“…In contrast, the presence of AB at the first node below TFB seemed to suppress elongation of AB at the second node in both types of cultivars. Because emergence of TFB occurred earlier than emergence of AB at the second node [28], the effect of TFB on lateral shoot growth might be stronger than that on AB in both types of cultivars.…”

“…However, in determinatetype cultivars, emergence of TFB did not promote the growth of lateral shoots. The much shorter stem lengths in determinate-type cultivars compared indeterminate-type cultivars [28] suggests that auxin concentrations in the apical organs including TFB might differ much from those of non-flowering terminal buds. Furthermore, auxin concentrations in apical organs including TFB might be related to branching habit in tomato plants.…”

“…Furthermore, there has been little information about the effects of pinching treatments on the harvest term, yield, growth of lateral shoots, flowering, and number of flowers in determinate processing tomatoes, and about the relationship between the growth of lateral shoots and the uptake of mineral nutrients. Therefore, the objective of this study was to clarify and summarize the effects of flower bud or shoot removal on these parameters based on the previous research [28,29].…”

Branch formation might be used as indices for improving productivity in tomatoes. However, there has been little research to elucidate the relationship between the emergence of terminal flower bud (TFB) and the elongation of lateral shoots. Therefore, the effects of flower bud or shoot removal on plant growth, flowering, and yield were investigated. In indeterminate cultivar, the lateral shoot of the second node below TFB was suppressed by flower bud removal but not by shoot removal compared with untreated plants. In determinate cultivar, the opposite results were observed. TFB emergence was affected and not affected during lateral shoot elongation of both type cultivars, respectively. In determinate-type tomato, growth, dry weight, and the distribution of nitrogen and calcium in the lateral shoots in the pinching treatments (shoot removal) were greater than those in the control. The flowering periods and number of flowers per lateral shoot in the pinching treatments were shorter and greater, respectively, than those in the control. Initial weekly yields in the pinching treatments were increased compared with those in the control. From these results, since the branch formation and productivity by flower bud or shoot removal was clarified, it would be useful information for future tomato production.

Studies have shown that reduced nutrient availability enhances microbial diversity around plant roots, positively impacting plant productivity. However, the specific contributions of rhizosphere microbiomes in nutrient-poor environments still need to be better understood. This study investigates the role of Plant Growth-Promoting Rhizobacteria (PGPR) in enhancing the growth ofSolanum lycopersicumunder hydroponic conditions. We hypothesised that nutrient limitation would increase the selection of beneficial bacterial communities, compensating for nutrient deficiencies. Our hydroponic system, with treatments consisting of 50% reduced fertiliser application supplemented with a soil-derived inoculum, exhibited greater bacterial diversity and biomass than controls, suggesting a successful enrichment of PGPR that compensates for nutrient deficiencies. Using 16S rRNA gene sequencing, we found a significant enrichment (p ≤ 0.001) and correlation with beneficial plant traits (p ≤ 0.05) of bacterial genera such asLuteolibacter, Sphingopyxis, andKaistia. Shotgun metagenomics identified the critical role ofMethyloversatilisin nitrogen fixation and other key taxa bacterial proteins in plant-bacteria interactions. Additionally, our findings identify core taxa across different cultivation systems. These results support the potential for microbiome engineering to enhance microbial diversity and plant productivity, offering a path to reduce fertiliser use in agriculture and improve sustainability.
