Observation A 50% grain yield decrease occurred at about 31 mM NaCl with 0.04 x HS.
Observation Salt tolerance was higher at full macronutrient concentration.
Association Grain yield declines were closely related to declining leaf number.
Association Grain yield declines were closely related to declining tiller number.
Mechanism The authors infer salinity mainly affects early growth stages.
Recommendation The authors recommend increasing nutrient supply in nutrient-poor saline soils.
Recommendation The authors recommend salt elimination around roots during early wheat development.
Recommendation The authors recommend increasing main stem density by seeding more densely.
Recommendation Early salt elimination and increased seeding density were expected to raise yield more than added nutrients at moderate and sufficient nutrient levels.

Observation Three selected inbreds had above-average yield and small ASI across environments.
Association ASI and grain yield were significantly correlated with three microsatellites.
Association The selected alleles also favored ASI decrease.
Association Markers explained 5.7% to 22.4% of ASI variation across environments.
Association Markers explained 4.6% to 8.1% of yield variation across environments.
Method / resource Partial least squares interactions analysis identified alleles with strong genotype-specific effects and interactions.

Reduction of MDHAR activity in cherry tomato suppresses growth and yield and MDHAR activity is correlated with sugar levels under high light

Vincent Truffault; Noé Gest; Cécile Garchery; et al. Plant Cell & Environment 2015. doi:10.1111/pce.12663

Other claims from this paper (9)

Intervention effect Independently of the light regime, early growth of all organs was slower in MDHAR-silenced cherry tomato lines.
Intervention effect MDHAR silencing decreased final fruit yield.
Intervention effect Photosynthesis was altered in MDHAR-modified lines.
Intervention effect Accumulation of hexoses and sucrose was altered in a light-dependent manner in plantlets.
Intervention effect Sucrose accumulation was repressed in young fruits of MDHAR-silenced lines.
Intervention effect The phenotype of MDHAR-silenced lines was partially restored by reducing fruit load.
Association MDHAR activity is correlated with sugar levels under high light in cherry tomato.
Mechanism Ascorbate and MDHA appear to be involved in control of growth and sugar metabolism in cherry tomato.
Recommendation The associated enzymes could be potential targets for yield improvement.
