The Arabidopsis thaliana somatic embryogenesis receptor kinases (SERKs) consist of five members, SERK1 to SERK5, the leucine-rich repeat receptor-like kinase subfamily II (LRR-RLK II). SERK3 was named BRI1-Associated Receptor Kinase 1 (BAK1) due its direct interaction with brassinosteroid (BR) BRI1 in vivo, while SERK4 has also been designated as BAK1-Like (BKK1) for functionally redundant role BAK1. Here we provide genetic and biochemical evidence demonstrate that SERKs are absolutely...
Atriplex canescens (fourwing saltbush) is a C4 perennial fodder shrub with excellent resistance to salinity. However, the mechanisms underlying salt tolerance in are poorly understood. In this study, 5-week-old A. seedlings were treated various concentrations of external NaCl (0-400 mM). The results showed that growth was significantly stimulated by moderate salinity (100 mM NaCl) and unaffected high (200 or 400 NaCl). Furthermore, higher photosynthetic capacity under treatments (except for...
Light quality surrounding a plant is largely determined by the density of its neighboring vegetation. Plants are able to sense shade light signals and initiate series adaptation responses, which known as avoidance syndrome (SAS). PHYTOCHROME INTERACTING FACTORS (PIFs) key factors in SAS network regulating biosynthesis multiple phytohormones expression cell expansion genes. Although protein levels PIFs were found be acumulated shade, transcriptional regulation response such an environmental...
Brassinosteroids (BRs), a group of plant steroidal hormones, play critical roles in many aspects growth and development. Previous studies showed that BRI1-mediated BR signaling regulates cell division differentiation during Arabidopsis root development via interplaying with auxin other phytohormones. somatic embryogenesis receptor-like kinases (SERKs), as co-receptors BRI1, were found to fundamental role an early activation step pathway. Here we report novel function SERKs regulating Genetic...
SMALL AUXIN-UP RNAs (SAURs) comprise the largest family of early auxin response genes. Some SAURs have been reported to play important roles in plant growth and development, but their functional relationships with signaling remain unestablished. Here, we report Arabidopsis (Arabidopsis thaliana) SAUR15 acts downstream factors ARF6,8 ARF7,19 regulate signaling-mediated lateral root (LR) adventitious (AR) formation. The loss-of-function mutant saur15-1 exhibits fewer LRs ARs. By contrast,...
Abstract Brassinosteroids (BRs) are an important group of plant steroid hormones that regulate growth and development. Several members the SMALL AUXIN UP RNA (SAUR) family have roles in BR-regulated hypocotyl elongation root growth. However, mechanisms unclear. Here, we show Arabidopsis (Arabidopsis thaliana) SAUR15 interacts with cell surface receptor-like kinase BRASSINOSTEROID-INSENSITIVE 1 (BRI1) BR-treated plants, resulting enhanced BRI1 phosphorylation status recruitment co-receptor...
Abstract Revealing the genetic basis for stress-resistant traits in extremophile plants will yield important information crop improvement. Zygophyllum xanthoxylum, an extant species of ancient Mediterranean, is a succulent xerophyte that can maintain favorable water status under desert habitats; however, this adaptive trait poorly understood. Furthermore, phylogenetic position Zygophyllales, to which Z. xanthoxylum belongs, remains controversial. In study, we sequenced and assembled...
Brassinosteroids are phytohormones involved in plant development and physiological processes. Insensitive 1 (BRI1) is required for BR perception initiation of subsequent signal transduction Arabidopsis. In this study, the orthologue BRI1 model legume species Medicago truncatula, MtBRI1, was identified characterised. Three allelic Tnt1 insertion mutants, mtbri1-1, mtbri1-2, mtbri1-3, were obtained from M. truncatula population. mtbri1 mutants displayed characteristic bri1 mutant phenotypes:...
In plants, LRR-RLKs play central roles in regulating perception of extracellular signals and initiation cellular responses under various environmental challenges. Arabidopsis SERK genes, including SERK1 to SERK5, constitute a LRR-RLK sub-family. SERK1, SERK2, SERK3/BAK1 SERK4/BKK1 have been well characterized function as crucial regulators multiple physiological processes such brassinosteroid signaling, cell death control, pathogenesis, pollen development. Despite extremely high sequence...
Zygophyllum xanthoxylum is a succulent xerophyte with remarkable tolerance to diverse abiotic stresses. Previous studies have revealed important physiological mechanisms and identified functional genes associated stress tolerance. However, knowledge of the regulatory conferring in this species poorly understood.Here, we present comprehensive analysis based on transcriptome Z. roots exposed osmotic salt treatments. Significant changes were observed transcripts related known obscure...
Abstract Background As a xerophytic shrub, forming developed root system dominated with lateral roots is one of the effective strategies for Zygophyllum xanthoxylum to adapt desert habitat. However, molecular mechanism formation in Z. still unclear. Auxin response factors (ARFs) are master family transcription (TFs) auxin-mediated biological processes including growth and development. Results Here, determine relationship between ARFs , total 30 potential ZxARF genes were first identified,...
Numerous auxiliary nuclear factors have been identified to be involved in the dynamics of photosystem II (PSII) complex. In this study, we characterized high chlorophyll fluorescence243 (hcf243) mutant Arabidopsis (Arabidopsis thaliana), which shows higher fluorescence and is severely deficient accumulation PSII supercomplexes compared with wild type. The amount core subunits was greatly decreased, while outer antenna other were hardly affected hcf243. vivo protein-labeling experiments...
Drought and salinity can result in cell dehydration water unbalance plants, which seriously diminish plant growth development. Cellular homeostasis maintained by aquaporin is one of the important strategies for plants to cope with these two stresses. In this study, a stress-induced aquaporin, ZxPIP1;3, belonging PIP1 subgroup, was identified from succulent xerophyte Zygophyllum xanthoxylum. The subcellular localization showed that ZxPIP1;3-GFP located plasma membrane. overexpression ZxPIP1;3...
Most studies on salt tolerance in plants have been conducted using glycophytes like Arabidopsis thaliana (L.) Heynh., with limited resistance to salinity. The xerohalophyte Zygophyllum xanthoxylum (Bunge) Engl. is a salt-accumulating desert plant that efficiently transports Na+ into vacuoles manage and exhibits increased growth under salinity conditions, suggesting unique transcriptional response compared glycophytes. We used transcriptome profiling by RNA-seq compare gene expression roots...
Brassinosteroids (BRs) are essential phytohormones mainly perceived by a single-pass transmembrane receptor-like protein kinase (RLK), BRASSINOSTEROID INSENSITIVE 1 (BRI1). bri1-5 and bri1-9, two distinct mutants with point mutations in the extracellular domain, show weak defective phenotypes. Previous studies indicated that bri1-9 mutated proteins can be recognized eliminated via an endoplasmic reticulum quality control (ERQC) mechanism. Most of these proteins, therefore, cannot reach their...
