November 26: Locus record displays have been greatly improved. Now, nearby loci from high-density maps are included in the record, which allows users to quickly find information on nearby loci from a given locus record. See adh2 for an example of this.

November 21: Try out our new advanced map query!

November 18: Current EST clustering information is now available! Look at ZMtuc02-02-07-11871.1 for an example.

November 14: In response to user feedback, gene records now have significant sequence information directly on the record! Take a look at bz1, for example; note the new "Sequences" section, as well as additional search tools on the right-hand menu.

November 12: All searches now accept * as a wild card in addition to %. Also, the SSR browser has been upgraded significantly due to user feedback; check it out!

November 8: Over the next few days, we're going to be focusing on query optimization, in terms of both finding better matches and getting results faster. If you get some odd results in the next week or so for your searches, let us know.

November 7: There's a new data set to investigate: QTL data. If you have any thoughts/comments for other ways you'd like to access this data, let us know.

November 5: Try out our advanced variation search! The goal was to make filtering through the variation data as easy as possible; let us know if we succeeded, or if there are other features you would like to see.

November 4: A couple of new features today. First is a sequence browser tool, which lets you browse through the sequence data available here and filter it in various fashions. Also new is a gene symbols list, which summarizes the meanings of the gene symbols used on this site.

October 31: Check out our latest nifty tool, the SSR browser! As always, feedback is desired and encouraged!

October 31: Due to some DNS changes, the website will be unavailable for part of Friday morning, November 1. We should be back up by the early afternoon.

October 29: We're looking for ways to further optimize our page layouts. What do you think of this alteration?

October 28: We have a new tool available for examining phenotype data: the phenotype browser. This tool is designed for people who want to just browse through the phenotype data. We provide some filters and are interested in hearing about other filter ideas.

October 23: Take a site tour!

October 18: There's a new data type available: ESTs.

October 16: A new map tool: when you visit a map record (for example, IBM 9, you can now quickly find the other maps from the same experiment at the bottom of the record (in this case, IBM 1-10). In addition, you can also click and find the combined map for all ten chromosomes; for example, here is the complete IBM map.

October 15: A new data type is available for searching and review; take a peek at the phenotype data. We've also added a reference abstract search, so you can search for terms in the reference abstracts we store. You can find this on the reference page.

Ocbober 9: Several new tools today. We now have an image browser, which allows for a visual tour through the variation data; it utilizes our image data and provides an interesting visual way to look at the data. Also, you can now view data by chromosome; this is available both on the menu on the front page (on the left) as well as the data browsing page. This tool summarizes the interesting data for each chromosome in one place.

October 7 Some changes to the website interface were made which only affects Netscape 4 users; they now get a slightly different version of the site with some of the fancier elements taken away, resulting in a display that works much better with Netscape 4. Also, a new data type, gene products, has been added.

October 3: An interesting new tool was added for the study of overgo data; you can find it on the overgo hub page. The tool allows you to do sequence searches on the overgo data, and provides clear and colorful results. Give it a whirl!

October 2: The data types metabolic pathways, stocks, and variations are now available to explore; you can find hub pages for these on the left side of the main page or by clicking on "browse data" on any page on the site.

September 27: Several new features this week. The new datatypes SSR, RFLP, overgo, BAC, and cDNA are available for searches. Also, there are now "hub" pages for each data type; see the left column on the front page. In addition, there's a new section on the menu on the upper right corner of each page entitled "tools," which includes interesting tools of various types; it currently includes three blast variations, GeneSeqer, and a mapped accession number tool. Lots of other little features as you go around, too.

September 20: Protein records are now greatly improved, with related DNA sequences and motifs. See BAA22442 for an example, a fatty acid desaturase.

September 18: A new feature has been added that relates map and sequence data together. When you visit a map (IBM 1, for example), a tool is available on the right hand menu to display the map coordinates with respect to accession numbers (here's that view for IBM 1). Thus, interested parties can dig into sequence data as it relates to the maize maps we have in our database.

September 17: A couple of new features today. First is the beta release of our visual map displayer, which is linked on the right hand side of every map page. Here is a sample visual map display; comments are welcome, as always. The second is the vastly improved sequence records, which include a great deal of additional information about the sequence source and submission details; see AI438620 for an example.

September 12: Linkages between references and loci, references and probes, and references and maps have been established. Now, when you visit a reference record (an example), you'll find links to the materials that that paper describes, as well as links from individual materials back to the reference that describes them.

September 6: Progress is being made in developing "hub" pages for each specific type of data that MGDb can store. Here's such a page for locus data, which also includes a new "advanced search" tool. Comments are welcome.

August 23: You can now search and view map records. Here's a sample map record (UMC 1998 1).

August 22: An interesting new tool connecting locus and sequence data has been added. You can gather all of the ESTs at a particular loci and view them as a group, and then run clustal on this sequence group if you'd like. This tool is available for all loci. You can see what it looks like for sh2. We plan on adding similar tools in the future at the community's request.

August 20: Locus records are now available and are searchable using the form on the upper right of each page. Try a search for shrunken1 if you're interested.

August 5: The various searches have had a 3x increase in speed over the weekend.

August 1: The probe display has been rewritten to correct some of the slowness in linking ZmDB and MaizeDB data. It now loads in roughly 30% of the time compared to earlier. Compare before and after for an example.

July 22: Linkages between ZmDB and MaizeDB data are popping up for the first time on here; also, the full probe record set has been loaded.

July 16: A class browser has just been added. This lets users peruse through the data by data type and provides a more "browsable" method of searching.

July 10: A multitude of small improvements to reference search and display and journal display.

July 9: The reference search has now been optimized; it is roughly 20 times faster than it was previously.

July 8: A reference search is now available! You can use the basic form on each page to access this data set.

July 5: Attempts are being made to make XML displays useful to all, using the probe record as a model. When you visit a probe record, you can see both a stylized and a plain XML display. Let us know if you have any comments.

July 1: Record displays now have a "printer-friendly" option that eliminates some portions of the interface for better & smoother printing.

June 28: The "Anything" search has been rewritten; now, when there is only one match in the entire site, you are redirected there automatically.

June 27: Large number of changes today. These are summarized in this changelog.

June 26: Cleaned up some display issues for some older browsers, specifically Netscape 4. Let us know if you observe anything unusual in terms of page layout.

June 24: Consideration is being made of adding a section of interesting reports, which are one page summaries of information sets that might be of interest or use to the maize community. Got suggestions for report ideas? Let us know.

June 24: Added a person/organization browser. We are looking for suggestions for more filters for it.

June 21: In attempting to make our data widely available and in many forms to address the needs of the maize community, development of a set of XML standards which will be used to provide data from us and that (hopefully) other databases will adopt. Take a look at our first attempted standard, a DTD for probe data.

June 21: Added two new filters to the probe browser: the ability to eliminate probes without a designated preparer and the ability to eliminate probes that are currently unavailable. We're looking for suggestions for more filters.
