e0“Type 3 was observed in response to all three stresses and led to partial sterility. The microspores completed PGM 1 but a proportion became disoriented from the tapetum and developed no further.”

Other claims from this paper (8)
- Intervention effect Heat stress caused wheat male sterility.
- Intervention effect Water stress caused wheat male sterility.
- Intervention effect Exogenous ABA caused wheat male sterility.
- Observation Heat stress and ABA produced type 1 anther failure through premature tapetal degeneration and locule invasion, causing total sterility.
- Observation Water stress produced type 2 total sterility when microspores lost tapetal contact and the filament degenerated.
- Observation Each stress produced both fully sterile and partly sterile abnormal anther locules.
- Observation Heat and ABA caused similar abnormal development but different proportions of types 1 and 3.
- Observation The findings do not support ABA as the sole primary controller of water stress induced sterility.
