“Understanding on actinomycetes-mediated stress tolerance in plants is very limited. This study demonstrated for the first time some stress tolerance mechanisms in chickpea via mediation of an actinomycetes strain Streptomyces rochei SM3. Here, we used the strain SM3 for treating chickpea seeds and plants raised from such seeds were challenged with Sclerotinia sclerotiorum and NaCl. Chickpea mortality due to Sc. sclerotiorum infection was suppressed by nearly 48%, and biomass accumulation

was increased by nearly 20% in the salt-stressed condition in SM3-treated plants compared to non-treated plants. Physiological responses in chickpea under the challenging conditions showed that phenylalanine ammonia lyase activities increased in SM3-treated plants. This is followed by accumulation of higher concentrations of phenolics that led to enhanced lignifications in SM3-treated plants compared to non-SM3-treated plants challenged with the same stresses. Antioxidant activities, as assessed through catalase activities and proline accumulation, also increased in SM3-treated plants challenged with both the stresses

compared to non-SM3-treated plants. Investigation at genetic level further showed that the strain Panobinostat SM3 triggered the ethylene (ET) responsive ERF transcription factor (CaTF2) under the challenged conditions. Thus, from this study, we conclude that actinomycetes St. rochei SM3 trigger the ET-mediated defence pathway in chickpea and activates the phenylpropanoid pathway for alleviating the stresses caused by Sc. sclerotiorum and salt in chickpea. “
“The objective of this study was to examine the impact of free

environmental moisture, such as from rainfall, on disease development and mycotoxin production and accumulation in planta. In greenhouse experiments in 2009, two single Fusarium graminearum isolates were used to inoculate spikes of three wheat cultivars: ‘Alsen’, ‘2375’ and ‘Wheaton’ at anthesis. On each wetting event/sampling day (7, 14, 21 or 28 days after inoculation), FHB severity was assessed and five pots of each of the two cultivar/isolate treatments were subjected this website to a wetting event. At the end of the wetting event, the spikes were sampled both from the plants that received the wetting treatment and those that did not and analysed for mycotoxins. Run-off water samples were also taken 3 h after the start of irrigation and immediately after the wetting treatment concluded and analysed for mycotoxins. The results showed despite statistically similar FHB severity, the levels of DON and other mycotoxins detected were significantly lower in the plants receiving a single wetting event compared to the control. The levels of DON in wetted plants were lower up to 36% in ‘Alsen’, 52% in ‘2375’ and 41% in ‘Wheaton’ compared to that of corresponding controls.
