B-48 3 claims

Interactor role: other, pathogen

Literal values, not normalised. 183,098 distinct spellings cover 1,706,259 claims; only letter case and spacing are merged, so “maize”, “corn” and “Zea mays L.” are three separate entries here. The By interacting organism view merges spellings of one organism through NCBI Taxonomy.

Colletotrichum echinochloae: A Potential Bioherbicide Agent for Control of Barnyardgrass (Echinochloa crus-galli (L.) Beauv.)

Qiongnan Gu; Shihai Chu; Qichao Huang; et al. Plants 2023. doi:10.3390/plants12030421

Other claims from this paper (7)

Observation The barnyardgrass-pathogenic isolate was identified as Colletotrichum echinochloae.
Intervention effect Inoculation with C. echinochloae significantly reduced barnyardgrass fresh weight.
Observation Isolate B-48 was highly pathogenic to barnyardgrass at the three- to four-leaf stages.
Intervention effect At 1 × 107 spores/mL, inoculated barnyardgrass fresh weight fell by more than 50%.
Observation The fungal strain was safe for rice.
Observation The fungal strain was safe for most plant species.
Recommendation The authors proposed the strain as a future barnyardgrass mycoherbicide in paddy fields.

“The infectivity of Agrobacterium tumefaciens strain B6 was inhibited about 50% when these bacteria were inoculated on potato discs with equal viable cell counts of a weakly virulent strain of A. tumefaciens (B-48) or autoclaved strains of B6 or B-48”

Title

Agrobacterium tumefaciens Site Attachment as a Necessary Prerequisite for Crown Gall Tumor Formation on Potato Discs

Walter Glogowski; Alan G. Galsky PLANT PHYSIOLOGY 1978. doi:10.1104/pp.61.6.1031

Other claims from this paper (6)

Intervention effect Autoclaved strains of B6 or B-48 also inhibited infectivity of B6 on potato discs.
Intervention effect Inhibition by B-48 or autoclaved B6 was still obtained when added up to 10 minutes after viable B6.
Intervention effect Maximum inhibition occurred when cells were added 10 minutes before B6.
Intervention effect No inhibition occurred when B6 was added with a Gram-positive bacterium or yeast cell.
Intervention effect Inhibition occurred when B6 was added simultaneously with other Gram-negative cells.
Mechanism Specific bacterial attachment within 10 minutes is suggested to be necessary for tumor formation on potato discs.
