Retrospective Theses and Dissertations

The entire soybean Sle gene family was cloned and characterized. The five Sle genes (Sle1-5) could be divided into two classes based on sequence identity. Sle1-4 map to 4 different linkage groups. Sle1 and Sle5 are expressed weeks earlier in seed development than Sle2 and Sle3. Sle4 is a pseudogene. Maximal levels of Sle mRNA accumulate in the seeds, before desiccation had occurred, and decline rapidly upon seed imbibition. Desiccation does not induce Sle expression in seeds. Unlike most of its homologs, ABA is not necessary to induce Sle expression in cultured embryos and only moderately increases Sle mRNA levels ...
