French bean ( Phaseolus vulgaris L.) is an important vegetable known as green beans, which is widely cultivated during winter in the subtropics and early spring to fall in temperate zones throughout the world. In India, it is grown in the

Physiological differences between cttokinins are well documented. An explanation for these differences is that cytokinins differentially regulate genes. Gene response has been analyzed in cell culture and organized tissue of Phaseolus vulgaris L. cv. Great Northern. Two novel cDNAs, L-221 and L-22, have been identified that are cytokinin responsive. In leaf tissue L-221 was repressed by zeatin, benzyladenine and thidiazuron at 50 μM. In suspension cell culture mRNA abundance of L-221 remained constant regardless of cytokinin treatment. By contrast, the abundance of L-22 mRNA was increased differentially by treatment with each of the 3 cytokinins in leaf tissue. Suspension cells analyzed for expression of L-22 after cytokinin treatment also showed differential gene expression. S-1 Nuclease Protection Assays revealed that gene expression is a transient phenomenon dependent upon the time of cytokinin application and cytokinin concentration. Callus bioassays showed that dihydrozeatin and O-glucosylzeatin gave greater responses than the co-application of zeatin and dihydrozeatin or zeatin and O-glucosylzeatin. The conjugate and the reduction derivative also gave greater responses than zeatin alone. Effects of dihydrozeatin and O-glucosylzeatin on gene expression will be reported.

Abstract

In the article “Effects of Water Stress on Pollen of Phaseolus vulgaris L.”, by Xiu Ying Shen and Barbara D. Webster (J. Amer. Soc. Hort. Sci. 111:807–810, September 1986), on p. 808, the last sentence before Results and Discussion should read: “The term microspore refers to the uninucleate structures released from tetrads after meiosis. The term pollen grain refers to the above structures after mitosis of the microspore nucleus and formation of the vegetative (tube) and generative cells.”

Abstract

Ozone (O3) is the most damaging air pollutant affecting agricultural crops in the United States and bean is one of the most O3-sensitive crop species. More than 2000 plant introductions of Phaseolus vulgaris L. were evaluated for sensitivity to O3 by exposing bean plants to 0.6 ppm O3 for 2 hours under controlled environmental conditions; 54 insensitive and 67 highly sensitive plant introductions were identified based on foliar injury symptoms.
