Abscisic acid (ABA)-mediated gene expression is a critical component of plant responses to this important hormone, which affects plant growth, development, and responses to environmental stresses. Plant responses to ABA are mediated by a number of factors including PKABA1, an ABA induced protein kinase involved in ABA-suppressed gene expression in cereal grains, and TaWD40, which has previously been shown to physically interact with PKABA1. A full-length 1.9 kb TaWD40 cDNA, CK210682, was sequenced as part of this project. Based on the deduced protein sequence, it is thought that TaWD40 may belong to the family of E3 ubiquitin ligases, possibly targeting PKABA1 for destruction. Construction of expression plasmids for overproduction of the TaWD40 polypeptide in E. coli is currently underway. The TaWD40 cDNA has been successfully amplified from the source plasmid and inserted into an intermediate plasmid, pCR2.1. The TaWD40 cDNA is currently being cloned from the pCR2.1 intermediate plasmid into two different expression vectors, pRSET-A and pMAL-c2x, for future protein production and purification.

“Conservation Lands” include both public and private lands that are devoted to the protection of wildlife and natural resources. “Listed Species” include federally and state endangered and threatened animals that are in danger of extermination in the state of Maine. The purpose of this study is to determine how well conservation lands are protecting the habitats of listed species. GAP data was used for 13 terrestrial vertebrate species indicating the presence or absence of suitable habitats. This data was compiled in GIS, generating a layer showing the number of listed species an area is suitable for. The areas that were suitable for at least one habitat were compared to answer three questions: (1) Is there is a difference between the presence and absence of listed species on protected lands and lands that are not protected? (2) Is there is a difference between the presence and absence of listed species on public lands managed by the state and the federal government and private land? (3) Is there is a difference between the presence and absence of listed species on lands protected under easements and lands that are protected fee simple? We found significant differences between all three categories. Conservation lands, private lands, and lands held under easement protect the habitat of listed species most effectively. We believe that this is due to the large number of private land trusts in the state of Maine and the effective management strategies of state lands.
