Given the importance of xylan in plant cell wall structure and in the development of plant disease resistance, defining the function of xylan-modulating enzymes will contribute significantly to our understanding of plant biology and enhance the ability to engineer plant disease resistance. In order to further understand the potential role of xylan-modulating enzymes in plant disease resistance, the aims of this project are to: 1) identify and characterise Arabidopsis plants with altered xylan structure and properties; 2) determine the role of xylan-modulating enzymes in the cell wall during plant infection; and 3) develop an Arabidopsis transgenic line expressing the xylan-modulating enzyme Cor413c. A combination of targeted mutagenesis, phenotyping and transgenic expression studies will be used to characterise the impact of altered xylan structure and properties on plant disease resistance. Furthermore, as each of the enzymes identified to date is associated with the cell wall, the biochemical and biophysical properties of the xylan will be examined to gain insight into how the plant cell walls are remodelled during infection. Finally, the xylan-modulating enzymes identified in Arabidopsis thaliana will be expressed in an Agrobacterium-mediated transient expression system and the transgenic lines will be used to screen for a mutant line with altered xylan structure. This will provide a high-throughput system for identifying xylan-modulating enzymes and should also facilitate the isolation of these enzymes in bacterial hosts."Q:
Iterating through the numbers?
I am doing a maths problem from the book "Practical Programming for the Unix Environment" and I'm currently stuck on the following exercise:
"If the first four prime numbers are added to form a sequence whose length is
greater than or equal to 6, find the first odd number in that sequence.
Hint: Do not add each of the first four prime numbers to itself. "
I have tried to use basic loops, but I keep running into problems that I am not able to handle.
The hints I have received have been that there are some rules I have to apply and that there should be some sort of pattern.
My solution so
