“…SuSy is believed to function in channeling UDP-glucose from sucrose to various -glucan synthases for cellulose biosynthesis. Its activity was positively correlated with cell wall biosynthesis (Klinge et al 1997) and with cell wall thickening by cellulose deposition in roots in response to stress (Albrecht and Mustroph 2003). In this study, SuSy 1 was identiWed with high expression in Chisholm-T after 3 h and 7 days of Al exposure.…”

To understand the mechanisms of aluminum (Al) tolerance in wheat (Triticum aestivum L.), suppression subtractive hybridization (SSH) libraries were constructed from Al-stressed roots of two near-isogenic lines (NILs). A total of 1,065 putative genes from the SSH libraries was printed in a cDNA array. Relative expression levels of those genes were compared between two NILs at seven time points of Al stress from 15 min to 7 days. Fifty-seven genes were differentially expressed for at least one time point of Al treatment. Among them, 28 genes including genes for aluminum-activated malate transporter-1, ent-kaurenoic acid oxidase-1, beta-glucosidase, lectin, histidine kinase, and phospoenolpyruvate carboxylase showed more abundant transcripts in Chisholm-T and therefore may facilitate Al tolerance. In addition, a set of genes related to senescence and starvation of nitrogen, iron, and sulfur, such as copper chaperone homolog, nitrogen regulatory gene-2, yellow stripe-1, and methylthioribose kinase, was highly expressed in Chisholm-S under Al stress. The results suggest that Al tolerance may be co-regulated by multiple genes with diverse functions, and those genes abundantly expressed in Chisholm-T may play important roles in enhancing Al tolerance. The down-regulated genes in Chisholm-S may repress root growth and restrict uptake of essential nutrient elements, and lead to root senescence.

“…In Arabidopsis, several R1-MYB proteins, such as EPR1 (Kuno et al , 2003), LHY (Schaffer et al , 1998), and CCA1 (Wang and Tobin, 1998), have been isolated and confirmed as circadian oscillators involved in developmental modulation in plants. In maize, R1-MYB affects developing cells in the root or shoot apex, as well as the gibberellin hormone balance (Klinge et al , 1997). The R1-MYB protein was also reported to participate in the stress response process (Cheng et al , 2013).…”

The cDNA encoding the R1-MYB transcription factor, designated as JcR1MYB1, was isolated from Jatropha curcas using rapid amplification of cDNA ends. JcR1MYB1 contains a 951 bp open reading frame that encodes 316 amino acids. The deduced JcR1MYB1 protein was predicted to possess the conserved, 56-amino acid-long DNA-binding domain, which consists of a single helix-turn-helix module and usually occurs in R1-MYBs. JcR1MYB1 is a member of the R1-MYB transcription factor subfamily. A subcellular localization study confirmed the nuclear localization of JcR1MYB1. Expression analysis showed that JcR1MYB1 transcripts accumulated in various examined tissues, with high expression levels in the root and low levels in the stem. JcR1MYB1 transcription was up-regulated by polyethylene glycol, NaCl, and cold treatments, as well as by abscisic acid, jasmonic acid, and ethylene treatment. Analysis of transgenic tobacco plants over-expressing JcR1MYB1 indicates an inportant function for this gene in salt stress.

“…This subfamily is further divided into several subgroups, including CCA1-like, I-box-binding-like, TBP-like, TRF-like, CPC-like and other MYB-related proteins (Yanhui et al, 2006). They act as circadian oscillators in developmental modulation (Wang and Tobin, 1998;Kuno et al, 2003, Schaffer et al, 1998, regulate hormone balance (Klinge et al, 1997) and are involved in stress responses (Cheng et al, 2013). 1R MYB TFs are also reported as potential regulators of phenylpropanoid biosynthesis in many plants (Feller et al, 2011;Yi et al, 2010;Zhang et al, 2009;Zhu et al, 2009;Nemie-Feyissa et al, 2014;Dubos et al, 2008;Matsui et al, 2008).…”

Turmeric (Curcuma longa L.) is gaining immense global importance due to the presence of curcumin that contributes to its immunomodulatory properties. Curcumin, a phenylpropanoid derivative, is the most important secondary metabolite present in turmeric rhizomes and understanding the regulatory mechanism of curcumin biosynthesis is hence important. In plants, activator and repressor type transcription factors (TFs) of the myeloblastosis (MYB) family have been found to regulate the biosynthesis of secondary metabolites. MYB TF genes of the R2R3 class were identified by RNA-Seq based approach from turmeric. The present study involves RNA seq based identification, cloning and characterisation of a novel MYB TF of the 1R class. Gene-specific primers were used to amplify 1R MYB from the rhizome, and it was sequenced to give a full-length gene of 1056 bp. The identified MYB gene was designated as ClMYB1R1 and consisted of a 693 bp open reading frame (ORF) which encodes a 230 amino acid length protein with a molecular mass of 25 kDa and pI 9.51. The protein was predicted to consist of a single helix-turn-helix MYB-like motif and other highly conserved residues. ClMYB1R1 expression varied in different genotypes and tissues. UV-C light was found to upregulate, while NaCl and nutrient stresses down-regulated the expression. The expression showed a positive correlation with a candidate pathway gene ClPKS11 under all of the above experimental conditions, indicating the putative role of ClMYB1R1 in regulating curcumin biosynthesis.
