Define Bundle sheath cell. Bundle sheath cell synonyms, Bundle sheath cell pronunciation, Bundle sheath cell translation, English dictionary definition of Bundle sheath cell. n. A strand of primary conductive plant tissue consisting chiefly of xylem and
By employing the one-step enzymic digestion of maize leaf tissues, mesophyll protoplasts and bundle sheath strands were separated without cross-contamination. Ribulose-1,5-bisphosphate (RuP2 carboxylase and NADP-malic enzyme were found to be exclusively localized in the bundle sheath cells, whereas ph...
To isolate cDNAs for the proteins functioning specifically in MC and BSC, we carried out differential screening and isolated a number of MC-specific- and bundle sheath strands (BSS)-specific clones. During the course of analysis of these clones, we found a phosphoenolpyruvate carboxykinase (PCK) ...
In the extracts from C(4) species there were 7- to 10-fold reciprocal changes in specific activities of ribulose-1, 5-diphosphate carboxylase and phosphoenolpyruvate carboxylase. No such changes occurred in...关键词: plant physiology, plant biochemistry, field crops ...
we identifiedcis-elements and transcription factors driving expression in bundle sheath strands. Upstream of the bundle sheath preferentially expressedMYB76gene, we identified a region necessary and sufficient for expression containing twocis-elements associated with the MYC and MYB families of transcription...

The C4grass Arundinella hirta is characterized by unusual leaf blade anatomy: veins are widely spaced and files of bundle-sheath-like cells, the distinctive cells, form longitudinal strands that are not associated with vascular tissue While distinctive cells (DCs) appear to function like bundle ...
PEPCK activity and protein were enriched in extracts from bundle-sheath (BS) strands compared with whole-leaf extracts. Decarboxylation of [4- 14 C]aspartate (Asp) by BS strands was dependent on the presence of 2-oxoglutarate and Mn 2+ , was stimulated by ATP, was inhibited by the PEPCK-...
