Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2028.

Abstract

Bacteria, like other organisms, are infected by viruses, which are called phages. Phage infection can influence the abundance, distribution, genome content, and physiology of their hosts. Thus, understanding phage diversity and ecology is a critical area of study. Photosynthetic cyanobacteria are at the base of the marine food web and are infected by a distinct and poorly described subset of phages that can act as…
