“…Nonetheless, only TFs have been reported as regulators for the establishment of the lignification pattern. However, in similar abscission processes occurring in the floral organ abscission zone (reviewed by Niederhuth et al ., 2013) or silique dehiscence zone (reviewed by Yu et al ., 2020), several intervenients besides TFs have been reported: hormones (like ethylene, auxin, jasmonic acid), small peptides and their receptors (INFLORESCENCE DEFICIENT IN ABSCISSION is perceived by HAESA or HAESA-LIKE 1), as well as cell wall modifying enzymes (cellulases, hemicellulases and pectinases).…”

In Angiosperms, the continuation of plant species is intricately dependent on the funiculus multifaceted role in nutrient transport, mechanical support, and dehiscence of seeds. SEEDSTICK (STK) is a MADS-box transcription factor involved in seed size and dehiscence, and one of the few genes identified as affecting funiculus growth. Given the importance of the funiculus to a correct seed development, allied with previous phenotypic observations ofstkmutants, we performed a transcriptomic analysis ofstkfuniculi, using RNA-sequencing, to infer on the deregulated networks of genes. The generated dataset of differentially expressed genes was enriched with cell wall biogenesis, cell cycle, sugar metabolism and transport terms, all in accordance withstkphenotype. We selected eight differentially expressed genes involved with abscission, seed development or novel functions instkfuniculus, such as hormones/secondary metabolites transport, for transcriptome validation using qPCR and/or promoter reporter lines. Overall, the analysis performed in this study allowed delving into the STK-network established in Arabidopsis funiculus, fulfilling a literature gap. Simultaneously, our findings reinforced the reliability of the transcriptome, and identified processes and new candidate genes that will enable a better understanding on the role of this sporophytic structure and how seed development may be affected by it.

“…Fruit dehiscence is a critical process for seed dispersal affecting the completion of the propagation cycle of many plant species, and is tightly associated with yield losses in agriculture. Preharvest fruit dehiscence causes seeds to be shed before or during harvest, bringing substantial yield losses [ 1 , 2 ]. Conversely, delayed dehiscence is not conducive to harvesting, and the accumulation of dry matter or desired components will be reduced or changed due to the respiration of seeds [ 2 ].…”

Conversely, delayed dehiscence is not conducive to harvesting, and the accumulation of dry matter or desired components will be reduced or changed due to the respiration of seeds [ 2 ]. The dehiscing process of fruit has been well studied in plants of legumes and crucifers, such as soybean, Arabidopsis thaliana ( A. thaliana ), and Brassica napus ( B. napus ) [ 1 , 3 ].…”

“…The legume pod has a single seed-attaching carpel and lacks a replum [ 4 ]. By contrast, the fruit of rapeseed and Arabidopsis share multiple similarities in the shattering process, as well as a similar silique structure [ 2 , 5 ], which consists of two fused valves (carpels), connected with the replum [ 4 ].…”

“…The dehiscence zone (DZ), a common and important structure, occurs along the edge between the valves, or the valve and the replum, and mediates the indehiscence or dehiscence of matured fruit. An abnormal phenotype of fruit dehiscence is usually accompanied by special tissue morphology of the DZ, including developmental defects [ 2 , 6 ]. The cell separation process in the DZ, enabling fruit dehiscence, is coordinately controlled by multiple regulators.…”

Camellia oleifera (C. oleifera), one of the world’s four major edible woody oil crops, has been widely planted in southern China’s subtropical region for the extremely high nutritional and health benefits of its seed oil. Timing and synchronization of fruit dehiscence are critical factors influencing the oil output and quality, as well as the efficiency and cost of harvesting C. oleifera, yet they extremely lack attention. To gain an understanding of the molecular basis underlying the dehiscence of C. oleifera fruit, we sampled pericarp–replum tissues containing dehiscence zones from fruits at different developmental stages and performed time-series transcriptomic sequencing and analysis for the first time. Statistical and GO enrichment analysis of differentially expressed genes revealed that drastic transcriptional changes occurred over the last short sampling interval (4 days, 18th–22nd October), which directed functional classifications link to cell wall and cell wall macromolecule activity. WGCNA further showed that factors controlling cell wall modification, including endo-1,3;1,4-beta-D-glucanase, WAT1-like protein 37, LRR receptor-like serine/threonine-protein kinase, and cellulose synthase A catalytic subunit, were identified as core members of the co-expression network of the last stage highly related modules. Furthermore, in these modules, we also noted genes that were annotated as coding for polygalacturonase and pectinesterase, two pectinases that were expected to be major players in cell separation during dehiscence. qRT-PCR further confirmed the expression profiles of these cell wall modification relating factors, which possessed a special high transcriptional abundance at the final stage. These results suggested the cell wall associated cell separation, one of the essential processes downstream of fruit dehiscence, happened in dehiscing fruit of C. oleifera during ripening. Hydrolases acting on cell wall components are good candidates for signal mediating dehiscence of C. oleifera fruit. In conclusion, our analysis provided insights into the cell wall macromolecule-mediated fruit dehiscence during ripening in C. oleifera.
