Abstract:
... The beneficial root-colonizing fungus Piriformospora indica stimulates root development of Chinese cabbage (Brassica campestris subsp. Chinensis) and this is accompanied by the up-regulation of a τ-class glutathione (GSH)-S-transferase gene (BcGSTU) (Lee et al. 2011) in the roots. BcGSTU expression is further promoted by osmotic (salt and PEG) and heat stress. Ectopic expression of BcGSTU in Arabi ...

... Auxin, which has been implicated in multiple biochemical and physiological processes, elicits three classes of genes (Aux/IAAs, SAURs and GH3s) that have been characterized by their early or primary responses to the hormone. A new GH3-like gene was identified from a suppressive subtraction hybridization (SSH) library of pungent pepper (Capsicum chinense L.) cDNAs. This gene, CcGH3, possessed sever ...

Abstract:
... Homeobox (HB) proteins are important transcription factors that regulate the developmental decisions of eukaryotes. WUSCHEL-related homeobox (WOX) transcription factors, known as a plant-specific HB family, play a key role in plant developmental processes. Our previous work has indicated that rhizoids are induced by auxin in rose (Rosa spp.), which acts as critical part of an efficient plant regen ...

Abstract:
... Induction of a pluripotent cell mass termed callus is the first step in an in vitro plant regeneration system, which is required for subsequent regeneration of new organs or whole plants. However, the early molecular mechanism underlying callus initiation is largely elusive. Here, we analyzed the dynamic transcriptome profiling of callus initiation in Arabidopsis aerial and root explants and ident ...

Abstract:
... The plant hormone auxin plays critical roles in plant growth and development. Auxin response factors (ARFs) are a class of transcription factors which regulate auxin-mediated gene expression. While the functions of ARFs in sporophytic development have been well characterized, their functions specific to gametophytic development have not been studied extensively. In this study, Arabidopsis ARF gene ...

Abstract:
... Homeostasis of brassinosteroids (BRs) maintained by the balance between their biosynthesis and inactivation is important to coordinate the diverse physiological and developmental responses of plants. Although BR signaling regulates the endogenous levels of BRs via negative feedback regulation, it remains largely unknown how the biosynthesis and inactivation of BR are triggered. BAS1 encodes CYP734 ...

Abstract:
... Plants sense the presence of competing neighboring vegetation as a change in light quality: i.e. they sense the reduced ratio of red light to far-red light. The responses to shade are generally referred to as the shade avoidance syndrome (SAS), and involve various developmental changes intended to outgrow or outcompete the neighboring plants. Here, we analyze the function of ATHB4, a gene encoding ...

Abstract:

Here, we show that AtHB23 (a homeodomain‐leucine zipper I TF) participates in this intricate network. Our study of the expression pattern of AtHB23 revealed that it is transcriptionally activated in the early stages of secondary LR primordium (LRP). We found that AtHB23 ...

Abstract:
... The phytohormone auxin is involved in almost all developmental processes in land plants. Most, if not all, of these processes are mediated by changes in gene expression. Auxin acts on gene expression through a short nuclear pathway that converges upon the activation of a family of DNA-binding transcription factors. These AUXIN RESPONSE FACTORS (ARFs) are thus the effector of auxin response and tra ...
