“…As shown in Fig. 1, the conserved amino acids characteristic for ALDHs were all present in ALDH22A1 homologs, including the possible NAD + binding site (F-V-G-S-P-G-V-G), the catalytic site (V-T-L-E-L-G-G-K) and the Cys active site (Perozich et al 1999;Kirch et al 2004). The expression of ZmALDH22A1 is enhanced by stress conditions…”

“…The ZmALDH22A1 is a member of a novel aldehyde dehydrogenase gene family (ALDH22 family) unique in plants (Kirch et al 2004(Kirch et al , 2005) and a highly similar ortholog has been found in sugarcane, rice, wheat and Arabidopsis. In contrast to many other ALDH genes that are stress-inducible, the ZmALDH22A1 mRNA accumulation is characterized by differential expressions in various tissues and apparently enhanced by dehydration, high salinity and exogenous application of ABA.…”

“…To date, 22 ALDH families have been identified in eukaryotes, and 12 of them are present in plants (Sophos et al 2001;Kirch et al 2004). Many ALDHs are highly substratespecific, while others possess a broad range of substrates (Yoshida et al 1998;Perozich et al 1999).…”

“…An ALDH family (ALDH22) that is unique in plants has been identified in Arabidopsis genome (Kirch et al 2004(Kirch et al , 2005, but its function remains largely unknown. Here we characterize a maize (Zea mays) ALDH22 homolog (ZmALDH22A1) in transgenic tobacco plants with regard to stress tolerance.…”

Aldehyde dehydrogenases (ALDHs) play a central role in detoxification processes of aldehydes generated in plants when exposed to the stressed conditions. In order to identify genes required for the stresses responses in the grass crop Zea mays, an ALDH (ZmALDH22A1) gene was isolated and characterized. ZmALDH22A1 belongs to the family ALDH22 that is currently known only in plants. The ZmALDH22A1 encodes a protein of 593 amino acids that shares high identity with the orthologs from Saccharum officinarum (95%), Oryza sativa (89%), Triticum aestivum (87%) and Arabidopsis thaliana (77%), respectively. Real-time PCR analysis indicates that ZmALDH22A1 is expressed differentially in different tissues. Various elevated levels of ZmALDH22A1 expression have been detected when the seedling roots exposed to abiotic stresses including dehydration, high salinity and abscisic acid (ABA). Tomato stable transformation of construct expressing the ZmALDH22A1 signal peptide fused with yellow fluorescent protein (YFP) driven by the CaMV35S-promoter reveals that the fusion protein is targeted to plastid. Transgenic tobacco plants overexpressing ZmALDH22A1 shows elevated stresses tolerance. Stresses tolerance in transgenic plants is accompanied by a reduction of malondialdehyde (MDA) derived from cellular lipid peroxidation.

“…In plants there have been 11 ALDH families identified to date: ALDH2, ALDH3, ALDH5, ALDH6, ALDH7, ALDH10, ALDH11, ALDH12, ALDH18, ALDH19, and ALDH21. The families ALDH11, ALDH19 and ALDH21 are unique to plants and, more recently, ALDH sequences encoding members of a novel family, ALDH22, have been identified in Arabidopsis, maize, and rice genomes (Kirch et al 2004).…”

Molecular cloning and differential expression of an aldehyde dehydrogenase gene in rice leaves in response to infection by blast fungus

Aldehyde dehydrogenase (ALDH) superfamily is a group of enzymes metabolizing endogenous and exogenous aldehydes. Using differential display RT-PCR and cDNA library screening, a full-length aldehyde dehydrogenase cDNA (ALDH7B7) was isolated from rice leaves infected by incompatible race of blast fungus Magnaporthe grisea. The deduced amino acid sequence consists of 509 amino acid residues and shares 74∼81% identity with those of ALDH7Bs from other plants. ALDH7B7 expression was induced by blast fungus infection, ultraviolet, mechanical wound in rice leaves and was not detected in untreated rice organs. This gene has also been found to be inducible after exogenous phytohormones application, such as salicylic acid, methyl ester of jasmonic acid and abscisic acid. The function of ALDH7B7 in the interaction process between blast fungus and rice is discussed.

Since the publication of the complete genome sequence of the model plant Arabidopsis thaliana, the precision annotation of the exact function of each gene has become a major research activity. Metabolomic analysis has much to offer in this endeavour and the small physical size and generation time of Arabidopsis make it a particularly attractive system for large‐scale metabolomic data collection and analysis. In this review, we summarize the known phytochemistry of Arabidopsis, with particular emphasis on recent discoveries that indicate that the complexity of this plant's secondary metabolome is much greater than originally realized. We survey how the different analytical technologies, used in metabolomic analysis, are applied to quantify both primary and secondary metabolites of Arabidopsis. The use of isotope labelling to derive empirical formulae for unknown metabolites is highlighted, as is co‐expression analysis of transcriptome and metabolome data, as both of these technologies are well suited to this species. The application of the various techniques to study the molecular plant physiology, genetics and functional genomics of Arabidopsis is reviewed, with particular reference to the use of mutants and other genetic resources, such as recombinant inbred lines.
