Genetic Evaluation for Effects of Salt and Drought Stress on Growth Traits of Zea mays Seedlings
Authors: M. Khalil, M.S. Rashid, Q. Ali and A. Malik
Maize is an important grain cash crop grown throughout the world for its grain and fodder. It is highly sensitive for abiotic stress conditions; like drought, chilling, alkalinity, heat, salt and cold conditions. Present study was carried out to find out the effects of salt or NaCl and drought stress on three selected maize genotypes viz., P6103, L5971 an.. Read More»

Evaluation of Genetic Variability in Wheat and Maize under Heavy Metal and Drought Stress
Authors: M. Tahir, M.S. Rashid, Q. Ali and A. Malik
There are certain conditions which cause a change in the growth pattern of plants. These circumstances are significantly effective in growth and cultivation of major crops. The effects of higher levels of copper sulphate through fertilizers can be effective in reducing the growth of a healthy plant. An experiment was conducted in the greenhouse of Institu.. Read More»

Genetic Evaluation of Brassica juncea and Sinapis alba Seedling Traits under Multi Stress Conditions
Authors: H. Khan, M.S. Rashid, Q. Ali and A. Malik
Brassica is an important oil seed crop plant species grown throughout the world. Brassica juncea and Sinapis alba are very sensitive to abiotic stress conditions which included drought, heat, salt, heavy metals and cold which disturb their growth and yield. For this purpose to check the effect of heavy metals, salt and drought, an experiment was conducted.. Read More»

Morphological and molecular characterization of maize inbred lines showing variability for drought tolerance
Authors: Asima Gazal, F.A. Nehvi, Ajaz Ahmad Lone, Zahoor Ahmed Dar
A set of hundred maize inbred lines were analyzed for resilience to moisture stress for twenty-four traits related to maturity, morphological, physiological, yield, quality and root traits. Evaluation confirmed a wide range of variability revealing significant response of main effects (lines, irrigations and years and their re.. Read More»

Marker-Assisted elimination of drought-susceptible accessions in upland rice breeding
Authors: Ariadna Faria Vieira, Gabriel Feresin Pantali�£o, Fernanda Martins Abreu, Ricardo Dias Silveira, Ana Letycia Basso Garcia, Leandro Gomide Neves, Rosana Pereira Vianello, Adriano Pereira Castro, Claudio Brondani
Breeding for water-deficit tolerance is fundamental to guarantee the sustainability of upland rice production, mainly due to the possibility of an increased frequency of drought episodes due to climate change. This work aimed to identify single nucleotide polymorphism (SNP) markers, derived from RNA sequencing (RNA-Seq), genom.. Read More»

Ectopic Expression of AtCIPK23 Enhances Drought Tolerance via Accumulating Less H2O2 in Transgenic Tobacco Plants
Authors: Liming Lu, Linglong Yang, Ke Li, Yifei Lu, Liqin Li
Drought is a major threat to agricultural crop growth and productivity. However, the molecular mechanism behind such effects remains largely unknown. Plant CBL (Calcineurin B-Like)-interacting protein kinases (CIPKs) are believed to play an important role in plant drought tolerance and signalling transduction. Here, we report .. Read More»

Performance of grain sorghum hybrids under drought stress using GGE biplot analyses
Authors: P.S.C. Batista, C.B. Menezes, A.J. Carvalho, A.F. Portugal, E.A. Bastos, M.J. Cardoso, C.V. Santos and M.P.M. Julio Centro de
The objective of this study was to estimate the adaptability and stability of grain sorghum hybrids grown under post-flowering water stress and non-stress conditions. The trials were carried out in Nova Porteirinha-MG during the season of 2014 and 2015, and in Teresina-PI in the 2014 season. Twenty-nine-grain sorghum hybrids w.. Read More»

Cloning and functional characterization of the HbSYR1 gene encoding a syntaxin-related protein in Tibetan hulless barley (Hordeum vulgare L. var. nudum HK. f.)
Authors: Q.J. Xu, Y.L. Wang, Z.X. Wei, H.J. Yuan, X.Q. Zeng and N. Tashi
Tibetan barley is a staple food for the natives of Qinghai-Tibet Plateau. Drought causes a reduction in barley production. In this study, the full-length cDNA of a gene encoding a syntaxin-associated protein was cloned from the leaves of a drought-resistant variety of barley, “Himalaya 10”; its expression was evalu..

Gas exchanges and water use efficiency in the selection of tomato geno-types tolerant to water stress.
Authors: M.E.A. Borba, G.M. Maciel, E.F. Fraga Junior, C.S. Machado Junior,G.R. Marquez, I.G. Silva and R.S. Almeida
Water stress can affect the yield in tomato crops and, despite this, there are few types of research aiming to select tomato genotypes resistant to the water stress using physiological parameters. This experiment aimed to study the variables that are related to the gas exchanges and the efficiency in water use, in the selectio.. Read More»
