Casting a critical eye on plant stress research

For the benefit of learning

 

"You must learn from the mistakes of others. You can't possibly live long enough to make them all yourself."  Sam Levenson (1911 - 1980)

 

Interpretations

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 and interpretation of transgenic plants for drought resistance – an example

O    Plant sterility under drought stress is caused by antioxidant inefficiency?

O    Drought resistant varieties as an experimental tool to prove a physiological hypothesis – a frequent pitfall

O    Need to understand cause and effect in analyzing drought resistance

O    The greenhouse as a possible source of experimental error

O    Does ABA Sensitivity Enhance Drought Resistance? - The Dilemma

 

Flawed protocols in stress research

O          ... and a letter to Plant Physiology – 2002

O    Improper measurements of plant water status are still being used

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    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

O    Irrelevant drought stress treatments and interpretations in plant physiology experiments – still in view

O    Drought stress in genomics (2013) – Gene expression under drought stress is assessed by pulling seedlings out of nutrient solution and desiccating them in air.

O    A new inventive “drought stress” protocol in a paper published in “Molecular Breeding 2016” journal

O    The disturbing pot size effect in evaluating plant response to drought stress.

O     

Contrarian Data and Views

O    What proportion of declared QTL in plants are false?

O    “Why Genetic Engineering Is Not Solving Agriculture's Drought Problem in a Thirsty World” – a critique

O    “Salt stress or salt shock: which genes are we studying?” – Issues with salinity gene-expression research.

O    Is Arabidopsis thaliana the proper model plant for research?

O    Small heat shock protein (HSP), a consensus factor of stress resistance, found to increase plant sensitivity to heat and salinity stress

O    Overexpression of TaNAC2D Displays Opposite Responses to Abiotic Stresses between Seedling and Mature Stage of Transgenic Arabidopsis

O    ROS are good. A view by Ron Mittler, 2017.

O    Regulating Tradeoffs to Improve Rice ProductionCertain genes may have both positive and negative effects on crop performance
