If corn plants are grown at a high density, they will be taller. What is one reason for this?
The Ti plasmid needed to be altered by plant scientists before it could be used to make transgenic plants. Why was this?
Suppose that you were trying to develop a new crop by domesticating a grass species (species Z) that had not been used in agriculture. One of the problems that you encountered is the seed pods shatter asynchronously leading to a big loss of seed. What approach would you take to solve this problem?
Root gravitropism is primarily the result of:
The SHP and IND genes are both required for valve margin identity. When you examine fruit from the shp mutant (lacks the SHP transciption factor), you find that the IND gene is no longer expressed in the fruit. What is your interpretation of this result?
Which of the following does not occur in the pye mutant:
Expression of the FUL gene throughout the fruit results in:
