Abstract

Exposure of broad bean (Vicia faba L.) plants to 270 +/- 32 and 670 +/- 45 micrograms m 3SO{sub 2} for 1.5 hr daily between 40 and 85 days of their ages resulted in an increase in their transpiration rate, water saturation deficit, phenol content, and peroxidase activity and a decrease in protein content. With the increase in number of exposures of plants to SO{sub 2}, chlorotic and brown, necrotic visible injury signs were also developed in leaves. It was further noted that the magnitude of undesirable biochemical changes, which possibly helped in the formation of new pigment characteristic of necrotic tissue of SO{sub 2}-exposed plants, was not totally dependent on the pollutant concentration.

Nitrogen dioxide and sulfur dioxide interact to injure horticultural and agronomic crops

Journal Article Dunning, J; Tingey, D; Reinert, R - HortScience; (United States)

Six horticultural and agronomic crops were exposed for 4 hours to nitrogen dioxide (NO/sub 2/) and/or sulfur dioxide (SO/sub 2/) in greenhouse exposure chambers. Concentrations of NO/sub 2/ in excess of 200 pphm and concentrations of SO/sub 2/ in excess of 50 pphm were required to cause injury. Plant injury developed when the gases were mixed together in the concentration ranges of 5-25 pphm of both gases. Injury from either NO/sub 2/ or SO/sub 2/ acting alone appeared as a marginal and interveinal bifacial necrosis. The injury produced by the mixture of the two gases developed as chlorotic and necroticmore »« less
A new mechanism for the regulation of stomatal aperture size in intact leaves: Accumulation of mesophyll-derived sucrose in the guard-cell wall of Vicia faba

Journal Article Lu, Ping; Outlaw, Jr, W; Smith, B; ... - Plant Physiology (Bethesda)

At various times after pulse-labeling broad bean (Vicia faba L.) leaflets with {sup 14}CO{sub 2}, whole-leaf pieces and rinsed epidermal peels were harvested and subsequently processed for histochemical analysis. Cells dissected from whole leaf retained apoplastic contents, whereas those from rinsed peels contained only symplastic contents. Sucrose (Suc)-specific radioactivity peaked (111 GBq mol{sup -1}) in palisade cells at 20 min. In contrast, the {sup 14}C content and Suc-specific radioactivity were very low in guard cells for 20 min, implying little CO, incorporation; both then peaked at 40 min. The guard-cell apoplast had a high maximum Suc-specific radioactivity (204 GBq mol{supmore »« less
Effect of sulphur dioxide exposure on chlorophyll content and nitrogenase activity of Vicia faba L. plants

Journal Article Agrawal, S; Agrawal, M - Bulletin of Environmental Contamination and Toxicology; (United States)

The annual average concentrations of SO{sub 2} around Obra thermal power plant and nonpolluted sites in India were reported as 0.06, and 0.007 ppm, respectively. However, daily average concentrations in areas close to the emission source may be as large as 0.34 ppm. Therefore, in the present investigation an attempt has been made to determine the potential effects of such episodic and exceptionally high intermittent concentrations of SO{sub 2} on total chlorophyll content and nitrogenase activity of Vicia faba (broad bean) plants.

Inhibition of loading of sup 14 C assimilate by p-chloromercuribenzenesulfonic acid. [Vicia faba L]

Journal Article Bourquin, S; Bonnemain, J; Delrot, S - Plant Physiology; (USA)

The apoplast of mature leaves excised from broadbean (Vicia faba L.) plants was infiltrated with 2 millimolar p-chloromercuribenzenesulfonic acid (PCMBS) via the transpiration stream, and the ability of the tissues to take up sugars was tested. An infiltration time of 75 minutes was sufficient of obtain a maximal (75%) inhibition of exogenous ({sup 14}C)sucrose (1 millimolar) uptake. This infiltration affected neither CO{sub 2} assimilation nor the transmembrane potential difference of leaf cells but strongly inhibited phloem loading of endogenous ({sup 14}C) assimilates. The study of the symplastic relations between the different cell types of the mature leaf showed that themore »« less

Plant, cell, and molecular mechanisms of abscisic-acid regulation of stomatal apertures. A new mechanism for the regulation of stomatal-aperture size in intact leaves: Accumulation of mesophyll-derived sucrose in the guard-cell wall of Vicia faba L.

Technical Report Lu, P; Outlaw, Jr, W; Smith, B; ...

At various times after pulse labeling Vicia faba L. leaflets with {sup 14}CO{sub 2}, whole-leaf pieces and rinsed epidermal peels were harvested and subsequently processed for histochemical analysis. Cells dissected from whole leaf retained apoplastic contents whereas those from rinsed peels contained only cytoplastic contents. Sucrose specific radioactivity peaked in palisade cells, 111 GBq{center_dot}mol{sup {minus}1}, at 20 min. In contrast, the {sup 14}C content and sucrose specific radioactivity were very low in guard cells for 20 min, implying little CO{sub 2} incorporation; both then peaked at 40 min.
