Fruit from papaya cultivated using raised bed conditions were crisper than those cultivated under open field conditions. Conversely, fruit cultivated under open field conditions were firmer. In all cases, mesocarp cells and intercellular spaces were larger in papaya fruit cultivated in raised beds, reflecting the higher relative humidity (RH) of the cultivation conditions and greater water availability. At harvest, TIP2–1, TIP4–1, SIP1 and PIP1–3 expression was significantly higher in fruit cultivated under raised bed conditions, which correlated with the larger cells of the mesocarp, the RH and the ready availability of water. There also appeared to be a link between aquaporin gene expression and crispness in papaya fruit from both conditions. Expression of TIP2–1 and TIP4–1 correlated with papaya fruit under open field conditions while SIP1 and PIP2–5 correlated with papaya fruit under raised bed conditions. The results clearly demonstrate the effect of cultivation conditions on fruit texture, with water availability being critical in the production of market-preferred crisp fruit with the optimal conditions. These conditions are reflected in the higher expression of the water transport aquaporins which likely control crispness.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"23 1","pages":"758 - 771"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83246942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the timeframe estimated for plantlet production is underestimated resulting in exceptionally long processes in the laboratory that make the production system unfeasible to bring to markets. Somatic embryogenesis (SE) is considered the most suitable and integrated technology for the large-scale production of clonal cocoa plants, compared to conventional methods. To date, practical application of SE to produce cocoa genotypes of interest has been limited, and for ‘drop-in’ technology replacements, price is of paramount importance for success. Therefore, the objective of this work was to produce the CCN51 genotype in a pilot scale in the laboratory with an approach to commercial production. The productive stages for a complex biological process such as SE and a reduction in production cycle time were defined. The production stages defined for SE were initiation, multiplication, maturation, germination, and acclimatization. The minimal time obtained for CCN51 production was 8.3 months: 30, 70, 50, 70, and 30 days, respectively. The decrease in the time of the production process directly influences the process cost and it represents a breakthrough in the technology development.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"5 1","pages":"814 - 826"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75754671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the mangosteen crop, these losses are all the more important as they constitute a major problem. In Côte d’Ivoire, the few mangosteen preservation techniques have been developed mainly by traders and are based on limiting exchanges with the surrounding environment. However, these techniques are not very effective because they only preserve the fruit for a few days. In order to address this issue, the present study aims to evaluate the influence of the harvesting stage and the effectiveness of preservation treatments on the storage time and the evolution of several physical and biochemical parameters of the mangosteen. To this end, mangosteens harvested at two different stages of maturity were subjected to different preservation treatments (refrigeration, bagging, oil coating and blanching). The results showed that the storage time of the mangosteen was significantly longer with fruit harvested at the orange-red stage. Also, two of the four storage treatments evaluated, namely refrigeration and bagging, significantly extended the shelf life of the mangosteen (+15 and+6 days respectively with these treatments). In contrast to these treatments, blanching caused a reduction in fruit storage time.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"79 1","pages":"786 - 798"},"PeriodicalIF":0.0,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83927894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its nutraceutical properties have increased demand in global markets. However, coconut productivity remains low owing to inadequate improved planting materials. This challenge has created a high demand and low supply gap in the coconut industry, which needs to be addressed through breeding methods that can increase productive cultivars in a shorter time. Breeding methods, such as mass selection and hybridization between dwarf and tall cultivars, are the main coconut improvement methods because of their simplicity and ease of use. The hybrids produced, however, take a long time (4-6 years) to bear fruits due to genes inherited from tall parents. Dwarf hybrids that bear fruits in a shorter time (3 years) are less exploited. Developing these coconut types through efficient breeding methods can fill the supply and demand gaps created in the coconut industry. Marker-assisted selection and multi-omics, have been used to identify quantitative traits of agronomic importance to increase genetic gains in dwarf coconut cultivars. This review article summarizes the advances in coconut improvement through conventional breeding, marker-assisted selection, and multi-omics approaches, focusing on dwarf coconut cultivars.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"119 1","pages":"551 - 562"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76119165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying the molecular mechanism of auxin regulation in growth is of great significance for enhancing the understanding of the growth and development processes in rose and informing accurate exogenous auxin application in rose production. However, the response mechanism of rose to miRNA-mediated auxin signal transduction is unclear. In this study, rose plants were treated with IAA, and 75 known miRNAs and 168 novel miRNAs were identified by small RNA sequencing. Among them, 19 known miRNAs and 42 miRNAs were differentially expressed. Many differential miRNAs demonstrated staged responses to auxin treatment. The targeted relationship between miRNA and key transcription factors regulated by auxin in rose was analysed, and the target genes in the ARF family and AUX/IAA family were screened. By using quantitative real-time PCR(qRT-PCR) to verify the expression patterns of the miRNA regulating the auxin signal transduction pathway and its target gene, we found that miR156a, miR160a, miR164a, miR167d, miR396b-3p, novel_miR_189, novel_miR_74, novel_miR_8, and novel_miR_207 were anti-correlated with the ARF family, and miR390a-3p and novel_miR_101 were anti-correlated with the AUX/IAA family.

Tetraploid (4×) plants are more adaptable to environmental constraints than diploid (2×) plants by inducing critical physiological and biochemical processes. In this study, tetraploid and their corresponding diploid sour orange rootstocks were subjected to drought stress for 12 days. Results revealed that drought stress significantly affected plant physiology by reducing photosynthesis rate, stomatal conductance, transpiration rate, and leaf colour, which was prominent in diploid plants compared to tetraploid plants. In diploid plants, phenotypic differences (i.e. wilting and rolling of leaves) were also significant. Diploids with more accumulation of malondialdehyde and hydrogen peroxide in their leaves and roots exhibited more oxidative damage. It was observed that tetraploid plants had higher activities of peroxidase and catalase enzymes, while lower superoxide dismutase was recorded in the leaves and roots of plants. Higher glycine betaine, proline, total soluble protein, total phenolic content, and antioxidant activities were also observed in the leaves and roots of tetraploids. Overall, results suggest that tetraploids in citrus can have better defence mechanisms that help them to sustain under water deficit scenarios.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"6 1","pages":"772 - 785"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78775457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solms can absorb nitrogen and phosphorus efficiently from water. Cloning the phosphate transporter 1 from E. crassipes (EcPHT1) and studying its characteristics can help to explain the molecular mechanism of absorption and transportation of inorganic phosphate (Pi) in E. crassipes and develop new genetic resources for phosphate transport to aid genetic breeding of crops with increased phosphate use efficiency. In this paper, we have used RACE method to clone the EcPT1 with 1572 bps which encoded a polypeptide of 523 amino acids and contained 11 transmembrane regions which was the typical structure of plant PHT1. The phylogenetic analysis also showed EcPT1 was closely related to other plant PHT1s. Quantitative real-time RT-PCR (qRT-PCR) showed that the EcPT1 expression in roots was up-regulated under low phosphorus stress . Moreover the EcPT1 expression in leaves was suppressed after E. crassipes was transferred to sufficient Pi from deficient Pi. Yeast functional complementation tests showed that the EcPT1 could complement the phosphate transport function of the Pi deficient yeast PHO84 in 175 μM Pi and make it grow best in pH = 5 or 6. All these results indicated that EcPT1 might be a phosphate transporter gene. Its expression was different in different tissues.","PeriodicalId":22704,"journal":{"name":"The Journal of Horticultural Science and Biotechnology","volume":"37 1","pages":"580 - 590"},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85609481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
