Casting a critical
eye on plant stress research For the benefit of
learning |
O Basic problem in the interpretation of plant water status in plants
under stress – an example
O ...
and a letter to Plant Physiology –1996
O Flawed evaluation of
transgenic plants for drought resistance – an example
O ... and a letter to Plant
Physiology - 2002
O Plant sterility under drought
stress is caused by antioxidant inefficiency?
O What proportion of declared QTL in plants are
false?
O Improper measurements of plant water
status are still being used
O A response to stress does not
necessarily constitute adaptation to stress
O Improper measurements of plant water
status are still being used (#2 )
O Irrelevant stress protocols used and
reported in genomic research
O Irrelevant stress protocols used and
reported in genomic research-II
O Need to understand cause and effect
in analyzing drought resistance
O Field plot size and drought stress
phenotyping
O Expression of stress resistance genes in the lab and the field
– not necessarily the same
O The greenhouse as a possible source
of experimental error
O Physiological
and developmental problems encountered by in vitro cultured plants
O In a genomics study drought stress
was applied to leaf discs dried in air for 2 hours
O … And still unrealistic drought stress treatment in a genomics
study – seedlings dried for 0.5 to 2h
