Summary: Fruit consumption is essential for a balanced diet, but the challenge of meeting the increasing demands of a growing population is driving strategies to improve fruit production and nutritional quality. Targeted modifications to plasmodesmata have the potential to enhance fruit development, but understanding of the regulation mechanisms in this context remains limited.

Summary: During long distance transport in higher plants, solutes are continuously released and retrieved, with sugars and amino acids in the stem being used for storage or nourishment of parenchymatic tissues. Modifying export/import capacities along the transport phloem could be a powerful tool for increasing crop plant productivity.

Summary: This study found that the expression pattern of PpSOT3 differs in watercore-susceptible and watercore-resistant pear cultivars. The accumulation of intercellular sorbitol was higher in watercore fruit and the expression of PpSOT3 was significantly inhibited. Further experiments showed that PpSOT3 is a PCMBS-sensitive sorbitol transporter and plays an important role in the occurrence of watercore by modulating the level of intercellular sorbitol content.

Summary: Sweet sorghum is a promising bioenergy source due to its high biomass and soluble sugar yield. This study reveals that loss-of-function alleles at the Dry locus have been selected during sweet sorghum domestication, and decapitation can further increase sugar accumulation. A better understanding of the mechanisms underlying soluble sugar accumulation in sweet sorghum stems, as well as the Dry locus, is essential for maximizing sugar yields.

Summary: The tobacco BY-2 cell line is widely used in plant cell biology research. A microfluidic device was developed to trap and monitor the physiological activity of BY-2 cells. The device successfully trapped cell filaments at specific locations, allowing real-time observation of cell activity. The experiments also confirmed cell survival and permeability using fluorescent proteins.

Summary: Differences in host gene expression may result in different symptoms of phytoplasma diseases in genotypes of the same plant species. Leaf reddening in pear trees may be related to increased sugar levels and enhanced immune responses in multiple tissues, while leaf curling may be due to water stress caused by dysfunctional roots.

Summary: This study identified 56 SNPs associated with fruit traits through genome-wide association studies. New loci related to individual sugar accumulation were discovered, and candidate genes for the underlying QTLs were inferred using apple genome information. Genomic selection accuracy for sucrose, fructose, and glucose was relatively high, indicating the potential to select individuals with desired sugar contents.

Summary: Plants lack structures resembling animal synapses, despite having complex cell contacts and signaling mechanisms that do not support synaptic transmission. While the phloem serves as a conduit for electrical signaling, the characteristics of this process are not comparable to neuronal network information processing.

Summary: This review provides an update on recent advances in grafting and discusses potential new applications in agriculture. Grafting is a traditional horticultural technique that utilizes plant wound healing mechanisms to join two different genotypes into one plant. Recent studies have challenged previous beliefs about grafting monocotyledonous plants and the compatibility between different scion/rootstock combinations, opening up new possibilities for research and applications in agriculture. The review focuses on describing and evaluating these recent advances, particularly the molecular mechanisms behind graft union formation and genotypic compatibility.

Summary: This study reveals that heat stress induces callose accumulation at the plasmodesmata connecting sieve element and phloem pole pericycle, resulting in decreased root meristem size and inhibition of phloem unloading. It further identifies CALLOSE SYNTHASE 8 (CalS8) as a negative regulator of thermotolerance in Arabidopsis roots by decreasing plasmodesmal callose deposition.

Summary: This study identified key sorbitol metabolism-related genes in Rosaceae species and found that the sorbitol pathway genes were expanded through dispersed and tandem gene duplications in the sorbitol present group (SPG). The sorbitol dehydrogenase (SDH) and sorbitol-6-phosphate dehydrogenase (S6PDH) clade A were under stronger purifying selection in SPG, while the sorbitol transporter (SOT) genes were under positive selection in SPG.

Summary: The study identified the CSE gene family from Pyrus bretschneideri, showing that PbCSE1 is associated with lignin deposition and stone cell formation in pear fruits. Overexpression of PbCSE1 led to increased lignin content in pear fruits and delayed growth in Arabidopsis, suggesting a potential molecular strategy to improve pear fruit quality.

Summary: This study performed phenomic analysis on stone cells and their associated vascular bundles near the pear fruit core. Transcriptomic, proteomic, and metabolomic analyses revealed the positive regulation of biological processes related to lignin deposition in stone cells near the fruit core. Moreover, a key transcription factor, PbbZIP48, was identified as a regulator of lignin biosynthesis in stone cells. These findings provide insight into the mechanism of lignified stone cell formation in pear fruit.
