Title

Salicylic acid reverses pollen abortion of rice caused by heat stress

Baohua Feng; Caixia Zhang; Tingting Chen; et al. BMC Plant Biology 2018. doi:10.1186/s12870-018-1472-5

Other claims from this paper (6)

Intervention effect Under heat stress, salicylic acid decreased reactive oxygen species accumulation in anthers.
Intervention effect Salicylic acid prevented tapetum programmed cell death and degradation.
Mechanism The genes EAT1, MIL2 and DTM1 are involved in tapetum development in this process.
Intervention effect Exogenous salicylic acid spray gave significantly higher pollen viability under heat stress than control sprays.
Intervention effect Salicylic acid or PAC plus H2O2 treatment sharply increased H2O2 relative to other treatments.
Intervention effect Under control conditions, salicylic acid treatments showed no significant difference in pollen viability or seed-setting rate.

Title

Integrative Transcriptomic and Biochemical Profiling Reveals Bacillus amyloliquefaciens JL54 Primes Larix olgensis Defenses Against Neofusicoccum laricinum Attack

Xiangyu Zhao; Fengze Yang; Lingyu Kong; et al. Plants 2026. doi:10.3390/plants15081181

Other claims from this paper (8)

Intervention effect JL54 pretreatment reduced shoot blight disease incidence in Larix by 12.5%.
Intervention effect JL54 pretreatment achieved 43.75% shoot blight control efficacy in Larix.
Intervention effect JL54 pretreatment maintained Larix host vigor.
Observation At 0 h post-inoculation, Larix defense showed upregulation of cutin, suberin and wax biosynthesis pathways.
Observation At 12 h post-inoculation, Larix responses were dominated by ribosome and proteostasis related pathways.
Intervention effect JL54 colonization reduced Larix malondialdehyde content by 27.2%.
Intervention effect JL54 colonization significantly increased POD, PAL and GST defense enzyme activities in Larix.
Mechanism Phytohormone profiling implicated JA signaling as central to JL54-induced systemic resistance and preceding pathogen containment.
