MaizeGDB project with the mutants of maize (corn)
At FSU in the biology computer lab, the SAS students
produced mutant phenotype images and captions for
a maize genetics database.
http://www.maizegdb.org/
Pictures from the Bass field summer 2004 were selected by the students from a photo
gallery. They made a figure legend and submitted it to Dr. Carolyn Lawrence, curator at
the MaizeGDB, Iowa State University, Ames, IA.
The SAS images that follow will be added to a large online
database that is used by many plant geneticists located
all over the world.

striate leaves1 (sr1) (sr1 P1-ww from stock 101D 12/03). The phenotype caused by the
striate mutation is long white stripes of various sizes, especially common on lower
leaves. (contributed by Z.E., SAS middle school class, Leon Co., Tallahassee, FL.)
striate leaves1
striate leaves1 mutants have
many white stripes on the mature
leaves.

albescent plant1 (al1) - An albino mutant of the corn plant which dies young because it is unable to undergo
photosynthesis. The only way these plants exist is because they feed off the seed endosperm and then some
of the leaves are green, temporarily supporting the growth of large white leaves. The veins are exposed,
making them appear pink. (Submitted by Andrew and Erika, SAS middle school, Leon Co., Tallahassee, FL.)
The lazy plant1 (la1) mutant. Lazy is from a non-lethal mutation that
causes the plant to appear to defy the basic law of gravity. (This
picture was found at cytomaize.org and contributed by Will Taber &
Stephen Hanf, SAS middle school class, Leon Co., Tallahassee, FL)

The P1-wr or Pericarp color1wr (P1-wr) gene, silk color,
from summer 2004. This
allele of the P1 gene makes
the plant’s silks turn a pink
color. This is not a lethal
mutation. This mutation also
causes the cob to turn a
red/pinkish color.

j1 or japonica striping1 mutant
plant. This mutation causes white
stripes on the leaves. It is not
lethal. (Contributed by Sarah H-T.
