A pathogenesis-related gene, ScPR10 , was isolated from sugarcane and its bio-function was characterized, demonstrating that ScPR10 was involved in plant defense responses to Sporisorium scitamineum , SrMV, SA, and MeJA stresses. Plant fungal and viral diseases are the major concerns in sugarcane industry. Many anti-fungal and antivirus components, including pathogenesis-related (PR) proteins, have been identified. The pathogenesis-related protein 10 (PR10) is the dominant group in PR families, involved in the plant defense mechanism...

Jiaping Yan, Dun Mao, Xiaomeng Liu, Lanlan Wang, Feng Xu, Guiyuan Wang, Weiwei Zhang, Yongling Liao
This is the first report to clone and functionally characterize a flowering time gene GbCO in perennial gymnosperm Ginkgo biloba. GbCO complements the co mutant of Arabidopsis, restoring normal early flowering. CONSTANS (CO) is a central regulator of photoperiod pathway, which channels inputs from light, day length, and circadian clock to promote the floral transition. In order to understand the role of CO in gymnosperm Ginkgo biloba, which has a long juvenile phase (15-20 years), a CO homolog (GbCO) was isolated and characterized from G...

An anther-specific GRP gene, regulated by PhMYC2 , causes a significant reduction of male fertility when overexpressed in petunia, and its promoter is efficient in genetic engineering of male-sterile lines. Glycine-rich proteins (GRPs) play important roles in plant anther development; however, the underlying mechanisms and related regulatory networks are poorly understood. In this study, a novel glycine-rich family gene designated as PhGRP was isolated from Petunia hybrida 'Fantasy Red'. The qRT-PCR analysis showed that it expressed specifically in anthers, and its expression peaked earlier than those well-known tapetum-specific genes, such as TA29, and several genes with the classic cis-regulatory element 'anther-box' in petunia during its anther development...

Using CRISPR/Cas9, we successfully deleted large fragments of the yield-related gene DENSE AND ERECT PANICLE1 in Indica rice at relatively high frequency and generated gain-of-function dep1 mutants. CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 is a rapidly developing technology used to produce gene-specific modifications in both mammalian and plant systems. Most CRISPR-induced modifications in plants reported to date have been small insertions or deletions. Few large target gene deletions have thus far been reported, especially for Indica rice...

Insertion of a solo LTR, which possesses strong bidirectional, stem-specific promoter activities, is associated with the evolution of a dwarfing apple spur mutation. Spur mutations in apple scions revolutionized global apple production. Since long terminal repeat (LTR) retrotransposons are tightly related to natural mutations, inter-retrotransposon-amplified polymorphism technique and genome walking were used to find sequences in the apple genome based on these LTRs. In 'Red Delicious' spur mutants, a novel, 2190-bp insertion was identified as a spur-specific, solo LTR (sLTR) located at the 1038th nucleotide of another sLTR, which was 1536 bp in length...

Triticum durum Glutathione S-transferase Z1 is specifically responsive to glyphosate. Its expression influences the receptor-mediated vacuolar sorting mechanisms involved in tolerance mechanisms. A zeta subfamily glutathione S-transferase gene from Triticum durum (cv Cappelli) (TdGSTZ1) was characterized as part of a complex detoxification mechanism. The effect of different abiotic stresses on TdGSTZ1 revealed that the gene is unexpectedly responsive to glyphosate (GLY) herbicide despite it should not be part of tolerance mechanisms...

A novel R2R3 MYB transcription factor PtrMYB57 interacted with bHLH131 and PtrTTG1 to form the MBW complex and negatively regulated the biosynthesis of both anthocyanins and PAs in poplar. R2R3-MYB transcription factors (TFs) are important regulators of secondary metabolite biosynthesis in woody species. A series of R2R3-MYB TFs involved in anthocyanin and proanthocyanidin (PA) biosynthesis have been identified in poplar. In this study, we report the identification and characterization of a subgroup 4 MYB member PtrMYB57, which contains a repressor domain (LxLxL) at the C-terminal end...

Transient 5-azacytidine treatment of leaf explants from potato plants with transcriptionally silenced transgenes allows de novo regeneration of plants with restored transgene expression at the whole plant level. Transgenes introduced into plant genomes frequently become silenced either at the transcriptional or the posttranscriptional level. Transcriptional silencing is usually associated with DNA methylation in the promoter region. Treatments with inhibitors of maintenance DNA methylation were previously shown to allow reactivation of transcriptionally silenced transgenes in single cells or tissues, but not at the whole plant level...

A Salvia miltiorrhiza R2R3-MYB gene, SmMYB9b , has been cloned and characterized. Overexpression of SmMYB9b resulted in a significant improvement of tanshinones, the lipophilic active ingredients in danshen hairy roots. Plant R2R3-MYB transcription factors play important roles in various physiological and biochemical processes. Danshen (Salvia miltiorrhiza bunge) is a valuable medicinal herb with tanshinones and salvianolic acids as the principal bioactive ingredients. A number of putative R2R3-MYB transcription factors have been identified in the plant, but their function remains to be studied...

Overexpression of OsNRT2.3b in rice can increase Pi uptake and accumulation through advanced root system, enhanced OsPT and OsPHR genes expression, and the phloem pH homeostasis. Nitrogen (N) and phosphorus (P) are two essential macronutrients for plants. Overexpression of the rice nitrate transporter, OsNRT2.3b, can improve rice grain yield and nitrogen use efficiency (NUE). Here, OsNRT2.3b overexpression resulted in increased grain yield, straw yield, and grain:straw ratio, accompanied by increased P concentrations in the leaf blade, leaf sheath, culm, and unfilled rice hulls...

The semi-aquatic plant Water-Wisteria is suggested as a new model to study heterophylly due to its many advantages and typical leaf phenotypic plasticity in response to environmental factors and phytohormones. Water-Wisteria, Hygrophila difformis (Acanthaceae), is a fast growing semi-aquatic plant that exhibits a variety of leaf shapes, from simple leaves to highly branched compound leaves, depending on the environment. The phenomenon by which leaves change their morphology in response to environmental conditions is called heterophylly...

A Salicornia europaea L. in vitro cell transformation system was developed and further applied to SeNHX1 function investigation. The exploration of salt-tolerant genes from halophyte has seriously been limited by the lack of self-dependent transformation system. Here, an Agrobacterium tumefaciens-mediated in vitro cell transformation system of euhalophyte Salicornia europaea L. was developed. Calli derived from hypocotyl of S. europaea were co-cultured for 3 days with Agrobacterium at OD600 ranging from 1...

NOR loci of C-subgenome are dominant in wheat × Aegilops interspecific hybrids, which may have evolutionary implications for wheat group genome dynamics and evolution. After interspecific hybridisation, some genes are often expressed from only one of the progenitor species, shaping subsequent allopolyploid genome evolution processes. A well-known example is nucleolar dominance, i.e. the formation of cell nucleoli from chromosomes of only one parental species. We studied nucleolar organizing regions (NORs) in diploid Aegilops markgrafii (syn: Ae...

MaATG8s play important roles in hypersensitive-like cell death and immune response, and autophagy is essential for disease resistance against Foc in banana. Autophagy is responsible for the degradation of damaged cytoplasmic constituents in the lysosomes or vacuoles. Although the effects of autophagy have been extensively revealed in model plants, the possible roles of autophagy-related gene in banana remain unknown. In this study, 32 MaATGs were identified in the draft genome, and the profiles of several MaATGs in response to fungal pathogen Fusarium oxysporum f...

The ectopic expression of AtDFR results in increased accumulation of anthocyanins leading to enhanced salinity and drought stress tolerance in B. napus plants. Flavonoids with antioxidant effects confer many additional benefits to plants. Evidence indicates that flavonoids, including anthocyanins, protect tissues against oxidative stress from various abiotic stressors. We determined whether increases in anthocyanins increased abiotic stress tolerance in Brassica napus, because the values of B. napus L. and its cultivation area are increasing worldwide...
