Thus, researchers are continually improving the agronomical traits of tomato fruits. Auxins and gibberellins regulate plant growth and development. Aux/indole-3-acetic acid 9 (SlIAA9) and the gene encoding the DELLA protein (SlDELLA) are well-known genes that regulate plant growth and development, including fruit set and enlargement by cell division and cell expansion. The absence of tomato SlIAA9 and SlDELLA results in abnormal shoot growth and leaf shape and giving rise to parthenocarpy. To investigate the key regulators that exist up- or downstream of SlIAA9 and SlDELLA signaling pathways for tomato growth and development, we performed gene co-expression network analysis by using publicly available microarray data to extract genes that are directly connected to the SlIAA9 and SlDELLA nodes, respectively. Consequently, we chose a gene in the group of heat-shock protein (HSP)70s that was connected with the SlIAA9 node and SlDELLA node in each co-expression network. To validate the extent of effect of SlHSP70-1 on tomato growth and development, overexpressing lines of the target gene were generated. We found that overexpression of the targeted SlHSP70-1 resulted in internode elongation, but the overexpressing lines did not show abnormal leaf shape, fruit set, or fruit size when compared with that of the wild type. Our study suggests that the targeted SlHSP70-1 is likely to function in shoot growth, like SlIAA9 and SlDELLA, but it does not contribute to parthenocarpy as well as fruit set. Our study also shows that only a single SlHSP70 out of 25 homologous genes could change the shoot length.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"143-153"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0603a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43053378","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 remains unclear how natural variation of plants could contribute to metabolic changes under various growth conditions. Here, we investigated the developmental and metabolomic responses of two natural accessions of Arabidopsis thaliana, Columbia (Col) and C24, and their reciprocal F1 hybrids grown under four carbon source regimens, i.e., two different photoperiods and the presence or absence of exogenous Suc supply. The effect of exogenous Suc clearly appeared in the growth of Col and the F1 hybrid but not in C24, whereas long-day conditions had significant positive effects on the growth of all lines. Comparative metabolite profiling of Col, C24, and the F1 hybrid revealed that changes in metabolite levels, particularly sugars, were highly dependent on genotype-specific responses rather than growth conditions. The presence of Suc led to over-accumulation of seven metabolites, including four sugars, a polyamine, and two amino acids in C24, whereas no such accumulation was observed in the profiles of Col and the F1 hybrid. Thus, the comparative metabolite profiling revealed that the two parental lines of the hybrid show a distinct difference in sugar metabolism.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"155-165"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0604a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43190613","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}

Hirtae) and T. macranthopsis (sect. Brachycyrtis). After cross-pollination, ovary enlargement was observed only when T. macranthopsis was used as a pollen parent. Ovules with placental tissues were excised from enlarged ovaries and cultured on half-strength MS medium without plant growth regulators. From five cross-combinations, 31 ovule culture-derived plantlets were obtained and 20 of them were confirmed to be intersectional hybrids by flow cytometry and inter-simple sequence repeat analyses. Almost all hybrids grew well and produced flowers 1-2 years after transplantation to the greenhouse. Hybrids had semi-cascade-type shoots, which was intermediate between T. formosana cultivars and T. hirta var. albescens (erect-type shoots) and T. macranthopsis (cascade-type shoots). They produced flowers with novel forms and colors compared with the corresponding parents, and some were horticulturally attractive.

In wild-type rice, a spikelet only produces one fertile floret and beneath the floret are a pair of sterile lemmas and a pair of rudimentary glumes. This study characterized a rice spikelet mutant nonstop glumes 2 (nsg2). In the nsg2 mutant, both the sterile lemmas and rudimentary glumes were elongated, and part of sterile lemma looked like a lemma in appearance, shape and size. Detailed histological analysis and qPCR analysis revealed that the sterile lemmas in the nsg2 mutant had homeotically transformed into lemma-like organs. This phenotype indicates that NSG2 is involved in the regulation of spikelet development and supports the long-held view that sterile lemmas were derived from the lemmas of the two lateral florets. This implies that the rice spikelet has the potential to be restored to the \"three florets spikelet\", which may have existed in its ancestors. Genetic analysis reveals that the nsg2 trait is controlled by a single recessive gene. The NSG2 gene was finally mapped between markers R-20 and R-39 on chromosome 7 with a physical region of 180 kb. The two MYB family factors LOC_Os07g44030 and LOC_Os07g44090 might be involved in the development of the spikelet and floral organ, and they were considered as candidate genes of NSG2. These results provide a foundation for map-based cloning and function analysis of NSG2, as well as evidence to support \"three-florets spikelet\" breeding in rice.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 3 1","pages":"125-134"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0506a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49060690","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}

The CRISPR/Cas9 system is widely used as a tool for targeted gene editing in many organisms including plants. Previously, we established a transient gene expression system for investigating cellular circadian rhythms in duckweed. In this system, circadian reporters and clock gene effectors-such as overexpressors, RNA interference (RNAi), and CRISPR/Cas9-were introduced into duckweed cells using a particle bombardment method. In the present study, we applied the CRISPR/Cas9 system at a single cell level to Arabidopsis thaliana, a model organism in plant biology. To evaluate the mutation induction efficiency of the system, we monitored single-cell bioluminescence after application of the CRISPR/Cas9 system targeting the ELF3 gene, which is essential for robust circadian rhythmicity. We evaluated the mutation induction efficiency by determining the proportion of cells with impaired circadian rhythms. Three single guide RNAs (sgRNAs) were designed, and the proportion of arrhythmic cells following their use ranged from 32 to 91%. A comparison of the mutation induction efficiencies of diploid and tetraploid Arabidopsis suggested that endoreduplication had a slight effect on efficiency. Taken together, our results demonstrate that the transiently introduced CRISPR/Cas9 system is useful for rapidly assessing the physiological function of target genes in Arabidopsis cells.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"104 5","pages":"187-193"},"PeriodicalIF":1.6,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/plantbiotechnology.19.0531a","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41297367","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}

The present review will overview the principles of colorimetry, and will introduce colorimetric methods which can be used for scientific measurement of plant colors. That is to say, the reflection spectrum of visible light (380-780 nm) is measured at 5-nm intervals on the surface of leaves or petals in 'Spectrometric Color Measurement' (SCM). The spectral data is multiplied with RGB or XYZ color matching functions and integrated to obtain RGB or XYZ intensities. Alternatively, approximate RGB values are directly obtained in 'Photographic Color Measurement' (PCM). RGB/XYZ intensities are further calculated to obtain 'hue', 'saturation', and 'lightness', the three factors of colors. Colorimetric insights into genetic regulations (such as MYB gene) and physiological regulations (such as alexandrite effect) of plant colors are also described.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 2 1","pages":"63-75"},"PeriodicalIF":1.6,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/PLANTBIOTECHNOLOGY.19.0322A","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43576237","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}

The Arabidopsis Tóxicos en Levadura (ATL) family is a group of plant-specific RING-type ubiquitin ligases with N-terminal transmembrane-like domains. To date, 91 ATL isoforms have been identified in the Arabidopsis genome, with some reported to regulate plant responses to environmental stresses. However, the functions of most ATLs remain unclear. This study showed that ATL8 is a sugar starvation response gene and that ATL8 expression was significantly increased by sugar starvation conditions but repressed by exogenous sugar supply. The ATL8 protein was found to possess ubiquitin ligase activity in vitro and to localize to membrane-bound compartments in plant cells. In addition, Starch Synthase 4 was identified as a putative interactor with ATL8, suggesting that ATL8 may be involved in modulating starch accumulation in response to sugar availability. These findings suggest that ATL8 functions as a membrane-localized ubiquitin ligase likely to be involved in the adaptation of Arabidopsis plants to sugar starvation stress.","PeriodicalId":20411,"journal":{"name":"Plant Biotechnology","volume":"36 2 1","pages":"107-112"},"PeriodicalIF":1.6,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5511/PLANTBIOTECHNOLOGY.19.0328A","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47498134","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}
