Abstract Chrysanthemum ( morifolium Ramat.) is a leading flower with applied value worldwide. Developing new chrysanthemum cultivars novel characteristics such as colors and shapes, plant architectures, flowering times, postharvest quality, biotic abiotic stress tolerance in time- cost-efficient manner the ultimate goal for breeders. Various breeding strategies have been employed to improve aforementioned traits, ranging from conventional techniques, including crossbreeding mutation breeding, series of molecular methods, transgenic technology, genome editing, marker-assisted selection (MAS). In addition, recent extensive advances high-throughput technologies, especially genomics, transcriptomics, proteomics, metabolomics, microbiomics, which are collectively referred omics platforms, led collection substantial amounts data. Integration these data phenotypic information will enable identification genes/pathways responsible important traits. Several attempts made use emerging methods aim accelerating chrysanthemum. However, applying findings studies practical remains considerable challenge, primarily due high heterozygosity polyploidy species. This review summarizes achievements modern technologies discusses their future applications improving agronomic horticultural

Transgenic Breeding Approaches for Improving Abiotic Stress Tolerance: Recent Progress and Future Perspectives

International Journal of Molecular Sciences, Год журнала: 2020, Номер 21(8), С. 2695 - 2695

Опубликована: Апрель 13, 2020

The recent rapid climate changes and increasing global population have led to an increased incidence of abiotic stress decreased crop productivity. Environmental stresses, such as temperature, drought, nutrient deficiency, salinity, heavy metal are major challenges for agriculture, they lead a significant reduction in growth Abiotic is very complex phenomenon, involving variety physiological biochemical plant cells. Plants exposed exhibit enhanced levels ROS (reactive oxygen species), which highly reactive toxic affect the biosynthesis chlorophyll, photosynthetic capacity, carbohydrate, protein, lipid, antioxidant enzyme activities. Transgenic breeding offers suitable alternative conventional achieve genetic improvements. Over last two decades, engineering/transgenic techniques demonstrated remarkable developments manipulations genes induction desired characteristics into transgenic plants. approaches provide us with access identify candidate genes, miRNAs, transcription factors (TFs) that involved specific processes, thus enabling integrated knowledge molecular mechanisms influencing tolerance accuracy precision this phenomenon assures great success future Hence, has proven be promising tool improvement crops. This review focuses on potential successful applications, progress, perspectives improving productivity

Application of the CRISPR/Cas9 system for modification of flower color in Torenia fournieri

BMC Plant Biology, Год журнала: 2018, Номер 18(1)

Опубликована: Дек. 1, 2018

CRISPR/Cas9 technology is one of the most powerful and useful tools for genome editing in various living organisms. In higher plants, system has been widely exploited not only basic research, such as gene functional analysis, but also applied research crop breeding. Although used to induce mutations genes involved plant developmental processes, few studies have performed modify color ornamental flowers. We therefore attempted use this flower model torenia (Torenia fournieri L.). flavanone 3-hydroxylase (F3H) gene, which encodes a key enzyme flavonoid biosynthesis. Application successfully generated pale blue (almost white) flowers at high frequency (ca. 80% regenerated lines) transgenic T0 plants. Sequence analysis PCR amplicons by Sanger next-generation sequencing revealed occurrence base substitutions insertions/deletions F3H target sequence, thus indicating that obtained phenotype was induced targeted mutagenesis endogenous gene. These results clearly demonstrate modification with easily efficiently achievable. Our findings further indicate may be future on pigmentation and/or analyses additional torenia.

Phytoremediation of contaminated soils using ornamental plants

Environmental Reviews, Год журнала: 2017, Номер 26(1), С. 43 - 54

Опубликована: Сен. 14, 2017

Phytoremediation has attracted increasing attention and is a promising technology for addressing soil contamination problems. Unlike other kinds of remediation plants, ornamental plants grown decorative purposes in gardens landscape design projects have been an important source recent years. In addition to beautifying the environment, some can not only grow well but also accumulate or degrade contaminants when growing contaminated with heavy metals organic pollutants. Especially urban areas, it comparatively rare commendable value are applied. this review, we summarized current research on phytoremediation soils using evaluated capacity heavy-metal pollutant-contaminated soils, highlighted specific strong accumulation ability tolerance The findings related main mechanisms were explained. Enhancement measures aimed at promoting bioavailability reviewed article. It hoped that study will draw new path technology.

New insight into the molecular mechanism of colour differentiation among floral segments in orchids

Communications Biology, Год журнала: 2020, Номер 3(1)

Опубликована: Фев. 28, 2020

An unbalanced pigment distribution among the sepal and petal segments results in various colour patterns of orchid flowers. Here, we explored this type mechanism pattern formation flowers Cattleya hybrid 'KOVA'. Our study showed that accumulation displayed obvious spatiotemporal specificity was likely regulated by three R2R3-MYB transcription factors. Before flowering, RcPAP1 specifically expressed epichile to activate anthocyanin biosynthesis pathway, which caused substantial cyanin resulted a purple-red colour. After expression RcPAP2 low level perianths pale pink colour, whereas RcPCP1 only hypochile, where it promoted α-carotene lutein yellow Additionally, propose different combinations AP3- AGL6-like genes might participate KOVA flower formation.

International Journal of Molecular Sciences, Год журнала: 2018, Номер 19(2), С. 515 - 515

Опубликована: Фев. 8, 2018

Small RNAs (sRNA) are a significant group of gene expression regulators for multiple biological processes in eukaryotes. In plants, many sRNA silencing pathways produce extensive array sRNAs with specialized roles. The evidence on record advocates the functions during plant microbe interactions. Host reckoned as mandatory elements defense. involved defense via different include both short interfering RNA (siRNA) and microRNA (miRNA) that actively regulate immunity response to pathogenic attack tackling pathogen-associated molecular patterns (PAMPs) other effectors. pathogen attack, plants protect themselves help sRNA-dependent immune systems. That sRNA-mediated responses play role infections is an established fact. However, regulations several still need research. this review, we discussed topical advancements findings relevant mediated by sRNAs. We attempted point out diverse key defenders It hoped would be exploited mainstream player achieve food security diseases.
