Dec 3, 2004 SAS middle school gifted science
class. 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. 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. For
more information, contact Dr. Bass at

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

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.)
6
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

middle school class, Leon Co., Tallahassee, FL)

Rolled leaf1 (Rld1). The mutant phenotype of
three Rld1 plants are shown from the summer 2004
field. (Contributed by Andrew Jernigan and

The P1-wr or Pericarp color1-wr (P1-wr) gene,
silk color, from summer 2004. This allele of the
P1 gene makes the plants silks turn a pink
color. This is not a lethal mutation. This
mutation also causes the cob to turn a
red/pinkish color. (contributed by Cassie and
Krista, SAS middle school class, Leon Co.,
Tallahassee, FL.)

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