Title

Increased Viral Yield and Symptom Severity Result from a Single Amino Acid Substitution in the Turnip Yellow Mosaic Virus Movement Protein

Ching-Hsiu Tsai Molecular Plant-Microbe Interactions 1993. doi:10.1094/mpmi-6-268

Other claims from this paper (7)

Mechanism U1888-->C caused increased symptom severity through a tyrosine-to-histidine substitution in movement protein.
Observation The substitution did not affect coding by ORF-206.
Intervention effect The mutation produced fourfold higher viral product accumulation in infected Chinese cabbage leaves.
Intervention effect The mutation did not affect viral replication in isolated protoplasts.
Mechanism The authors suggest that improved viral spread explains increased viral yield and symptoms.
Intervention effect U1888-->C did not affect viral yield in turnips.
Intervention effect U1888-->C did not affect symptoms in turnips.

Title

Estimates of genetic parameters of quantitative resistance to bacterial leaf blight of rice variety IR26 and their implications in selection.

Toshiaki YAMADA Ikushugaku zasshi 1986. doi:10.1270/jsbbs1951.36.112

Other claims from this paper (10)

Observation IR26 resisted all five bacterial groups in Japan.
Observation F3 lines differed in nonspecific resistance.
Observation Bacterial groups differed in aggressiveness.
Observation Bacterial groups did not differ in virulence.
Method / resource Individual F2 selection was effective for resistance.
Intervention effect Selection using one bacterial group improved resistance to it and the others.
Method / resource Selection for broad resistance could be achieved without inoculating all bacterial groups.
Observation IR26-derived quantitative resistances had high heritability.
Association Resistances were highly correlated genotypically and phenotypically.
Method / resource Aggressiveness on the resistant parent estimated aggressiveness on a hybrid population.

Title

[Competing ability of Rhizobium trifolii strains and efficiency of clover nitraginization on spent peat mosses].

L N Krylova; A T Novikova PubMed 1977

Other claims from this paper (4)

Observation Industrial strains 311a and 347a had sufficiently high competing ability.
Intervention effect Strains 311a and 347a increased clover yield on exhausted turf peats of the Kirovsk Region by 26--29%.
Intervention effect New strains 313b and 329b also stimulated clover.
Recommendation The recommended clover seed inoculation dose is 50,000 nodule bacteria per seed.
