Our friend Christopher, K6FIB, @drmna_info on Twitter, lives in
Salem, Oregon, so he experienced the extreme heat that affected
the northwest USA and western Canada during the past week. I
asked Christopher to let us know how his family coped ...

It was REALLY HOT here in Salem, but we had time to prepare. We
bought ice, bottles of mineral water and bottles of fruit
juice. My thought was water with minerals and vitamins should
help keep dehydration away. Keeping hydrating drinks flowing
all day, we stuck with meals that required little to no
preparation - leaning heavily on salads, vegetables and fruit
with added canned chicken, salmon or tuna for meats.

Closing and covering all the windows, we went into the basement
during the day. Early in the morning and after sunset, I
watered the garden for longer than normal. People in the
Pacific Northwest generally are prepared for some 90 degree
(32C) weather, but much later than June. I'd expect us normally
to be closer to 75 degrees (24C) at this time of year. This
evening [June 28], marine air has come up into the Willamette
valley and significantly dropped the temperatures. From our
ridiculous high today, we are hovering around 92 degrees (33C)
at almost 7PM.

Add 117 degrees (47C) in June to the other ways Salem made
national and international news in the last 12 months! You
might remember the days of wildfires, sky darkening smoke and
unbreathable air, and an ice storm that pushed over huge old
trees and knocked out power to some for over a week.
Regardless, we are still here and proud Oregonians.

From North Carolina State University:

Hot Nights Confuse Circadian Clocks in Rice, Hurting Crop Yields

Matt Shipman
June 29, 2021

Rising nighttime temperatures are curbing crop yields for rice,
and new research moves us closer to understanding why. The study
found that warmer nights alter the rice plant's biological
schedule, with hundreds of genes being expressed earlier than
usual, while hundreds of other genes are being expressed later
than usual.

"Essentially, we found that warmer nights throw the rice plant's
internal clock out of whack," says Colleen Doherty, an associate
professor of biochemistry at North Carolina State University and
corresponding author of a paper on the work.

"Most people think plants aren't dynamic, but they are. Plants
are constantly regulating their biological processes – gearing up
for photosynthesis just before dawn, winding that down in the
late afternoon, determining precisely how and where to burn their
energy resources. Plants are busy, it's just difficult to observe
all that activity from the outside."

And what researchers have learned is that the clock responsible
for regulating all of that activity gets messed up when the
nights get hotter relative to the days.

"We already knew that climate change is leading to increased
temperatures globally, and that nighttime temperatures are rising
faster than daytime temperatures," Doherty says. "We also knew
that warmer nights hurt rice production. But until now, we had
very little insight into why warmer nights are bad for rice.

"We still don't know all the details, but we're narrowing down
where to look."

Research that addresses rice yield losses is important because
rice is an essential crop for feeding hundreds of millions of
people each year – and because a changing climate poses
challenges for global food security.

To better understand how warm nights affects rice, Doherty worked
with an international team of researchers – including Krishna
Jagadish of Kansas State University and Lovely Lawas of the
International Rice Research Institute – to study the problem in
the field. The researchers established two study sites in the
Philippines. Temperatures were manipulated in different areas of
each study site using either ceramic heaters or heat tents.

A research team led by Jagadish used the ceramic heaters to
maintain experimental plots at 2 degrees Celsius above the
ambient temperature, and took samples from the rice plants every
three hours for 24 hours. Control plots were not heated, but were
also sampled every three hours during the same 24-hour period.
These tests were repeated four times. The heat tents were later
used to validate the results from the ceramic heater tests.

Meanwhile, a team led by Doherty found that more than a thousand
genes were being expressed at the "wrong" time when nighttime
temperatures were higher. Specifically, hotter nights resulted in
hundreds of genes – including many associated with photosynthesis
– becoming active later in the day. Meanwhile, hundreds of other
genes were becoming active much earlier in the evening than
normal, disrupting the finely tuned timing necessary for optimal
yield.

"It's not clear what all of these genes do, but it is clear that
these conflicting schedule shifts are not good for the plant,"
Doherty says.

The researchers found that many of the affected genes are
regulated by 24 other genes, called transcription factors. Of
those 24, four of the transcription factors were deemed most
promising for future study.

"We need to do additional work to figure out exactly what's
happening here, so that we can begin breeding rice that's
resilient against warmer nights," Doherty says. "Rice is an
important food crop. And other staple crops are also affected by
hotter nights – including wheat. This isn't just an interesting
scientific question, it's a global food security issue."

The paper, "Warm Nights Disrupt Global Transcriptional Rhythms in
Field-Grown Rice Panicles," is published in the journal
Proceedings of the National Academy of Sciences of the United
States of America. First author of the paper is Jigar Desai, a
former Ph.D. student at NC State. The paper was co-authored by
Lawas; Jagadish; Ashlee Valente and Adam Leman of Mimetics LLC;
and Dmitry Grinevich, another former Ph.D. student at NC State.

The work was done with support from the U.S. Department of
Agriculture under a grant from the National Institute of Food and
Agriculture (NIFA).
