Title: Innovations by Carolyn V Carpenter

Introduction

Carolyn V Carpenter is an accomplished inventor based in Normandy Park, WA (US). She has made significant contributions to the field of conifer embryo research, holding 2 patents that focus on methods for determining the maturity of conifer embryos.

Latest Patents

Her latest patents include a "Method of determining conifer embryo maturity using sugar alcohol content." This invention relates to the understanding of sugar alcohols as indicators of biochemical maturity in pine zygotic and somatic embryos. It has been discovered that loblolly pine zygotic embryos exhibit a progression of different sugar alcohols as they approach biochemical maturity. Pinitol is the first sugar alcohol to appear in abundance, followed by D-chiro-inositol, and finally by fagopyritol B1. The analysis of these sugar alcohols can assist in determining the optimal time to harvest cones from seed orchards and can guide the formulation of more effective culture media for the propagation of somatic embryos through tissue culture.

Another significant patent is the "Method for determining maturity of conifer somatic embryos." This invention focuses on measuring sucrose series oligosaccharides, particularly sucrose, raffinose, and stachyose, along with dehydrin group proteins in conifer somatic embryos. This measurement serves as an indicator of their biochemical maturity and readiness to germinate. The findings are particularly useful for evaluating the effectiveness of culture media used in developing the cotyledonary embryo stage. Somatic embryos with elevated levels of oligosaccharides have shown improved germination, especially in the genus Pinus.
