Abstract:
... We investigated the role of actin microfilaments in nonhost resistance of higher plants. Here we present several lines of evidence to indicate that microfilaments are indeed involved in blocking fungal penetration of nonhost plants. Erysiphe pisi, a pathogen of pea, normally fails to penetrate into nonhost plants such as barley, wheat, cucumber and tobacco. When tissues of these nonhost plants wer ...

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 ...

3. Recovery of Fertilizer Nitrogen Applied to Burley Tobacco

Subject:
Nicotiana tabacum; nitrogen fertilizers; measurement; isotope labeling; residual effects; drilling; cover crops; Triticum aestivum; Festuca arundinacea; nutrient uptake; crop yield; application rate; application timing; Kentucky
Abstract:
... The high cash value of burley tobacco (Nicotiana tabacum L.) may lead to ineffective excess fertilization Of the crop. The effects of N management on fertilizer N use efficiency by hurley tobacco and recovery of residual fertilizer N by a winter cover crop were determined. Tobacco was grown in 1993 at two locations with 0 to 336 kg N ha⁻¹ broadcast applied before transplanting or 168 kg N ha⁻¹ sid ...

4. Trafficking of wheat gluten proteins in transgenic tobacco plants: gamma-gliadin does not contain an endoplasmic reticulum-retention signal

Author:
Napier, J.A.; Richard, G.; Turner, M.F.P.; Shewry, P.R.

Triticum aestivum; gliadin; signal peptide; transgenic plants; Nicotiana tabacum; cell membranes; endoplasmic reticulum; vacuoles; leaves; protein transport; protoplasts; cell wall components
Abstract:
... Wild-type and mutated forms of the wheat (Triticum aestivum L.) storage protein gamma-gliadin were expressed in transgenic tobacco (Nicotiana tabacum L. cv. NVS) under the control of the 35S cauliflower mosaic virus (CaMV) promoter in order to determine what, if any, endogenous targeting signals are present in the wild-type gamma-gliadin protein. The mutant forms of the protein were modified by th ...
