leaf-or-stem spot lesion environment

habitatmech:BACDIVE.31392c69b9 ·OTHER ·UNGROUNDED REVIEWED

An environment associated with a plant part or small plant which is determined by a discrete necrotic or chlorotic spot lesion on a leaf or stem of a living plant, and which is formed by a localized infection that does not spread systemically through the host. — HabitatMech

Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

CONFIRM_UNGROUNDED 2026-08-14 · claude-opus-5
Confirmed UNGROUNDED: no ontology term fits this concept. Cohort review: a leaf-or-stem lesion. PO:0009047 'stem' drops the leaf and is also the target of 'Rot-Root,Stem', so adopting it would merge two different plant diseases onto one record. (source concept habitatmech:BACDIVE.31392c69b9)
DEFINED 2026-09-06 · codex-gpt-5
Defined as 'leaf-or-stem spot lesion environment' under ENVO:01001057 'environment associated with a plant part or small plant'. Definition authored from the record's committed deep-research report under research/habitats/, read in full; no new paid research was commissioned. The report confirms BacDive's Infection > Plant infections > Spot (Leaf,Stem) source denotes a localized plant spot lesion rather than the healthy leaf or stem organ. ENVO:01001057 'environment associated with a plant part or small plant' is the tightest vendored genus while ENVO lacks a shared plant-infection-site environment parent. PO:0009047 'stem' drops the leaf disjunct and would collide with both Rot-Root,Stem and Stem-Branch; PO:0025034 'leaf' drops the stem disjunct; ENVO:01000170 'indeterminate root nodule infection zone' is a symbiotic, root-specific near miss; disease, trait, and clinical necrotic-lesion terms are the wrong entity type.
