Auxin-Regulated Gene Expression, Tom J. Guilfoyle

Journal of the Iowa Academy of Science: JIAS

A number of cDNA clones to independent mRNAs that increase in amount after brief exposure to auxins have been isolated. From soybean, sequenced, and characterized. Increases in mRNA abundance can be detected as early as 2.5 minutes after auxin application to excised elongating regions of soybean hypocotyls. Increased transcription rates on the genes which encode the auxin-responsive mRNAs account, at least partly, for the accumulation of mRNAs. A variety of auxins induce the accumulation of the mRNAs, but other plant hormones have no effect on the mRNA abundance. Some of the genes which encode the mRNAs are clustered in the …

Effect Of Irradiation And Dielectric Heating On Soybean Ultrastructure, Trypsin Inhibitor, And Lipoxygenase Activities, E. Kovacs, N. D. Lam, J. Beczner, I. Kiss

Food Structure

Scanning electron microscopy ( SEM) was used to observe the protein bodies of soybeans after irradiation (0 - 10 kGy dose range) , dielectric heating and storage . Microbiological changes , lip oxygenase and trypsin inhibit or activities and biological value were also studied after different treatments and storaee . There were no differences in the ultrastructure of control and irradiated ( 3, 6 and 10 kGy) soybeans immediately after irradiation . The effect of storage depended on whether whole or milled soybeans had been stored . There was no direct effect of dielectric he ating on soybeans ultrastruc ture …

Ec91-136 Managing Deficient Soybean Stands, Gary E. Pepper, David B. Willmot

University of Nebraska-Lincoln Extension: Historical Materials

Soybean producers whose crops suffer poor stand emergencemay wonder whether or not replanting presents a viable economic alternative. Sometimes growers elect to replant deficient stands, but doing so can add considerable expense to their operations through the costs for seed, tillage operations, and perhaps even herbicides. The grower's economic risk is compounded by the possible loss in potential yield due to late seeding, which eventually leads to a reduction in net profit. Making the decision to either replant or stick with a somewhat deficient field is difficult.

The information in this circular is intended to help growers decide which course …
