Authors: L.M.C. Gomes A.S. Gesteira A.-A.F. de Almeida A.V. de Castro L.O. Dias C.P. Pirovani F.P. Gomes
Sibipiruna (Caesalpinia peltophoroides Benth) is a tree of the Brazilian Atlantic Forest. It is a flowering ornamental tree widely planted throughout Brazil and indicated for restoration of degraded areas. We examined protein profile changes in leaves of seedlings of C. peltophoroides grown in nutrient solution under greenhouse conditions, after exposure .. Read More»

CsSAD: a fatty acid desaturase gene involved in abiotic resistance in Camellia sinensis (L.)
Authors: Z.T. Ding1,2*, J.Z. Shen1,2*, L.L. Pan1,2, Y.U. Wang1,2, Y.S. Li3, Y. Wang4 andH.W. Sun5
Tea (Camellia sinensis L.) is a thermophilic evergreen woody plant that has poor cold tolerance. The SAD gene plays a key role in regulating fatty acid synthesis and membrane lipid fluidity in response to temperature change. In this study, full-length SAD cDNA was cloned from tea leaves using rapid amplification of cDNA ends and polymerase chain reaction .. Read More»

Isolation and in silico functional analysis of MtATP6, a 6-kDa subunit of mitochondrial F1F0-ATP synthase, in response to abiotic stress
Authors: A.A. Moghadam S.M. Taghavi A. Niazi M. Djavaheri E. Ebrahimie
Mitochondrial F1F0-ATP synthase is a key enzymatic complex of energy metabolism that provides ATP for the cell. Subunits of this enzyme over-express under stress conditions. Little is known about the structure and regulatory mechanism of the F0 portion of this enzyme. We isolated the full-length coding sequence of the RMtATP6 gene from rice and wheat, and pa.. Read More»

Computational prediction and experimental validation of a novel miRNA in Suaeda maritima, a halophyte
Authors: S.A. Gharat and B.P. Shaw
The lack of available transcriptome data for plants of no economic or agronomic importance limits the identification of miRNAs in many species. Considering the possible similarity of the transcriptome between related species, the present study used expressed sequence tags (ESTs) of Suaeda salsa and Suaeda glauca to identify conserved miRNAs, which were va..

Regulation of ATG6/Beclin-1 homologs by abiotic stresses and hormones in rice (Oryza sativa L.)
Authors: R.M. Rana S. Dong Z. Ali J. Huang H.S. Zhang
Autophagy, a complex and conserved mechanism, serving as a defense response in all eukaryotic organisms, is regulated by several proteins, among which ATG proteins are the most important due to their involvement in autophagosome formation. ATG6/Beclin-1 proteins, reported to be essential for autophagosome formation and assigned as a conserved domain, were.. Read More»

Overexpression of NaKR3 enhances salt tolerance in Arabidopsis
Authors: Q. Luo1,2, Z. Zhao1, D.K. Li1, Y. Zhang1, L.F. Xie1, M.F. Peng1, S. Yuan3 and Y. Yang1,2
Salinity is a major abiotic stress in agriculture. Here, we report that SODIUM POTASSIUM ROOT DEFECTIVE3 (NaKR3), which encodes a heavy metal-associated domain protein, is involved in salt tolerance in Arabidopsis. The results of quantitative reverse transcription-polymerase chain reaction analysis revealed that NaKR3 was induced by high salinity and osmo.. Read More»

Aluminum triggers broad changes in microRNA expression in rice roots
Authors: J.C. Lima, R.A. Arenhart, M. Margis-Pinheiro and R. Margis
MicroRNAs are small 21-nucleotide RNA molecules with regulatory roles in development and in response to stress. Expression of some plant miRNAs has been specifically associated with responses to abiotic stresses caused by cold, light, iron, and copper ions. In acid soils, aluminum solubility increases, thereby causing severe d.. Read More»

Molecular cloning of a new wheat calreticulin gene TaCRT1 and expression analysis in plant defense responses and abiotic stress resistance
Authors: Y.Q. An, R.M. Lin, F.T. Wang, J. Feng, Y.F. Xu and S.C. Xu
Calreticulin proteins play essential roles in regulating various metabolic processes and in molecular signal transduction in animals and plants. Using homologous PCR, we screened a cDNA library of the wheat resistance gene Yr5 from a near-isogenic line in the susceptible common wheat variety Taichung 29, which was inoculated w.. Read More»

A Cu/Zn superoxide dismutase from Jatropha curcas enhances salt tolerance of Arabidopsis thaliana
Authors: Z.B. Liu, W.J. Zhang, X.D. Gong, Q. Zhang and L.R. Zhou
Superoxide dismutases (SODs) are involved in protecting plants against diverse biotic and abiotic stresses. In the present study, a novel Cu/Zn-SOD gene (JcCu/Zn-SOD) was cloned from Jatropha curcas L. Quantitative reverse transcription-polymerase chain reaction analysis revealed that JcCu/Zn-SOD is constitutively expressed in different tissues of J. curc.. Read More»

Overexpression of a glycine-rich protein gene in Lablab purpureus improves abiotic stress tolerance
Authors: L.M. Yao, Y.N. Jiang, X.X. Lu, B. Wang, P. Zhou and T.L. Wu
Glycine-rich protein (GRP) is involved in the response to abiotic and biotic stresses in plants. A novel GRP gene in Lablab purpureus has been identified. The cDNA of LpGRP was obtained from an SSH library constructed with root tissues of L. purpureus MEIDOU 2012 by waterholding for 10 days. The function of LpGRP was also eval.. Read More»
