Recent transcriptome analyses reveal that expression of a population of salinity-inducible genes also exhibits circadian rhythms. However, since the analyses were performed independently from those with salinity stress, it is unclear whether the observed circadian rhythms simply represent their basal expression levels independently from their induction by salinity, or these rhythms demonstrate the function of the circadian clock to actively limit the timing of occurrence of the salinity induction to particular times in the day. Here, by using tomato, we demonstrate that salt inducibility in expression of particular salinity-stress related genes is temporally controlled in the day. Occurrence of salinity induction in expression of SlSOS2 and P5CS, encoding a sodium/hydrogen antiporter and an enzyme for proline biosynthesis, is limited specifically to the morning, whereas that of SlDREB2, which encodes a transcription factor involved in tomato responses to several abiotic stresses such as salinity and drought, is restricted specifically to the evening. Our findings not only demonstrate potential importance in further investigating the basis and significance of circadian gated salinity stress responses under fluctuating day/night conditions, but also provide the potential to exploit an effective way for improving performance of salinity resistance in tomato.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"195-200"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0703a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47827325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is generally difficult to breed a new variety of potato crops because they are highly heterozygous tetraploid. Steroidal glycoalkaloids (SGAs) such as α-solanine and α-chaconine found in potato are antinutritional specialized metabolites. Because of their toxicity following intake, controlling the SGA levels in potato varieties is critical in breeding programs. Recently, genome-editing technologies using artificial site-specific nucleases such as TALEN and CRISPR-Cas9 have been developed and used in plant sciences. In the present study, we developed a highly active Platinum TALEN expression vector construction system, and applied to reduce the SGA contents in potato. Using Agrobacterium-mediated transformation, we obtained three independent transgenic potatoes harboring the TALEN expression cassette targeting SSR2 gene, which encodes a key enzyme for SGA biosynthesis. Sequencing analysis of the target sequence indicated that all the transformants could be SSR2-knockout mutants. Reduced SGA phenotype in the mutants was confirmed by metabolic analysis using LC-MS. In vitro grown SSR2-knockout mutants exhibited no differences in morphological phenotype or yields when compared with control plants, indicating that the genome editing of SGA biosynthetic genes such as SSR2 could be a suitable strategy for controlling the levels of toxic metabolites in potato. Our simple and powerful plant genome-editing system, developed in the present study, provides an important step for future study in plant science.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"167-173"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0805a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41865370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transgenic white Oncidium orchids, Honey Snow MF-1, have been grown to test their genetic stability, and their environmental biosafety was assessed for approximately one year under government regulatory instructions from the Council of Agriculture, Taiwan. In the present study, pollen sterility was demonstrated by cytological observation of the microsporogenesis step, pollen morphology abortion, and failure of pollen germination.

Anise somatic embryos are also induced even if embryogenic callus is continually cultured in 2,4-D-containing medium without subculturing. In this study, we aimed to clarify the dynamics of 2,4-D during anise cell culture. After culturing anise callus in 2,4-D-containing medium, 2,4-D in the medium was analyzed by thin-layer chromatography. In the medium, 2,4-D was decreased during anise callus culture, and fully abolished after 5-day culture. On the other hand, no decrease in 2,4-D was observed in the other Apiaceae species (carrot, fennel, dill, parsley, and coriander). After 7-day culture of anise callus, the medium was collected following removal of the cultured cells and 2,4-D was added to the collected medium. After 10 days of incubation and shaking, 2,4-D was markedly decreased in the medium. However, when the collected medium was heat-treated at 100°C, 2,4-D was detected after 20 days of incubation. Therefore, anise callus has a specific 2,4-D degradation system, in which heat-inactivated secreted molecules may participate.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"209-212"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0805b","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42226240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
