Chitinase, beta-1,3-glucanase, osmotin, and extensin are expressed in tobacco explants during flower formation.
Sequence analysis of five gene families that were isolated from tobacco thin cell layer explants initiating floral development [Meeks-Wagner et al. (1989). Plant Cell 1, 25-35] showed that two encodeExpand

Modifications of Mitochondrial DNA Cause Changes in Floral Development in Homeotic-like Mutants of Tobacco.
To investigate the influence of mitochondrial genes on stamen development of higher plants, protoplasts from three different, male-sterile tobacco cultivars were fused. The fused cells were culturedExpand

Characterization of a virescent chloroplast mutant of tobacco.
Virescent mutations produce plants in which young leaves have reduced chlorophyll levels but accumulate nearly normal amounts of chlorophyll as they age; they are predominantly nuclear mutations. WeExpand

Mitochondrial involvement in petal and stamen development studied by sexual and somatic hybridization of Nicotiana species
Abstract The interspecific origin, frequency of occurrence, and variation in phenotype of cytoplasmic male-sterile cultivars of Nicotiana tabacum are reviewed in order to provide a framework forExpand

NITROGEN FIXATION BY MEMBERS OF THE STICTACEAE (LICHENES) OF NEW ZEALAND
SUMMARY Forty-four species of New Zealand lichens, including 22 species of Pseudocyphellaria and seven of Sticta, were assayed for nitrogenase activity by acetylene reduction. Nitiogen fixation wasExpand

The Phenotype of a Virescent Chloroplast Mutation in Tobacco Is Associated with the Absence of a 37.5 kD Thylakoid Polypeptide.
The Vir-c mutation is a virescent chloroplast mutation found in a line of plants derived from protoplast fusions between a Nicotina tabacum line and a line containing N. tabacum nuclei with NicotianaExpand

POLYRIBOSOMES AND CISTERNAL ACCUMULATIONS IN ROOT CELLS OF RADISH
The zone of root hair formation of seedling radish roots, Raphanus sativus L., was studied by phase-contrast and electron microscopy. Localized dilations of the endoplasmic reticulum, which containedExpand

SPECIFICITY IN THE GUNNERA‐NOSTOC ENDOSYMBIOSIS
Summary The cyanobacterium, Nostoc, and the angiosperm, Gunnera, form a symbiotic association in which glandular cells host an intracellular population of heterocystous Nostoc cells. Symbiotic andExpand
