THE FINAL ELBOW. On 25 March, Daniel H. Janzen (PENN) presented
the first in a series of conferences celebrating INBio's 15th
anniversary. Ever on the cutting edge, Dan gave a very stimulating talk about
the seemingly futuristic possibility of a hand-held, satellite-connected DNA
sequencer ("barcoder") for sp. identification. Many of us have been
contemplating the likes of this, as a theoretical possibility, ever since the
advent of DNA sequencing-but never did we imagine it would happen in our
lifetimes! At least for certain organisms (those of special importance to
customs officials and medical doctors), something of the sort is bound to be
in use within a very short time-three years, according to Dan. He has already
tested the gene that seems to work for animals (see, e.g.,
http://www.barcodinglife.com/) by
sending a bunch of butterfly (skipper) pieces, involving cryptic spp., to a
lab and getting back essentially 100% correct IDs (i.e., the material separated
into the same number of spp. that Dan recognizes). The next goal is to
miniaturize and mobilize the technology, and to find a gene that works for
plants. An ancillary goal, of course, is to generate a new round of excitement,
funding and research possibilities in plant taxonomy. Discussions with John
Kress and colleagues at US have led to a promise from them to search for
said gene. Plant taxomomists often react negatively at first but, realizing the
tremendous implications, have begun to think harder and more positively. A
mid-summer meeting in Costa Rica is in the planning stage. A proposed goal of
the early phase of this initiative is to create a DNA barcode library for an
entire national flora (that of Costa Rica), taking into account and exploring
the associated complications, conditionalities, variations, and protocols for
making it functional for sp.-level identifications.
CHICO EL TROTAMUNDO. INB mainstay Francisco Morales attended an
Apocynaceae meeting in Vienna during 31 January-16 February, and visited
herbaria there. Just a month later (17-28 March) he was in Colombia, where he
worked at COL (and various other herbaria in Bogotá) examining material
for families he is preparing for the Manual, especially Apocynaceae, Cunoniaceae,
and Proteaceae.
