I. FOREWORD

The working research information here is shared with the understanding that each item is unpublished and is not to be cited in publications without specific consent of the authors. By sharing our research information here, we contribute to the advancement of biology and to the power of shared technical knowledge.

 Information here is in the form of "notes" and is not "published" in the sense of a refereed journal. In event a policy statement should be needed, the following suggested guidelines may ensure against misunderstanding of our Newsletter:
1) In publications, whenever permitted, refer to MNL notes in the text, rather than in the bibliography. Specify "unpublished data", or "personal communication" (i.e., with the colleague's consent). The volume and page numbers might be given, as an aid to the reader.
2) When preparing your MNL notes, emphasize brief technical notes, updates, mutants, mapping data, and the like. Avoid presenting comprehensive material and analyses that are better directed to formal publication.
3) Never refer to MNL notes as "published".
4) If challenged, forward these comments as a statement of the purpose, intent, and policy of the cooperators who contribute to this Newsletter.

More and more cooperators supply notes, tables and figures in electronic form, and this greatly facilitates the editing and compiling.

 Gifts to the Endowment Fund for support of the Newsletter now total over $80,000. Please see the listing, in the front of this issue, of donors whose generosity has made this total grow. We are all grateful for the support of our colleagues and of organizations with which we have common interests. The continuity and support necessary for collecting genetic and molecular information, evaluating it, and preparing gene lists, maps, and similar syntheses, however, is made possible only by sustained and ongoing encouragement of this work within the Agricultural Research Service, USDA, specifically as part of my regular research project and most recently as part of the Plant Genome Initiative project for development of a database prototype for maize.

 A warm acknowledgment for help, advice and ideas during the past year is given to my colleagues, Gerry Neuffer, Mary Polacco, Georgia Davis, Pat Byrne, Shiaoman Chao, Larry Darrah, Jim Birchler, Karen Cone, Kathy Newton, Jack Beckett, Guri Johal, Mike McMullen, Don Miles, and John Walker. Their advice and encouragement, not to mention tolerance, is greatly appreciated.

Shirley Kowalewski skillfully edited and nurtured the contents from rough into fine form, surprised the word-processor by getting it to do what was needed, structured the year's literature, and gave creative advice at critical moments. Mary Ann Steyaert booked addresses and subscriptions through the year, carried out literature searching and verifications with efficiency and accuracy, and artfully prepared the mockup. Denis Hancock steadily and enthusiastically enhanced our computer efficiency to a higher art. Kudos for vigilance and communications are given to Lou Butler and Evelyn Bendbow, for their contributions of accuracy to the gene list and other places. At University Printing Services, Yvonne Ball and the printshop staff again efficiently ensured the job was done promptly and well.

 For submission of notes for the next issue (Number 68, 1994), please see details inside the back cover.

 If you wish to subscribe to this Newsletter please use the form in the back of this issue. Gifts to the Endowment Fund, toward our goal of $100,000, will be very much appreciated.

The next Maize Genetics Conference is scheduled at Pheasant Run, March 24-27, 1994. Details about the Conference will be mailed to former attendees in November, 1993; others may request the mailing by providing their address to Coe. The program and abstracts are provided by Bill Sheridan.
The Steering Committee for the Maize Genetics Conference is:
Kathy Newton, chair
Paul Chomet Tim Helentjaris Pat Schnable
Karen Cone Tom Peterson Sue Wessler
Alfons Gierl Bob Schmidt
