Time-lapse photography shows the effect of a gene
that enables rice to withstand long-term flooding
The SUB1 gene--identified by IRRI and University of California (UC) researchers--allows rice to survive complete submergence for up to 17 days as illustrated
by the rice still standing to the left and right of the scientist in the photo at left. Seeing is believing!
Even better than a static photo to show the effect of
SUB1 is a time-lapse video, spanning 127 days from 14 June to 16 October 2007 in an IRRI research plot. Prepared by IRRI’s
photography and video section, see this 40-second clip on YouTube further
below.
The photo at right shows the end-result harvest of the plot on
16 October 2007 (click to enlarge), which yielded the equivalent of 3.8
tons/hectare for IR64+SUB1 and 1.4 tons/hectare for IR64.
Prepared by IRRI’s photography and video section, the
first video shows the effect of the
SUB1 gene in a 40-second time-lapse video, spanning 127 days from 14
June to 16 October 2007 in an IRRI research plot.
The second video shows
IRRI's work on both drought and flood tolerance in rice. Sometimes there is
not enough water in rice fields and sometimes there is too much.
In November 2008, IRRI and UC scientists ceremoniously harvest a rice
variety with the flood-tolerant gene on the research station of the Bangladesh Rice Research Institute
near Rangpur. See third video below.
The fourth video below shows a 9:55 overview of visits to research stations and
farmers' fields in Bangladesh and India, 1-8 November 2008.
In the fifth video, IRRI's Sub1 work is featured on
CNN's Spirit of Survival.
