“…Conversely, it has also been shown that many fungal pathogens are equipped with effectors to suppress chitin-triggered immunity or escape from the detection of fungal chitin by host receptors [6]. Recent findings also indicate that chitin-related molecules serve as a symbiotic signal in the interaction between arbuscular mycorrhizal fungi and host plants [7]. In this review, we focus on the plant-fungal interactions mediated by chitin and related molecules, which govern 'friend and foe' relationships between these organisms, and also the arms race for chitin-triggered immunity.…”

“…The interaction between host plant and AMF begins with an exchange of signals well before physical contact occurs. Plant‐derived strigolactones (Nadal & Paszkowski ; Schmitz & Harrison ) as well as flavonoids (Scervino et al . , ; Steinkellner et al .…”

While the biochemical function of calcium and calmodulin-dependent protein kinase (CCaMK) is well studied, and plants impaired in the expression of CCaMK are known not to be infected by arbuscular mycorrhizal fungi (AMF) in glasshouse studies, the whole-plant and ecological consequences of CCaMK silencing are not well understood. Here we show that three independently transformed lines of Nicotiana attenuata plants silenced in CCaMK (irCCaMK) are neither infected by Rhizophagus irregularis in the glasshouse nor by native fungal inoculum in the field. The overall fungal community of field-grown roots did not differ significantly among empty vector (EV) and the transgenic lines, and the bacterial communities only showed minor differences, as revealed by the alpha-diversity parameters of bacterial OTUs, which were higher in EV plants compared with two of the three transformed lines, while beta-diversity parameters did not differ. Furthermore, growth and fitness parameters were similar in the glasshouse and field. Herbivory-inducible and basal levels of salicylic acid, jasmonic acid and abscisic acid did not differ among the genotypes, suggesting that activation of the classical defence pathways are not affected by CCaMK silencing. Based on these results, we conclude that silencing of CCaMK has few, if any, non-target effects.

The Indonesian sugarcane production in the dryland was not optimal due to physiological stress. The research to improve their physiological characteristics by arbuscular mycorrhizal application was conducted at inceptisol soil from April 2014 to February 2015, using factorial completely randomized design. The first factor was clones PS864, Kidangkencana, PS881, Bululawang, and VMC, whereas the second factor was timing of arbuscular mycorrhizal inoculum applications i.e.: in the field, nursery, and control. The results show that the mycorrhizal application in the nursery significantly increased the infection percentage (41.3%) at the age of 1 week after transplanting to the field. There are differences in physiological and growth performance of clones by the effect of timing of mycorrhizal application. Bululawang with mycorrhizal application in the nursery stage tended to have better physiological performance such as chlorophylls a, b, and total chlorophyll, photosynthesis rate, intercellular CO 2 concentration, leaf area, as well as the weight of stem biomass. Mycorrhizal application in the nursery stage showed the highest increase of net assimilation rate on the PS864 and, BL clones, and the highest crop growth rate on the PS864, KK and BL clones. The mycorrizal inoculum application in the nursery increased the biomass weight of stem (11-61.1%). Infection percentage of mycorrhiza was positively correlated with the biomass weight with r 2 values of 0.54.
