“…The cell numbers of the middle mesocarp and inner mesocarp were similar, but the final cell number of the ‘O’Neal’ outer mesocarp was 1.0-fold higher than that of ‘Bluerain’, suggesting outer mesocarp was the key tissue determining fruit size variation among genotypes. In fact, the seed numbers of mature ‘O’Neal’ fruit was approximately 1.7-fold greater than those of ‘Bluerain’ fruit [ 17 ], indicating that phytohormones, which might be induced or produced by seeds, were therefore likely to promote fruit size increase, especially for mesocarp tissues [ 39 ].…”

Background Blueberry (Vaccinium spp.) is characterized by the production of berries that are smaller than most common fruits, and the underlying mechanisms of fruit size in blueberry remain elusive. V. corymbosum ‘O’Neal’ and ‘Bluerain’ are commercial southern highbush blueberry cultivars with large- and small-size fruits, respectively, which mature ‘O’Neal’ fruits are 1 ~ 2-fold heavier than those of ‘Bluerain’. In this study, the ontogenetical patterns of ‘O’Neal’ and ‘Bluerain’ hypanthia and fruits were compared, and comparative transcriptomic analysis was performed during early fruit development. Results V. corymbosum ‘O’Neal’ and ‘Bluerain’ hypanthia and fruits exhibited intricate temporal and spatial cell proliferation and expansion patterns. Cell division before anthesis and cell expansion after fertilization were the major restricting factors, and outer mesocarp was the key tissue affecting fruit size variation among blueberry genotypes. Comparative transcriptomic and annotation analysis of differentially expressed genes revealed that the plant hormone signal transduction pathway was enriched, and that jasmonate-related TIFYs genes might be the key components orchestrating other phytohormones and influencing fruit size during early blueberry fruit development. Conclusions These results provided detailed ontogenetic evidence for determining blueberry fruit size, and revealed the important roles of phytohormone signal transductions involving in early fruit development. The TIFY genes could be useful as markers for large-size fruit selection in the current breeding programs of blueberry.

“…GA promotes parthenocarpy and is widely used to produce seedless fruits in many different grape cultivars [ 27 – 29 , 79 – 81 ]. The expression patterns of GA biosynthesis- and signaling-related genes in the grape berry have been well documented [ 82 – 84 ]. Wang et al proposed that GA biosynthesis exceeds GA inactivation during the early stage of development [ 84 ].…”

Phytohormones and their interactions are critical for fruit development and, are key topics in horticulture research. Auxin, together with gibberellic acid (GA), promotes cell division and expansion, thus subsequently regulates fruit development and enlargement after fertilization. Auxin and GA related mutants show parthenocarpy (fruit formation without fertilization of ovule) in many plant species, indicating that these hormones and possibly their interactions play a key role in the regulation of fruit initiation and development. Recent studies have shown clear molecular and genetic evidence that ARF/IAA and DELLA protein interact each other and regulate both auxin and GA signaling pathways in response to auxin and GA during fruit growth in horticultural plants, tomato (the most studied freshy fruit) and strawberry (the model of Rosaceae). These recent findings provide new insights into the mechanisms by which plant hormones auxin and GA regulate fruit development.

“…Berries with/without seeds directly affect the quality of these products above, and especially, seedlessness is the much important quality trait of table berries and raisins. So far, less seedless grape cultivars are di cult to meet the needs in grape production, and thus GA were widely used to induce seedless grape berries in production (Zhang et al 2019; ; Wang et al 2020). However, the mechanism of GA-induced seedless grape berries is unclear yet.…”

GA (Gibberellin) is one key hormone of inducing grape seedless berries. VvmiR166s were revealed to be the important regulator of responding to GA in grapes, but their roles remain unclear yet. Here, the precise sequences of VvmiR166s and their potential targets VvREV, VvHB15 and VvHOX32, were determined in grape cv. ‘Rosario Bianco’. The cleavage interactions and variations of VvmiR166s:(VvHB15, VvHOX32, VvREV) were validated by RLM-RACE and PPM-RACE. Promoters cis-elements analysis supported that VvMIR166s and targets containing similar GA-related cis-elements, might play roles in responding to GA.Subsequently, spatio-temporal expression modes analysis of VvMIR166s and their targets in grape berries suggest that, almost all VvMIR166s possessed the lowest expression level at 46DAF (stone hardening stage) in seeds and peels under GA treatment except for VvMIR166h. Interestingly, their target gene VvHB15 exhibited the opposite expression, indicating that GA promoted the negative regulatory roles of VvmiR166s on VvHB15. Subsequently, over-expressions of VvMIR166b/h in Tobaccos, decreased the expression of its target VvHB15 and obviously strengthened some key genes in lignin synthesis pathway, while over-expression of VvHB15 showed the reverse regulatory modes, confirming that VvmiR166b/h might be amongst main factors of regulating lignin synthesis by mediating the expression of VvHB15. The results was deduced a key signal pathway of “GA-VvmiR166b/h-VvHB15- lignin synthesis genes”. Our findings revealed a novel insight into the roles of VvmiR166s response to GA in modulating the lignin synthesis of grape seed-stone development, which is essential for the molecular breeding of seedless grape berry.
