1. Evidence for Unidirectional Flow through Plasmodesmata

Author:
Christensen, Nynne Meyn; Faulkner, Christine; Oparka, Karl
Source:
Plant physiology 2009 v.150 no.1 pp. 96-104
ISSN:

Subject:
green fluorescent protein; plasmodesmata; sodium azide; mass flow; transgenic plants; trichomes; solutes; gene expression; viruses; Nicotiana tabacum; esters; tobacco; metabolic inhibitors; fluorescein; leaves
Abstract:
... The leaf trichome of tobacco (Nicotiana tabacum) represents a unique secretory structure in which the basal trichome cell is connected to the epidermis by numerous plasmodesmata (PD). Small fluorescent probes microinjected into the basal trichome cell moved apically into distal trichome cells but not into the subtending epidermal cell. In marked contrast, the same probes moved apically into tricho ...

Abstract:
... C₂H₄ is associated with plant defense, but its role during the hypersensitive response (HR) remains largely uncharacterized. C₂H₄ production in tobacco (Nicotiana tabacum) following inoculation with HR-eliciting Pseudomonas syringae pathovars measured by laser photoacoustic detection was biphasic. A first transient rise (C₂H₄-I) occurred 1 to 4 h following inoculation with HR-eliciting, disease-fo ...

Abstract:
... A cDNA encoding a protein with 456 amino acids whose sequence shows considerable similarity to plant acyltransferases was identified among 750 Clarkia breweri flower expressed sequence tags. The cDNA was expressed in Escherichia coli, and the protein produced was shown to encode the enzyme benzoyl-coenzyme A (CoA):benzyl alcohol benzoyl transferase (BEBT). BEBT catalyzes the formation of benzylben ...

Abstract:
... The anaphase promoting complex or cyclosome is the ubiquitin-ligase that targets destruction box-containing proteins for proteolysis during the cell cycle. Anaphase promoting complex or cyclosome and its activator (the fizzy and fizzy-related) proteins work together with ubiquitin-conjugating enzymes (UBCs) (E2s). One class of E2s (called E2-C) seems specifically involved in cyclin B1 degradation. ...

5. Tobacco O-methyltransferases involved in phenylpropanoid metabolism. The different caffeoyl-coenzyme A/5-hydroxyferuloyl-coenzyme A 3/5-O-methyltransferase and caffeic acid/5-O-hydroxyferulic acid 3/5-O-methyltransferase classes have distinct substrate specificities and expression patterns

Nicotiana tabacum; transferases; phenylpropanoids; biosynthesis; gene expression; methylation; Tobacco mosaic virus; leaves; isozymes; Escherichia coli; esters; biochemical pathways; lignin
Abstract:
... The biosynthesis of lignin monomers involves two methylation steps catalyzed by orthodiphenol-O-methyltransferases: caffeic acid/5-hydroxyferulic acid 3/5-O-methyltransferases (COMTs) and caffeoyl-coenzyme A (CoA)/5-hydroxyferuloyl-CoA 3/5-O-methyltransferases (CCoAOMTs). Two COMT classes (I and II) were already known to occur in tobacco (Nicotiana tabacum) and three distinct CCoAOMT classes have ...

Abstract:
... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

Abstract:
... Polygalacturonate 4-alpha-galacturonosyltransferase (EC 2.4.1.43) activity has been identified in microsomal membranes isolated from tobacco (Nicotiana tabacum L. cv Samsun) cell-suspension cultures. Incubation of UDP-[14C]galacturonic acid with tobacco membranes results in a time-dependent incorporation of [14C]galacturonic acid into a chloroform-methanol-precipitable and 65% ethanol-insoluble pr ...

Abstract:
... Transgenic tobacco (Nicotiana tabacum L.) plants carrying a fusion between the nopaline synthase (nos) promoter and chloramphenicol acetyltransferase (CAT) reporter gene (cat) were tested for their response to treatment with H2O2. The nos promoter-driven CAT activity increased significantly by addition of H2O2, reaching the maximum level at 15 mM. Kinetic analysis for CAT activity showed that indu ...
