However, its role in the regulation of grapevine development is still unclear. In order to explore the function of VvBMI1a gene in the regulation of flowering in Vitis vinifera ‘Cabernet Sauvignon’, the subcellular localization, expression pattern, yeast two-hybrid, two-molecule fluorescence complementation and flowering time of transgenic Arabidopsis were analyzed. The results showed that VvBMI1a, a member of RING domain-containing proteins family from grapevine (Vitis vinifera), is involved in controlling plant flowering time. Expression of VvBMI1a was abundant in the shoot tips and inflorescence meristems of grapevine. VvBMI1a protein is localized in the nucleus. VvBMI1a could interact with VvRING1a protein which belonged to PRC1. Phenotypic analysis showed that VvBMI1a over-expression lines had earlier flowering time than wild-type plants under long-day (LD) conditions. Further analysis by qRT-PCR and transcriptome suggests that both the suppression of FLC and activation of FT, SOC1, SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 5 (SPL5), AGL8 were observed in VvBMI1a-overexpressing lines, resulting in early flowering. Our results provide the evidence demonstrating the effectiveness of manipulating VvBMI1a to alter the flowering time of plants. In a word, ectopic overexpression of VvBMI1a inhibited the expression of FLC, activated the expression of FT, SPL5, AGL8 to alter the flowering time of Arabidopsis plants.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":"25 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140884516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the defense elicitor effect of both low (0.05 W/cm2) and high (0.133 W/cm2) powered UV-C (275 nm) against Botrytis cinerea on grapevines. Gene expression, total stilbene content, and the quality of the berries were assessed in ‘Kyoho’ grapevines irradiated with UV-C. Low and high-powered UV-C reduced the in vitro growth of B. cinerea by 40–50% and lowered the in vivo infection and disease severity by 40–85% in the leaves. Lesion formation was reduced by 20–50% in berries treated with UV-C. The spores of B. cinerea did not infect the unwounded berries of ‘Shine Muscat’ and ‘Kyoho’ grape treated with UV-C. The augmented levels of total soluble solids, color values, and reduced titratable acidity improved the quality of the UV-C-irradiated ‘Kyoho’ berries compared to the control. The total stilbene content was four to five times higher with 37.48 µg g−1 fresh weight (FW) using low UV-powered UV-C and 43.11 µg g−1 FW using high UV-powered UV-C in ‘Kyoho’ berry skins treated with UV-C compared to the control (9.24 µg g−1 FW), with predominant levels of trans-resveratrol. The genes involved in stilbene synthesis, defense, and antioxidant activity were strongly upregulated in the leaves and berries of grapevines in response to the low and high UV-C treatments. The low and high UV-C treatments elicit the induction of resistances in grapes against B. cinerea and improve the quality of berries. Future research will be needed on other parameters before UV-C irradiation can be applied to inhibit the incidence of grey mold in vineyards.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":"14 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140613404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agar (15 g L− 1) was added to a soil mixture, which comprised potting soil, perlite, fertilizer, and water, to semi-solidify it into a substrate block. Lettuce seeds were sown in the semi-solidified substrate, which was prepared in a custom-made, enclosed container with planting holes in the lid. Three different soil-to-water (SW) ratio (v:v) treatments were used to prepare the soil substrate: SW1:1; SW1:2; SW2:1, and three fertilizer treatments were tested: no fertilizer (control); urea; NPK (15:3:3) fertilizer. Results showed that the semi-solidified soil substrates can be used to successfully grow lettuce for 28 days, however, the extent of their growth varied depending on the soil-water ratio and fertilizer treatment. Lettuce plants grown in the NPK-enriched SW2:1 substrate had significantly higher number of leaves, leaf area, and dry weight compared to all the other treatments. In contrast, the lettuce plants grown without additional fertilizers exhibited poor growth regardless of the soil-water ratio used. In the growing substrates supplemented with urea, the SW1:2 ratio treatment produced lettuces with the lowest leaf number, leaf area, leaf fresh weight, and dry weight. Overall, the chlorophyll a/b ratio and Fv/Fm value of lettuces grown in substrate fertilized with NPK were found to be higher than all the other treatments. The key feature of this cultivation method was the use of agar to semi-solidify the waterlogged soil mixture and transform it into a growing substrate that provided the necessary water and nutrients for plant growth over a 28-day period. The growing substrate developed in this study, which is the first of its kind, can be considered as a new soil-based method of growing lettuce indoors.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":"1 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140578619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rootstocks provide roots for grafted fruit trees. The rootstocks absorb water and mineral nutrients and affect the growth and development of the tree and the quality of fruit and its yield. Furthermore, the appropriate rootstock for drought conditions is key to the sustainable production of apple (Malus spp.). Chistock #1 is a new semi-dwarfing apple rootstock. The drought tolerance of Chistock #1 was compared with that of M9, M26 and M. prunifolia through pot and field experiments. In pot experiments, drought tolerant rootstocks were selected by comparing the root configuration, leaf anatomical structure, electrical conductivity and SPAD value. The results showed that the roots of Chistock #1 and M. prunifolia were long and well developed. Under drought stress, M. prunifolia can close its stomata in time to reduce water loss, followed by Chistock #1 and M26, while M9 was the slowest at closing its stomata. After drought treatment, the leaf and palisade tissue thickness and SPAD value of Chistock #1 were the highest at 121.56 μm, 42.03 μm and 43.00 μm, respectively. The fruit yield and quality of different scion and rootstock combinations were measured in field experiments. A Fuji scion cultivar grafted to Chistock #1 had a higher yield and better quality as determined by its suitable ratio of total soluble solids and titratable acid. Finally, a membership function combined with a principal component analysis was used to comprehensively evaluate the drought tolerance of the four rootstocks. The results were as follows: Chistock #1 was the most drought tolerant of the four rootstock genotypes, M. prunifolia and M26 were the second and third most drought tolerant rootstocks, while M9 was the least drought tolerant.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":"33 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140578828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two tomato cultivars H2274 and Galaxy were grafted onto three S. pimpinellifolium, three S. habrochaites, S. lycopersicum L. × S. pimpinellifolium and S. lycopersicum L. × S. Habrochaites hybrid tomato genotypes. Plants were grown in hydroponic culture at two electrical conductivity (EC) levels (control at 1.5 dSm-1 and salt at 8.0 dSm-1). Salt stress led to a significant reduction in biomass growths of both grafted and nongrafted tomatoes. However, the plants that are least affected by salt stress are those grafted on wild tomato rootstocks. Leaf nutrient contents were significantly affected by rootstocks under both control and salt stress conditions. In this study, under saline conditions, plants grafted on wild rootstocks had higher N, P, K, Ca, Mg, S, Mn, Fe, Zn and B contents in leaf tissues and lower Na and Cl contents than ungrafted plants. Biochemical and physiological results revealed that S. pimpinellifolium and S. habrochaites have inherited salt tolerance from their genetic background. These wild tomato genotypes can be used as rootstocks in tomato breeding programs to develop salt-tolerant tomatoes or in grafting techniques under saline irrigation conditions.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":"45 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140578879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
