Abiotic stresses, such as drought, high temperature, and salinity, affect plant growth productivity. Furthermore, global climate change may increase the frequency severity of abiotic suggesting that development varieties with improved stress tolerance is critical for future sustainable crop production. Improving requires a detailed understanding hormone signaling transcriptional pathways involved in responses. Abscisic acid (ABA) jasmonic (JA) are key stress-response hormones plants, some...
Root hairs are long tubular outgrowths that form on the surface of specialized epidermal cells. They required for nutrient and water uptake interact with soil microflora. Here we show Oryza sativa cellulose synthase-like D1 (OsCSLD1) gene is root hair development, as rice (Oryza sativa) mutants lack OsCSLD1 function develop abnormal hairs. In these mutants, while development initiated normally, elongate less than wild-type they have kinks swellings along their length. Because csld1 same...
Indeterminate 1 (Id1), a classical flowering gene first reported in 1946, is one of the earliest genes whose expression leaf tissues affects floral transition shoot meristem. How Id1 integrated into process largely unknown. In this study, we examined genetic action rice (Oryza sativa) ortholog OsId1. rice, OsId1 preferentially expressed young leaves, but overall pattern broader than that maize (Zea mays). able to activate transcription yeast. RNAi mutants show delay under both short-day (SD)...
We report the expression cloning of pMev, a cDNA that facilitates cellular uptake mevalonate. pMev was isolated from met-18b-2 clone Chinese hamster ovary (CHO) cells, which were selected for growth in low concentrations mevalonate when synthesis is blocked by compactin (Faust, J. R., and Krieger, M. (1987) Biol. Chem. 262, 1996-2004). encodes 494-residue protein, Mev, predicted to have 12 membrane-spanning regions, consistent with membrane transporter. Surprisingly, levels Mev mRNA protein...
Abstract Temporal and spatial variation in the levels of sensitivity to hormones are essential for development higher organisms. Traditionally, end-product feedback regulation has been considered as key mechanism achievement cellular homeostasis. Brassinosteroids (BRs) plant steroid that perceived by cell surface receptor kinase Brassinosteroid Insensitive1. Binding these activates BR signaling eventually suppresses synthesis. This report shows RAVL1 regulates expression receptor....
Mutants without root hairs show reduced inorganic orthophosphate (Pi) uptake and compromised growth on soils when Pi availability is restricted. What less clear whether that are longer than wild-type provide an additional benefit to phosphorus (P) nutrition. This was tested using transgenic Brachypodium lines with hairs. The were transformed the endogenous BdRSL2 BdRSL3 genes either a constitutive promoter or hair-specific promoter. Plants grown for 32 d in soil amended various...
The burgeoning interest in natural components personal care products has led to significant research and development of ingredients such as plant extracts, antioxidants, peptides, probiotics. These have been recognized for their potential enhance skin health through various mechanisms, addressing consumer demand that are both effective benign. Plant known rich composition bioactive compounds, offer a myriad benefits including antioxidant, anti-inflammatory, antimicrobial properties, making...
Summary Rapid, large‐scale generation of a Ds transposant population was achieved using regeneration procedure involving tissue culture seed‐derived calli carrying Ac and inactive elements. In the F 2 progeny from genetic crosses between same starter lines, most produced an independent germinal transposition frequency 10–20%. Also, many elements underwent immobilization even though expressed. By comparison, in callus‐derived regenerated population, over 70% plants carried insertions,...
Although serum bile acid concentrations are approximately 10 µM in healthy subjects, the crosstalk between biliary system and vascular repair has never been investigated. In this study, tauroursodeoxycholic (TUDCA) induced dissociation of CD34(+) hematopoietic stem cells (HSCs) from stromal by reducing adhesion molecule expression. TUDCA increased /Sca1(+) progenitors mice peripheral blood (PB), , CD31(+) c-kit(+) human PB. addition, differentiation HSCs into EPC lineage via Akt activation....
Genes encoding ROOT HAIR DEFECTIVE SIX-LIKE (RSL) class I basic helix loop proteins are expressed in future root hair cells of the Arabidopsis thaliana meristem where they positively regulate cell development. Here we show that there three RSL protein coding genes Brachypodium distachyon genome, BdRSL1, BdRSL2 and BdRSL3, each is developing after asymmetric division forms hairless epidermal cells. Expression BdRSL sufficient for development: ectopic overexpression any induces development...
• The root epidermis of most angiosperms comprises hair (H) cells and nonhair (N) cells. H are shorter than N in grasses (Poaceae). aim this study was to determine the developmental basis for differences cell size Brachypodium distachyon Oryza sativa. We show that cytokinesis last division each epidermal file is asymmetric B. distachyon. smaller daughter becomes an larger forms cell. By contrast, does not occur during development O. sativa arise because there more expansion after initiation....
Root hairs are filamentous protuberances from superficial cells of plant roots that critical for nutrient uptake. Genes encoding ROOT HAIR DEFECTIVE-SIX LIKE (RSL) class I basic helix-loop-helix proteins expressed in future root hair (trichoblasts) the Arabidopsis thaliana where they positively regulate cell development. We characterized function genes Oryza sativa show there three RSL O. and each is developing cells. Reduction results development shorter than wild-type. Ectopic...
Tomato fruit color is primarily influenced by the accumulation of pigments such as carotenoids and anthocyanins, which are regulated a complex network genes environmental factors. The presence in particular, contributes to purple phenotype tomatoes, has been associated with improved nutritional quality disease resistance. Previous studies have identified key regulatory genes, including SlMYBATV SlANT1, that control anthocyanin biosynthesis tomatoes. A total 48 tomato accessions were...
Anthropogenic methane emissions are a leading cause of the increase in global average temperatures, often referred to as warming. Flooded soils play significant role production, where anaerobic conditions promote production by methanogenic microorganisms. Rice fields contribute considerable portion agricultural emissions, rice plants provide both factors that enhance and limit production. harbor methane- producing methane-oxidizing Exudates from roots source for while oxygen delivered root...
The promotive effects of brassinosteroids (BRs) on plant growth and development have been widely investigated; however, it is not known whether BRs directly affect nutrient uptake. Here, we explored the possibility a direct relationship between ammonium uptake via AMT1-type genes in rice (Oryza sativa). BR treatment increased expression AMT1;1 AMT1;2, whereas mutant d61-1, which defective BR-receptor gene BRI1, BR-dependent these was suppressed. We then employed Related to ABI3/VP1-Like 1...
Genomic DNAs extracted from 1,288 Haemaphysalis longicornis ticks collected grass vegetation and various animals nine provinces of Korea were subjected to screening by genus-specific (Ehrlichia spp. or Anaplasma spp.) real-time TaqMan PCR speciesspecific (E. chaffeensis) nested-PCR based on amplification 16S rRNA gene fragments. In all, 611 (47.4%) tested positive for 116 bp fragment Ehrlichia Subsequently, 396 E. chaffeensis-specific was amplified 4.2% (26/611) tick samples. The comparison...
INDETERMINATE DOMAIN 10 (IDD10) is a key transcription factor gene that activates the expression of large number NH4+-responsive genes including AMMONIUM TRANSPORTER 1;2 (AMT1;2). Primary root growth rice (Oryza sativa) idd10 mutants hypersensitive to NH4+. The involvement CALCINEURIN B-LIKE INTERACTING PROTEIN KINASE (CIPK) in action IDD10 on NH4+-mediated was investigated.Quantitative reverse transcription-PCR used analyse NH4+- and IDD10-dependent CIPK genes. IDD10-regulated target were...
