To assess the interrelation between change of metabolites and fruit color, we performed a combined metabolome transcriptome analysis flesh in two different Actinidia arguta cultivars: "HB" ("Hongbaoshixing") "YF" ("Yongfengyihao") at developmental stages: 70d (days after full bloom) 100d bloom). Metabolite transcript profiling was obtained by ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometer high-throughput RNA sequencing, respectively. The...
Abstract Proanthocyanidins (PAs) are important metabolites that enhance freezing tolerance of plants. Actinidia arguta , especially freezing‐tolerant germplasms, accumulate abundant PAs in dormant shoots and thereby tolerance, but the underlying mechanism is unknown. In this study, we used two A. with contrasting cold‐resistant phenotypes, KL RB, to explore mechanisms response cold tolerance. We determined a leucoanthocyanidin reductase gene ( AaLAR1 ) was more highly expressed than...
Abstract Beta-amylase (BAM) plays an important role in plant resistance to cold stress. However, the specific of BAM gene freezing tolerance is poorly understood. In this study, we demonstrated that a cold-responsive module was involved kiwifruit. module, expression AaBAM3.1 , which encodes functional protein, induced by -overexpressing kiwifruit lines showed increased tolerance, and heterologous overexpression Arabidopsis thaliana resulted similar phenotype. The results promoter GUS...
The Actinidia (kiwifruit) is an emerging fruit plant that severely affected by salt stress in northern China. Plants have evolved several signaling network mechanisms to cope with the detrimental effects of stress. To date, no reported work available on metabolic and molecular involved kiwifruit tolerance. Therefore, present study aims decipher intricate adaptive responses two contrasting tolerance species valvata [ZMH (an important genotype), hereafter referred as R] deliciosa ['Hayward'...
As important regulators, miRNAs could play pivotal roles in regulation of fruit coloring. Actinidia arguta is a newly emerged tree with extensively application prospects. However, involved A. coloring are unknown. In this study, were investigated at three developmental stages by small RNAs high-throughput sequencing. A total 482 conserved corresponding to 526 pre-miRNAs and 581 novel 619 grouped into 46 miRNA families. Target gene prediction analysis revealed that miR858, strongly candidate...
Cold stress poses a serious treat to cultivated kiwifruit since this plant generally has weak ability tolerate freezing tolerance temperatures. Surprisingly, however, the underlying mechanism of kiwifruit’s remains largely unexplored and unknown, especially regarding key pathways involved in conferring trait. Here, we studied metabolome transcriptome profiles freezing-tolerant genotype KL ( Actinidia arguta ) freezing-sensitive RB A. ), identify main important metabolites related their...
Abstract Background Kiwifruit ( Actinidia Lindl.) is considered an important fruit species worldwide. Due to its temperate origin, this highly vulnerable freezing injury while under low-temperature stress. To obtain further knowledge of the mechanism underlying tolerance, we carried out a hybrid transcriptome analysis two A. arguta Actinidi ) genotypes, KL and RB, whose tolerance high low, respectively. Both genotypes were subjected − 25 °C for 0 h, 1 4 h. Results SMRT (single-molecule...
Actinidia valvata possesses waterlogging tolerance; however, the mechanisms underlying this trait are poorly characterized. Here, we performed a transcriptome analysis by combining single-molecule real-time (SMRT) sequencing and Illumina RNA investigated physiological responses of roots KR5 (A. valvata, tolerant genotype) after 0, 12, 24 72 h stress. responded to stress mainly via carbohydrate free amino acids metabolism reactive oxygen species (ROS) scavenging pathways....
Kiwifruit bacterial canker is a devastating disease threatening kiwifruit production. To clarify the defense mechanism in response to Pseudomonas syringae pv. actinidiae (Psa), we observed phenotypic changes resistant Huate (HT) and susceptible Hongyang (HY) varieties at 0, 12, 24, 48, 96, 144 hour after inoculation (hai) with Psa. Brown lesions appeared areas 12 hai HY shoots, lesion length gradually increased from 24 h. In contrast, no were found HT shoots any time points. Furthermore,...
Ion transport is crucial for salt tolerance in plants. Under stress, the high-affinity K+ transporter (HKT) family mainly responsible long-distance of ions which help to reduce deleterious effects high concentrations accumulated within Kiwifruit well known its susceptibility stress. Therefore, a current study was designed decipher molecular regulatory role kiwifruit HKT members face The transcriptome data from Actinidia valvata revealed that stress significantly induced expression AvHKT1. A...
Waterlogging stress is one of the greatest environmental threats to kiwifruit growth and development. ERF-VII proteins have been demonstrated play pivotal roles in regulating plant tolerance waterlogging. Nevertheless, genome-wide role waterlogging remains unclear. Here, we report function regulatory network an transcription factor located nucleus, AvERF73, tolerance. Overexpression AvERF73 Arabidopsis thaliana A. chinensis cv. Hongyang enhanced transgenic plants. Furthermore, performed...
Red Actinidia arguta has recently become highly popular because of its red appearance resulting from anthocyanin accumulation, and gradually an important breeding direction. However, regulators involved in biosynthesis have not been fully characterized A. arguta. Here, we demonstrated that a key R2R3-MYB transcription factor, AaMYB61-like, plays crucial role biosynthesis. The RT-qPCR results revealed transient overexpression AaMYB61-like fruit at 90–100 DAFB significantly promoted...
The C-repeat binding factors (CBFs) gene is essential for plants’ cold response, which could not only be induced by the inducer of CBF expression (ICE) genes but also activated cold-regulated (COR) gene, thereby participating in ICE-CBF-COR response pathway. However, this family and its functions Actinidia arguta remain unclear. In study, whole-genome identification functional analysis members A. were performed. Eighteen genes, located on four chromosomes had five tandem repeats, identified....
Kiwifruit is a dioecious woody liana fruit tree, and the non-fruitfulness of male plants leads to great deal blindness in selection crossbreeding. In this study, we induced development plant ovary by externally applying growth regulators (PGRs) performed histological observation, phytohormone content determination transcriptome analysis on abortive kiwifruit (Con), female (Fem) PGR-induced developing (PT). Histological showed that Con was devoid ovules carpels were atrophied, Fem had PT...
Abstract Actinidia arguta is a newly emerged, commercially cultivated species. A. has beautiful appearance and rich in anthocyanin, thus highly welcomed by consumers. However, the mechanism of anthocyanin regulation remains unclear. In this study, we assembled nearly complete genome first red cultivar, ‘Tianyuanhong’, with an N50 21 Mb. Comparative analysis revealed role expansion/contraction gene families species-specific trait formation . Through verification transient overexpression...
In this study, four genotypes (Acva-1, Acva-2, Acva-3 and ZM-2) of Actinidia germplasm resources were grown in different NaCI concentrations (0, 0.4, 0.8 1.2 g L–1). The growth, physiological biochemical indicators measured, a graded scale was developed as the salt damage index (SDI) according to symptoms leaves. results showed SDI increased gradually, average number length new shoot decreased significantly. Three antioxidant enzymes (superoxide dismutase, peroxidase catalase) two osmotic...
