“…Cucumber (Cucumis sativus L.) is a globally important vegetable in the Cucurbitaceae family. It is a typical cold-sensitive vegetable with important economic and nutritional value [54]. In recent years, cucumber has achieved continuous annual production, and the planting area for cultivation has expanded.…”

Cold tolerance is improved by cold stress acclimation (CS-ACC), and the cold tolerance level is ‘remembered’ by plants. However, the underlying signaling mechanisms remain largely unknown. Here, the CS memory mechanism was studied by bioinformation, plant physiological and photosynthetic parameters, and gene expression. We found that CS-ACC induced the acquisition of CS memory and enhanced the maintenance of acquired cold tolerance (MACT) in cucumber seedlings. The H2O2 content and NADPH oxidase activity encoded by CsRBOH was maintained at higher levels during recovery after CS-ACC and inhibition of RBOH-dependent signaling after CS-ACC resulted in a decrease in the H2O2 content, NADPH oxidase activity, and MACT. CsRBOH2, 3, 4, and 5 showed high expression during recovery after CS-ACC. Many BZR-binding sites were identified in memory-responsive CsRBOHs promoters, and CsBZR1 and 3 showed high expression during recovery after CS-ACC. Inhibition of RBOH-dependent signaling or brassinosteroids affected the maintenance of the expression of these memory-responsive CsRBOHs and CsBZRs. The photosynthetic efficiency (PE) decreased but then increased with the prolonged recovery after CS-ACC, and was higher than the control at 48 h of recovery; however, inhibition of RBOH-dependent signaling resulted in a lower PE. Further etiolated seedlings experiments showed that a photosynthetic capacity was necessary for CS memory. Therefore, photosynthesis mediated by RBOH-dependent signaling is essential for CS memory.

“…Cucumber ( Cucumis sativus L.) is an economically important vegetable crop worldwide, which has the unique growth habit and shoot architecture of Cucurbitaceae [ 1 , 2 , 3 , 4 ]. The vegetative and reproductive growth of cucumber proceed simultaneously after a very short juvenile stage [ 5 , 6 , 7 ].…”

“…In addition, some of the genes related to growth and development were identified by means of reverse genetics in cucumber. There have been about 25 genes reported as being involved in shoot architecture of cucumber, including determinate growth habit ( CsTFL1 and CsLFY ), leaf morphology ( CsPID , CsWOX1 , CsIVP , CsYAB5 , CsPHB , CsSAP , CsSL1 , and CsHAN1 ), lateral branching ( CLS , CsBRC1 , and CsPIN3 ), tendril formation ( CsTEN , CsACO1 , CsGCN5 , and CsPID ), and vine length ( CsSH1 , CsGPA1 , CsCLV1 , CsCKX , CsCullin1 , CsCYP85A1 , CsDET2 , CsVFB1 , CsIVP , and CsYAB5 ) [ 3 ]. Although a large number of developmental mutants has been reported and some candidate genes related to plant development cloned, the molecular mechanisms underlying plant growth and development in cucumber remains unclear.…”

Cucumber (Cucumis sativus L.) is an economically important vegetable crop with the unique growth habit and typical trailing shoot architecture of Cucurbitaceae. Elucidating the regulatory mechanisms of growth and development is significant for improving quality and productivity in cucumber. Here we isolated a spontaneous cucumber mutant organ development defective 1 (odd1) with multiple morphological changes including root, plant stature, stem, leaf, male and female flowers, as well as fruit. Anatomical and cytological analyses demonstrated that both cell size and number decreased, and the shoot apical meristem (SAM) was smaller in odd1 compared with WT. Pollen vigor and germination assays and cross tests revealed that odd1 is female sterile, which may be caused by the absence of ovules. Genetic analysis showed that odd1 is a recessive single gene mutant. Using the MutMap strategy, the odd1 gene was found to be located on chromosome 5. Integrated profiling of transcriptome and proteome indicated that the different expression genes related to hormones and SAM maintenance might be the reason for the phenotypic changes of odd1. These results expanded the insight into the molecular regulation of organ growth and development and provided a comprehensive reference map for further studies in cucumber.

“…Plant architecture-e.g. the number of branches-determines yield (whether fruit or flowers) in many horticultural species (Bredmose, 1993;Liu et al, 2021). It also defines the visual quality of potted ornamental plants by determining their shape (Boumaza et al, 2009;Garbez et al, 2015).…”

Plant architecture determines yield (fruit or flowers) and product quality in many horticultural species. It results from growth and branching processes and is dependent on genetic and environmental factors such as light quality. Highly significant genotype and light quality effects and their interaction have been demonstrated on the architecture of rose. Far-red (FR) light is known for its favourable effect on plant growth and development. We evaluated the effect of FR on rose growth and development and its interaction with the genotype through architectural, eco-physiological (net photosynthesis rate) and biochemical (sugar and hormone concentrations) approaches. Two cultivars (‘The Fairy’ – TF – and Knock Out® Radrazz – KO) with contrasting architectures were grown in a climate chamber under FR or in the absence of FR at an average photosynthetic photon flux density (400–700 nm) of 181.7 ± 12.8 μmol m−2 s−1 for 16 h. A significant effect of FR on the architecture of TF was demonstrated, marked by greater stem elongation, shoot branching and flowering, while KO remained insensitive to FR, supporting a genotype x FR interaction. The response of TF to FR was associated with improved photosynthetic capabilities, while KO exhibited an elevated level of abscisic acid (ABA) in its leaves. FR-dependent ABA accumulation might inhibit photosynthesis and prevent the increased plant carbon status required for growth. From a practical perspective, these findings argue in favour of a better reasoning of the choice of the cultivars grown in lighted production systems. Further investigations will be necessary to better understand these genotype-specific responses to FR and to unravel their molecular determinants.
