cytokinins: Determinants of Sink Storage Ability
نویسندگان
چکیده
A new study demonstrates that storage organ formation can be induced in the axillary meristem of non-tuberizing plants by ectopic expression of the cytokinin biosynthetic gene LONELY GUY (LOG1).

Cytokinins and Expression of SWEET, SUT, CWINV and AAP Genes Increase as Pea Seeds Germinate
Transporter genes and cytokinins are key targets for crop improvement. These genes are active during the development of the seed and its establishment as a strong sink. However, during germination, the seed transitions to being a source for the developing root and shoot. To determine if the sucrose transporter (SUT), amino acid permease (AAP), Sugar Will Eventually be Exported Transporter (SWEE...
متن کاملSink regulation of photosynthesis.
The concept that photosynthetic flux is influenced by the accumulation of photo-assimilate persisted for 100 years before receiving any strong experimental support. Precise analysis of the mechanisms of photosynthetic responses to sink activity required the development of a battery of appropriate molecular techniques and has benefited from contemporary interest in the effects of elevated CO2 on...

Making an increase in the yield of agricultural plants including barely is considered as the main challenge for researchers in agriculture related sciences. Water-soluble carbohydrates transport and source–sink relations have a significant effect on the grain yield. This study was carried out in order to examine genotypic variation of storage and remobilization ability of carbohydrates in eight...
متن کاملPlant development regulated by cytokinin sinks.
Morphogenetic signals control the patterning of multicellular organisms. Cytokinins are mobile signals that are perceived by subsets of plant cells. We found that the responses to cytokinin signaling during Arabidopsis development are constrained by the transporter PURINE PERMEASE 14 (PUP14). In our experiments, the expression of PUP14 was inversely correlated to the cytokinin signaling readout...
متن کاملCytokinins and Their Possible Role in Seed Size and Seed Mass Determination in Maize
One of the richest sources of CKs in various plants species are developing seeds. In fact, zeatin, a major natural CK, was first discovered in developing seeds of maize (Letham, 1963). Not surprisingly, developing seeds of maize, rice and Lupinus albus have played a major role in CK research (reviewed in Emery & Atkins, 2005). A major focus of these studies has been on the possible role of CKs ...
