How to extract gene lists following DEG analysis?

Hello,

After gene read counts, I performed DEseq2 using R software. Then, I filtered my DEG file based on pvalue <0.01 & log2FC > |1|.

Then, I conducted functional annotation based on arabidopsis database. The result was as below: enter image description here

Actually, there are almost 30,000 gene annotated. my question is within annotated data, I would like to only extract "photosynthesis-related genes".

How could I achieve this mission?

Thank you.

extract gene lists

You need a definition of photosynthesis-related genes. A brief literature search shows that people have defined such sets in the past. Do you have something specific in mind?
