Abstract Phenylpropanoid metabolism is one of the most important metabolisms in plants, yielding more than 8,000 metabolites contributing to plant development and plant–environment interplay. materialized during evolution early freshwater algae that were initiating terrestrialization land plants have evolved multiple branches this pathway, which give rise including lignin, flavonoids, lignans, phenylpropanoid esters, hydroxycinnamic acid amides, sporopollenin. Recent studies revealed many factors participate regulation metabolism, modulate homeostasis when undergo successive developmental processes are subjected stressful environments. In review, we summarize recent progress on elucidating contribution coordination interaction, metabolic flux redirection among diverse routes. addition, our review focuses at transcriptional, post‐transcriptional, post‐translational, epigenetic levels, response phytohormones biotic abiotic stresses.

Опубликована: Янв. 4, 2021

Stilbenes are a small family of polyphenolic secondary metabolites that can be found in several distantly related plant species. These compounds act as phytoalexins, playing crucial role defense against phytopathogens, well being involved the adaptation plants to abiotic environmental factors. Among stilbenes, trans-resveratrol is certainly most popular and extensively studied for its health properties. In recent years, an increasing number stilbene were subjected investigations concerning their bioactivity. This review presents updated knowledge biosynthetic pathway, also focusing on factors eliciting stilbenes biosynthesis. The effects ultraviolet radiation, visible light, ultrasonication, mechanical stress, salt drought, temperature, ozone, biotic stress reviewed context enhancing biosynthesis, both planta cell organ cultures. may shed some light biological roles represents useful tool increase accumulation these valuable compounds.

The long noncoding RNA MdLNC499 bridges MdWRKY1 and MdERF109 function to regulate early-stage light-induced anthocyanin accumulation in apple fruit

The Plant Cell, Год журнала: 2021, Номер 33(10), С. 3309 - 3330

Anthocyanin pigments contribute to plant coloration and are valuable sources of antioxidants in the human diet as components fruits vegetables. Their production is known be induced by light apple fruit (Malus domestica); however, underlying molecular mechanism responsible for early-stage light-induced anthocyanin biosynthesis remains unclear. Here, we identified an ethylene response factor (ERF) protein, ERF109, involved found that it promotes directly binding anthocyanin-related gene promoters. Promoter::β-glucuronidase reporter analysis Hi-C sequencing showed a long noncoding RNA, MdLNC499, located nearby MdERF109, induces expression MdERF109. A W-box cis-element MdLNC499 promoter was regulated transcription factor, MdWRKY1. Transient stable transformation calli allowed us reconstruct MdWRKY1-MdLNC499-MdERF109 transcriptional cascade which MdWRKY1 activated increase turn The MdERF109 protein genes accumulation anthocyanins early stages coloration. Our results provide platform better understanding various regulatory mechanisms

The MdMYB16/MdMYB1‐miR7125‐MdCCR module regulates the homeostasis between anthocyanin and lignin biosynthesis during light induction in apple

New Phytologist, Год журнала: 2021, Номер 231(3), С. 1105 - 1122

Summary Light induces anthocyanin accumulation and hence decides the coloration of apple fruit. It also plays a key role in regulating biosynthesis other secondary metabolites. However, crosstalk between lignin metabolism during light induction, which affects edible quality visual fruit, respectively, have rarely been characterized. In this study, we identified functionally elucidated roles miR7125 its target, cinnamoyl‐coenzyme A reductase gene ( CCR ), homeostasis induction. Overexpressing or inhibiting transiently fruit promoted but reduced production under light‐induced conditions. Consistently, opposite results were observed background repressed overexpressed CCR. We found that repressor MdMYB16 activator MdMYB1 bound to promoter. Transient repression upregulated expression significantly, accompanied by decreased levels MdCCR transcript, resulting reduction an increase accumulation. transient overexpression produced effects ‐RNAi. The reveal novel mechanism MdMYB16/MdMYB1‐miR7125‐MdCCR module collaboratively regulates induction apple.

Long noncoding RNA lncRNA354 functions as a competing endogenous RNA of miR160b to regulate ARF genes in response to salt stress in upland cotton

Plant Cell & Environment, Год журнала: 2021, Номер 44(10), С. 3302 - 3321

Опубликована: Июнь 24, 2021

Long non-coding RNAs (lncRNAs) play important roles in response to biotic and abiotic stress through acting as competing endogenous (ceRNAs) decoy mature miRNAs. However, whether this mechanism is involved cotton salt remains unknown. We report the characterization of an lncRNA, lncRNA354, whose expression was reduced salt-treated localized at nucleus cytoplasm. Using target mimic (eTM) analysis, we predicted that lncRNA354 had a potential binding site for miR160b. Transient tobacco demonstrated miR160b eTM attenuated suppression its genes, including auxin factors (ARFs). Silencing or overexpressing affected ARFs. targets GhARF17/18 resulted taller plants enhanced resistant stress. Overexpression Arabidopsis led dwarf plants, decreased root dry weight tolerance. Our results show lncRNA354-miR160b effect on may modulate signalling thus affect growth. These also shed new light lncRNA-associated responses

A long noncoding RNA functions in high-light-induced anthocyanin accumulation in apple by activating ethylene synthesis

PLANT PHYSIOLOGY, Год журнала: 2022, Номер 189(1), С. 66 - 83

Опубликована: Фев. 4, 2022

Anthocyanin production in apple (Malus domestica) fruit and their consequent coloration can be induced by high-light treatment. The hormone ethylene is also essential for this coloration, but the regulatory relationships that link light with anthocyanin-associated are not well defined. In study, we observed treatment of increased anthocyanin accumulation more than moderate-light did was main contributor activation biosynthesis. A transcriptome study light-treated suggested a long noncoding RNA (lncRNA), MdLNC610, corresponding gene which physically located downstream from 1-aminocyclopropane-1-carboxylate oxygenase (ACO) biosynthesis MdACO1, likely affects under Expression promoter β-glucuronidase reporter analyses further showed MdLNC610 upregulates expression MdACO1 so participates high-light-induced Overexpression calli indicated major increase activates expression, thereby causing an levels. These results suggest regulation functioning as positive regulator to promote Our provides insights into relationship between mRNA lncRNA networks biosynthetic pathway fruit.

Low temperature can affect the growth and development of plants through changes in DNA demethylation patterns. Another known effect low is accumulation anthocyanin pigments. However, it not whether two phenomena are linked, specifically, participates response to low-temperature stress. The ROS1 gene involved plant influences methylation levels In this study, using RNA sequencing, we detected that transcription MdROS1 correlate with content, as well those biosynthesis-related genes apple (Malus domestica), at temperatures. Genomic bisulfite sequencing showed promoters related MdCHS, MdCHI, MdF3'H, MdANS, MdUFGT, MdMYB10 decreased leaves after treatment. Similar expression results were also found fruit. Transiently silencing fruit cultivars inhibited anthocyanins led biosynthetic genes, opposite MdROS1-overexpressing A promoter binding assay conserved RRD-DME domains directly bind MdF3'H MdUFGT. Taken together, these suggest affects pathway by decreasing level anthocyanin-related promoters, thereby increasing their accumulation.
