Title

Rapid Equilibration of Leaf and Stem Water Potential under Field Conditions in Almonds, Walnuts, and Prunes

Allan Fulton; Richard Buchner; Cyndi Gilles; et al. HortTechnology 2001. doi:10.21273/horttech.11.4.609

Other claims from this paper (7)

Method / resource A 10-min or longer equilibration period was suitable for accurate stem water potential measurements.
Method / resource About 10 leaves with 10-min equilibration reduced time-related SWP measurement error to 0.05 MPa.
Recommendation One leaf per tree from 10 trees should provide an accurate orchard water status mean where tree growth and health are uniform.
Recommendation More variable orchards may need a larger sample.
Observation Midmorning and midday SWP showed similar seasonal patterns and irrigation responses.
Method / resource Prediction errors up to 0.3 MPa occurred with unusual VPD changes.
Recommendation Direct midday SWP measurement remains recommended.

Precipitation, Temperature and Tillage Effects upon Productivity of a Winter Wheat–Dry Pea Rotation

William A. Payne; Paul E. Rasmussen; C. Chen; et al. Agronomy Journal 2000. doi:10.2134/agronj2000.925933x

Other claims from this paper (8)

Association Spring precipitation strongly influenced dry pea yield.
Intervention effect Tillage had little to no effect on dry pea yield.
Method / resource A precipitation distribution and heat stress model predicted pea yield well.
Association Winter precipitation influenced wheat yield more than spring precipitation.
Intervention effect Fall SWP-SKW reduced wheat yield by about 400 kg ha −1.
Mechanism Poor weed control probably explains lower wheat yield.
Recommendation Dry pea is considered an agronomically viable rotation substitute for summer fallow or fresh pea.
Recommendation The authors recommend evaluating minimum-tillage wheat yield decline against costs and improved management.

The Recessive Epigenetic swellmap Mutation Affects the Expression of Two Step II Splicing Factors Required for the Transcription of the Cell Proliferation Gene STRUWWELPETER and for the Timing of Cell Cycle Arrest in the Arabidopsis Leaf

Nicole K. Clay; Timothy Nelson The Plant Cell 2005. doi:10.1105/tpc.105.032771

Other claims from this paper (15)

Observation The swellmap mutant had fewer, smaller organs and cells.
Observation Final cell size increased and partially compensated for reduced cell number.
Mechanism The mutation caused early arrest of organ primordium proliferation.
Observation The mutation possibly slowed cell division.
Observation The epigenetic smp mutation defined SMP1 and affected SMP1 and SMP2 expression.
Observation SMP1 and SMP2 encode similar CCHC zinc finger proteins.
Intervention effect Genetic knockouts showed the genes are redundant and essential.
Association SMP1 expression coincided with cell proliferation regions.
Intervention effect SMP1 overexpression increased organ cell number.
Intervention effect SMP1 overexpression partly decreased cell expansion.
Observation The smp mutation did not affect CYCD3;1 or CDC2A expression.
Observation SWP protein resembled Mediator complex subunits.
Intervention effect Introducing SWP cDNA restored mutant plants to wild type.
Observation SMP1 and SMP2 expression was restored in SWP cDNA lines.
Mechanism Authors propose splicing factors and a Mediator-like complex time leaf cell cycle arrest.
