Understanding the responses of plant growth and secondary metabolites to differential light conditions is very important to optimize cultivation conditions of medicinal woody plants. As a highly valued and multiple function tree species, Cyclocarya paliurus is planted and managed for timber production and medical use. In this study, LED-based light including white light (WL), blue light (BL), red light (RL), and green light (GL) were used to affect leaf biomass production, flavonoid accumulation and related gene expression of one-year C...

The infection of legume plants by rhizobia is tightly regulated to ensure accurate bacterial penetration, infection and development of functionally efficient nitrogen-fixing root nodules. Rhizobial Nod Factors (NF) have key roles in the elicitation of nodulation signalling. Infection of white clover roots also involves the tightly regulated specific breakdown of the non-crystalline apex of cell walls in growing root hairs, which is mediated by Rhizobium leguminosarum bv. trifolii cellulase CelC2. Here, we have analyzed the impact of this endoglucanase on symbiotic signalling in the model legume Medicago truncatula...

The atmospheric pollutant ozone (O3 ) is a strong oxidant that causes extracellular reactive oxygen species (ROS) formation, has significant ecological relevance, and is used here as a non-invasive ROS inducer to study plant signalling. Previous genetic screens identified several mutants exhibiting enhanced O3- sensitivity, but few with enhanced tolerance. We found that loss-of-function mutants in Arabidopsis MLO2, a gene implicated in susceptibility to powdery mildew disease, exhibit enhanced dose-dependent tolerance to O3 and extracellular ROS, but a normal response to intracellular ROS...

The underlying adaptive mechanisms by which insect strains are associated with specific plants are largely unknown. In this study, we investigated the role of herbivore-induced defenses in the host plant association of fall armyworm (Spodoptera frugiperda) strains. We tested the expression of herbivore-induced defense-related genes and the activity of plant-defensive proteins in maize and Bermuda grass upon feeding by fall armyworm strains. The rice strain caterpillars induced greater accumulation of proteinase inhibitors in maize than the corn strain caterpillars...

How mycoheterotrophs have evolved and how they are sustained are an enigma. Structural analyses of the plastid genome and phylogenetic analyses of mycoheterotrophs have been used to identify mycorrhizal fungi. Molecular genetic studies have also revealed the mechanism for plant-fungi interactions. However, the evolution of the small, scale-like vegetative leaves of mycoheterotrophs is unknown. As almost all genes determining leaf size affect the floral organ sizes, it is highly implausible that loss-of-function mutations in leaf size regulators caused the evolution of smaller foliage leaves in mycoheterotrophs...

Bangjun Zhou, Lirong Zeng
Plants have evolved a sophisticated innate immune system to contend with potential infection by various pathogens. Understanding and manipulation of key molecular mechanisms that plants use to defend against various pathogens are critical for developing novel strategies in plant disease control. In plants, resistance to attempted pathogen infection is often associated with hypersensitive response (HR), a form of rapid programmed cell death (PCD) at the site of attempted pathogen invasion. In this chapter, we describe a method for rapid identification of genes that are essential for plant innate immunity...

Heat stress (HS) causes detrimental effects on plant morphology, physiology, and biochemistry that lead to drastic reduction in plant biomass production and economic yield worldwide. To date, little is known about HS-responsive genes involved in thermotolerance mechanism in radish. In this study, a total of 6600 differentially expressed genes (DEGs) from the control and Heat24 cDNA libraries of radish were isolated by high-throughput sequencing. With Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, some genes including MAPK, DREB, ERF, AP2, GST, Hsf, and Hsp were predominantly assigned in signal transductions, metabolic pathways, and biosynthesis and abiotic stress-responsive pathways...

Cotton (Gossypium spp.) is an imperative economic crop of the globe due to its natural textile fiber. Molecular mechanisms of fiber development have been greatly revealed in allotetraploid cotton but remained unexplored in Gossypium herbaceum. G. herbaceum can withstand the rigors of nature like drought and pests but produce coarse lint. This undesirable characteristic strongly needs the knowledge of fiber development at molecular basis. The present study reported the transcriptome sequence of the developing fiber of G...

The histone chaperone FACT is involved in the expression of genes encoding anthocyanin biosynthetic enzymes also upon induction by moderate high-light and therefore contributes to the stress-induced plant pigmentation. The histone chaperone FACT consists of the SSRP1 and SPT16 proteins and associates with transcribing RNAPII (RNAPII) along the transcribed region of genes. FACT can promote transcriptional elongation by destabilising nucleosomes in the path of RNA polymerase II, thereby facilitating efficient transcription of chromatin templates...

Latest outcomes assign functional role to non-coding (nc) RNA molecules in regulatory networks that confer male sterility to plants. Male sterility in plants offers great opportunity for improving crop performance through application of hybrid technology. In this respect, cytoplasmic male sterility (CMS) and sterility induced by photoperiod (PGMS)/temperature (TGMS) have greatly facilitated development of high-yielding hybrids in crops. Participation of non-coding (nc) RNA molecules in plant reproductive development is increasingly becoming evident...

This paper reports the first study on plant CBF transcription factors (TF) in salt and drought stress responses in Chrysanthemum lavandulifolium. A CBF homolog gene, named as ClCBF1, from C. lavandulifolium was isolated using rapid amplification of cDNA ends (RACE). The deduced peptide is comprised of 210 amino acids (AA) containing an AP2 structural domain characteristic of the AP2 gene family. Quantitative real-time PCR revealed that ClCBF1 gene exhibit differential expression patterns across root, leaf and stem tissues, and it was strongly induced under salt and drought treatments of C...

Chilling stress severely affects the growth, development and productivity of crops. Chloroplast, a photosynthesis site, is extremely sensitive to chilling stress. In this study, the functions of a gene encoding a cold-regulated protein (SlCOR413IM1) under chilling stress were investigated using sense and antisense transgenic tomatoes. Under chilling stress, SlCOR413IM1 expression was rapidly induced and the sense lines exhibited better growth state of seedlings and grown tomato plants. Overexpression of SlCOR413IM1 alleviated chilling-induced damage to the chloroplast membrane and structure, whereas suppression of SlCOR413IM1 aggravated the damage to chloroplast...

MicroRNAs are small non-coding regulatory RNA molecules that play an important role in the modulation of gene expression during various environmental stresses. Pseudomonas putida RA, a plant growth promoting rhizobacteria (PGPR) colonizes the root surface of plants improving their growth and development during abiotic stresses modulating the expression of stress-responsive genes; however, the impact of RA on stress responsive-miRNA remains elusive. The present study was an attempt to delineate the role of PGPR in modulating stress responsive-miRNAs in a tolerant desi chickpea genotype exposed to drought and salt stresses...

REVIEW
Nerina Gnesutta, Roberto Mantovani, Fabio Fornara
CONSTANS (CO) is a master regulator of flowering time, although the mechanisms underlying its role as a transcriptional regulator are not well understood. The DNA-binding domain of CO shares homology with that of NUCLEAR FACTOR YA (NF-YA), a subunit of the CCAAT-binding trimer NF-Y. Recent publications indicate that CO and its rice homolog HEADING DATE 1 (Hd1) form heterotrimers with the histone-fold subunits of NF-Y to efficiently bind promoter elements in the florigen genes. Differences in the DNA-binding specificities of NF-Y and NF-CO can be conceptualized based on our knowledge of the 3D structure of the NF-Y/CCAAT complex...

The Xanthomonas genus includes Gram-negative plant-pathogenic bacteria, which infect a broad range of crops and wild plant species, cause symptoms with leaf blights, streaks, spots, stripes, necrosis, wilt, cankers and gummosis on leaves, stems and fruits in a wide variety of plants via injecting their effector proteins into the host cell during infection. Among these virulent effectors, transcription activator-like effectors (TALEs) interact with the γ subunit of host transcription factor IIA (TFIIAγ) to activate the transcription of host disease susceptibility genes...

Aphids are pests of chrysanthemum that employ plant volatiles to select host plants and ingest cell contents to probe host quality before engaging in prolonged feeding and reproduction. Changes in volatile and non-volatile metabolite profiles can disrupt aphid-plant interactions and provide new methods of pest control. Chrysanthemol synthase (CHS) from Tanacetum cinerariifolium, represents the first committed step in the biosynthesis of pyrethrin ester insecticides, but no biological role for the chrysanthemol product alone has yet been documented...

Transcription factors (TFs) and chromatin-modifying factors (CMFs) access chromatin by recognizing specific DNA motifs in their target genes. Chromatin Immunoprecipitation followed by next generation sequencing (ChIP-seq) has been widely used to discover the potential DNA binding motifs for both TFs and CMFs. Yet, an in vivo method for verifying DNA motifs captured by ChIP-seq is lacking in plants. Here, we describe the use of clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated 9 (Cas9) to verify DNA motifs in their native genomic context in Arabidopsis...

Kiwifruit is an important fruit crop; however, technologies for its functional genomic and molecular improvement are limited. The clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) system has been successfully applied to genetic improvement in many crops, but its editing capability is variable depending on the different combinations of the synthetic guide RNA (sgRNA) and Cas9 protein expression devices. Optimizing conditions for its use within a particular species is therefore needed to achieve highly efficient genome editing...

The ability of a plant to produce grain, fruit, or forage depends ultimately on photosynthesis. There have been few attempts, however, to study microRNAs, which are a class of endogenous small RNAs post-transcriptionally programming gene expression, in relation to photosynthetic traits. We focused on miR408, one of the most conserved plant miRNAs, and overexpressed it in parallel in Arabidopsis, tobacco, and rice. The transgenic plants all exhibited increased copper content in the chloroplast, elevated abundance of plastocyanin, and an induction of photosynthetic genes...
