e1“Two Neofusicoccumparvum isolates and a UV mutant were characterized for their phytotoxin production in vitro, their pathogenicity on grapevine, and their genome sequenced”
e4“The isolate Bourgogne S-116 (Np-B) produced 3-fold less (-)-terremutin and high amounts of (R)-mellein, but it was less aggressive on grapevine than Np-Bt67”
e0“since isolate/mutant non-producing these toxins in vitro is pathogenic”

Other claims from this paper (12)
- Association Isolate Np-Bt67 produced a high level of (-)-terremutin and almost no (R)-mellein.
- Association Isolate Np-Bt67 was the most aggressive on grapevine, triggering apoplexy.
- Intervention effect Purified (-)-terremutin did not induce similar symptoms on grapevine.
- Association Isolate Bourgogne S-116 (Np-B) produced 3-fold less (-)-terremutin than Np-Bt67.
- Association Isolate Bourgogne S-116 (Np-B) produced high amounts of (R)-mellein.
- Association Isolate Bourgogne S-116 (Np-B) was less aggressive on grapevine than Np-Bt67.
- Association UV9 mutant no longer produced (-)-terremutin.
- Association UV9 mutant overproduced (R)-mellein by 2.5-fold.
- Association UV9 mutant was as pathogenic on grapevine as its parent.
- Observation NpB-UV9 differed from its parent by simple mutations in two genes, one of them the transcription factor UCR-NP2_6692.
- Association Challenge with N. parvum or purified phytotoxins upregulated SA-dependent defenses in grapevine.
- Association (-)-terremutin interfered with JA/ET-dependent defenses of grapevine.
