Deficiency of SMO2 resulted in disorganization of the stem cell niche (SCN) and the presence of dead cells in RAM, independent of DNA damage. Moreover, following chemically induced wounding, excision of root tips, or removal of whole roots, the regeneration capacity of <em>smo2</em> mutants was dramatically lower than that of wild-type plants. Mechanistically, SMO2 is necessary for 18S rRNA methylation at position G1581, which may be associated with abnormal ribosome profiles in <em>smo2</em> mutants. Further analysis showed that deficiency of SMO2 markedly reduced the translation efficiency of genes involved in polar auxin transport, thereby reducing auxin accumulation in the RAM. Surprisingly, an additional deletion of ANAC082, which encodes a known transcriptional mediator of ribosomal stress-induced developmental adaptations, effectively restored the disordered SCN and cell death phenotypes in <em>smo2</em> mutants. Collectively, our findings demonstrate that SMO2-mediated translational regulation plays an important role in auxin accumulation in root tips.

The TAGFA 16:1ω5 was used as a marker of AM fungal storage structures, whereas TAGFA 18:2ω6 was used as a marker of saprotrophic fungal storage structures. Our results showed that the rhizospheres of AM and non-mycorrhizal (NM) plants differed significantly in their TAGFA composition, a finding reported here for the first time. In particular, root colonization by <em>R. irregularis</em> increased TAGFA 16:1ω5 by 76 % and decreased TAGFA 18:2ω6 by 45 %, suggesting that less carbon was allocated to saprotrophic fungal storage structures. This redistribution of carbon in AM plant rhizospheres strongly influenced the content of cyclopropyl fatty acids in microbial cytomembranes, which are widely used as classical indicators of nutritional stress in soil microorganisms. The cyclopropyl-to-precursor ratio decreased significantly in AM rhizospheres, indicating that AM symbiosis effectively alleviates microbial stress in olive rhizospheres. These marked changes in the AM rhizosphere were associated with metabolic rearrangements in olive leaves. AM symbiosis generally had a positive impact on amino acid levels, particularly those of the glutamate family (glutamic acid, arginine, ornithine, and glutamine). Metabolic reprogramming also enhanced other pathways of secondary metabolism, notably flavonoids (luteolin <em>7-O-</em>glucoside and luteolin 7-O-rutinoside) and the secoiridoid oleuropein. Taken together, our results highlight the pivotal role of AM fungi in regulating the allocation of photosynthates from aboveground tissues to belowground structures, including roots and their associated mycorrhizal partners, thereby driving rhizospheric changes and priming the accumulation of defensive compounds in olive leaves.

This ON-OFF bearing cycle significantly diminishes the profitability of apple orchards. This phenomenon generally occurs in all apple varieties, but is much more pronounced in some genotypes (biennial-bearing) than in others (regular-bearing). Although apple fruits of the current season and flower buds for the next season develop simultaneously, it remains unclear whether biennial bearing is triggered by signaling compounds from the fruits or results from carbohydrate competition between growing fruits and buds. To test the carbohydrate competition hypothesis, we analyzed nine carbohydrates in bourse buds of the biennial-bearing cultivar ‘Fuji’ and the regular-bearing cultivar ‘Gala’. Bud samples were collected from high-cropping (ON) and non-cropping (OFF) trees during the period of flower bud formation. Our results showed no evidence of carbohydrate deficiency in buds from ON-trees compared to those from OFF-trees. Contrary to the hypothesis, the concentrations of glucose and fructose in ‘Gala’ were higher in buds from ON-trees. Furthermore, we analyzed 15 carbohydrates in the leaves of nine regular-bearing and eight strongly biennial-bearing apple cultivars and found no clear connections between carbohydrates in leaves and bearing behavior of these cultivars.

Functional studies in mosses, and angiosperms reveal conserved roles of Tre6P in vegetative growth, and the initiation of sexual reproduction, underscoring its potential as a conserved signalling metabolite.
