Cloning and expression of the 1-aminocyclopropane-1-carboxylic oxidase gene from Agrostis stolonifera
Authors: G.Z. Xiao, L.J. Li, K. Teng, Y.H. Chao and L.B. Han
A gene encoding 1-aminocyclopropane-1-carboxylic oxidase (ACO), which catalyzes the terminal step in ethylene biosynthesis, was isolated from Agrostis stolonifera. The AsACO gene is composed of 975 bp, encoding 324 amino acids. Three exons interspersed by two introns form AsACO gDNA. A BLAST search of the nucleotide sequence r.. Read More»

Phosphate-induced-1 gene from Eucalyptus (EgPHI-1) enhances osmotic stress tolerance in transgenic tobacco.
Authors: A.O. Sousa, E.T.C.M. Assis, C.P. Pirovani, F.C. Alvim and M.G.C. Costa
Environmental stresses such as drought, freezing, and high salinity induce osmotic stress in plant cells. The plant response to osmotic stress involves a number of physiological and developmental changes, which are made possible, in part, by the modulation of the expression of specific genes. Phosphate-induced-1 gene (PHI-1) w.. Read More»

Genome-wide identification and expression analysis of CIPK genes in diploid cottons
Authors: J.J. Wang, X.K. Lu, Z.J. Yin, M. Mu, X.J. Zhao, D.L. Wang, S. Wang, W.L. Fan, L.X. Guo, W.W. Ye and S.X. Yu
Calcineurin B-like protein-interacting protein kinase (CIPK) plays a key regulatory role in the growth, development, and stress resistance of plants by combining with phosphatase B subunit-like protein. In the present study, CIPK genes were identified in the whole genomes of diploid cottons and their sequences were subjected t.. Read More»

Expression of LTP genes in response to saline stress in rice seedlings
Authors: G.P. Moraes, L.C. Benitez, M.N. do Amaral, I.L. Vighi, P.A. Auler, L.C da Maia, V.J. Bianchi and E.J.B. Braga
Saline stress is one of the primary factors limiting increased rice productivity in the southern region of Brazil. Farming can be affected by salinity that is due to both the origin of the soils as well as the irrigation water. Lipid transfer proteins (LTPs) have many physiological functions, including in the response to saline stress. Therefore, the obje.. Read More»

Expression of genes related to tolerance to low temperature for maize seed germination
Authors: I.C. Silva-Neta, E.V. Pinho, A.D. Veiga, R.G. P�¬nho, R.M. Guimar�£es, F. Caixeta, H.O. Santos and T.L. Marques
The aim of this study was to characterize maize lines tolerant to cold temperatures during the germination process. Seeds from lines with different levels of tolerance to low temperatures were used; 3 lines were classified as tolerant and 3 as susceptible to low germination temperatures. A field was set up to multiply seeds from selected lines. After the .. Read More»

Screening of inbred popcorn lines for tolerance to low phosphorus
Authors: O.J.A.P. Santos, L.S.A. Gon�§alves, C.A. Scapim, de S.M. de Sousa, C.R. Castro, V. Y. Baba and A.L.M. de Oliveira
Increasing phosphorus use efficiency in agriculture is essential for sustainable food production. Thus, the aims of this study were: i) to identify phosphorus use efficiency (PUE) in popcorn lines during the early plant stages, ii) to study the relationship between traits correlated with PUE, and iii) to analyze genetic divers..

Variation in cassava germplasm for tolerance to post-harvest physiological deterioration
Authors: M.T. Venturini, L.R. Santos, C.I.A. Vildoso, V.S. Santos and E.J. Oliveira
Tolerant varieties can effectively control post-harvest physiological deterioration (PPD) of cassava, although knowledge on the genetic variability and inheritance of this trait is needed. The objective of this study was to estimate genetic parameters and identify sources of tolerance to PPD and their stability in cassava acce.. Read More»

A comparative study of stress-related gene expression under single stress and intercross stress in rice
Authors: Y.P. Zhang, Z.G. E,H. Jiang,L. Wang,J. Zhou and D.F. Zhu
Plant hormones play important roles in the crosstalk between biotic and abiotic stresses in rice throughout its entire growth period. However, these interactions are not completely understood. In this study, the physiological performance of rice seedlings under a single stress and a sequential combination of various stresses (intercross stress) was determ.. Read More»

OsMYB511 encodes a MYB domain transcription activator early regulated by abiotic stress in rice
Authors: P. Huang, H. Chen, R. Mu, X. Yuan, H.S. Zhang and J. Huang
The MYB-domain proteins exist universally across diverse organisms and regulate numerous processes during the plant life cycle. In the present research, a full-length MYB gene OsMYB511 was identified from rice seedlings through microarray data. Induction of OsMYB511 by cold stress was dramatic in japonica cultivar Jiucaiqing as compared to indica IR26. In.. Read More»

Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two differ.. Read More»
