Abstract: The present invention relates to methods for modulating glucosinolate production in plants, specifically by modulating CYP83A1 expression. The present invention also relates to transgenic plants that over-express and underexpress CYP83A1.

Abstract: The present invention relates to methods for modulating auxin and glucosinolate production in plants, specifically by modulating CYP83B1 expression. The present invention also relates to transgenic plants that overexpress and underexpress CYP83B1.

Abstract: Methods are described herein for producing hybrid seed using male-sterile plants wherein reproductive function is restored by treatment of mutant plants with selected plant hormones. Plants comprising mutations in the allene oxide synthase gene are functionally male-sterile and are useful for the production of hybrid seed, wherein fertility is restored in the plants by treatment with jasmonic acid. Hybrid seed production is simplified and improved by this invention. The present invention also includes plants comprising mutations in genes affecting allene oxide synthase and/or hydroperoxide lyase.

Abstract: Methods are described herein for producing male-sterile plants by underexpressing the allene oxide synthase (CYP74A) gene. Fertility is restored in the plants by treatment with jasmonic acid. Hybrid seed production is simplified and improved by this invention. The present invention also includes plants transformed with an allene oxide synthase coding sequence.

Abstract: An eighteen amino acid neuropeptide isolated from brain complexes of adult female cockroach, Diploptera punctata, is identified as an allatostatin because it inhibits the biosynthesis of juvenile growth hormone in cockroach corpora allata. Primary structure of the isolated allatostatin is Al a-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro-Val-Tyr-Asn-Phe-Gly-Leu-NH.s ub.2. A synthetic peptide of this sequence and three synthetic peptides with truncated sequences conserving the amidated carboxyl portion of the native sequence have allatostatin activity. Certain derivatives of the peptides also have allatostatin activity including compounds having the sequence: X-Val-Tyr-Asn-Phe-Gly-Leu-NH.sub.2, in which X is Leu-Arg, Leu-Pro, Arg-Leu-Pro-, Ala-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro, acetyl-Ala-Tyr-Ser-Tyr-Val-Ser-Glu-Tyr-Lys-Arg-Leu-Pro, or acetyl-Arg-Leu-Pro. These peptides have the potential for regulating the growth of certain insects, and may be useful in the area of insect control.
