Comprehensive Gene Expression Analysis Of The Nac Gene Family Under Normal Growth Conditions, Hormone Treatment, And Drought Stress Conditions In Rice Using Near-Isogenic Lines (Nils) Generated From Crossing Aday Selection (Drought Tolerant) And Ir64
The NAC (NAM, ATAF1/2 and CUC2) genes are plant-specific transcriptional factors known to play diverse roles in various plant developmental processes. We describe the rice (Oryza sativa) OsNAC genes expression profiles ...
Challenges in the Dryland Agricultural Production Systems of South Asia: Research Priorities and Strategies
Dryland (arid and semi-arid) ecosystems occupy more than 41% of global land area and are home to 2.5 billion people. More than 50% of South Asia’s dryland ecosystems are located in India. Drylands contribute about 40% of ...
Analysis Of Genotypic Variation For Normalized Difference Vegetation Index And Its Relationship With Grain Yield In Winter Wheat Under Terminal Heat Stress
Normalized difference vegetation index (NDVI), which is a measure of leaf greenness (chlorophyll content), is considered to be correlated with crop productivity. This study was conducted to examine genotypic variations for ...
Genetic diversity assessment of Ethiopian tetraploid wheat landraces and improved durum wheat varieties using microsatellites and markers linked with stem rust resistance
A set of 77 markers was used to describe the genetic diversity in a group of 58 tetraploid wheat accessions. Analysis was performed using 31 neutral SSR markers, 31 SSR/STS markers linked with reported major stem rust ...
Global crop improvement networks to bridge technology gaps
To ensure future food security, there is an urgent need for
improved co-ordination of agricultural research. While
advances in biotechnology hold considerable promise,
significant technology gaps exist that may reduce ...
Ad Hoc Modeling in Agronomy: What Have We Learned in the Last 15 Years?
The “Use and Abuse of Crop Simulation Models” special issue of Agronomy Journal published in 1996 ended with the myth of the universal crop model. Sinclair and Seligman consequently recommended tailoring models to specific ...
Farm Restructuring and Land Consolidation in Uzbekistan: New Farms with Old Barriers
In this article we investigate the potential for and limitations of land consolidation as a tool for rural development in transitional environments, focusing on the Khorezm region in Uzbekistan, Central Asia. We frame our ...
Assessing impact of Climatic Variability on Crop Yields in Rajasthan
The paper analyzes yield sensitivity of major rainfed crops namely pearl millet, sorghum and maize to climatic variability in Rajasthan, the driest state of India. The yield time series data for the three selected crops ...
Impact of grazing and tillage on water erosion in northeastern Syria
Impact of grazing and tillage on water erosion under natural rainfall conditions was investigated during the 1994/95 and 1995/96 rainy seasons in the Abd Al-Aziz mountain region, northeastern Syria. The grazing impact was ...
Water and land productivities of wheat and food legumes with deficit supplemental irrigation in a Mediterranean environment
Selecting appropriate crops and applying deficit irrigation can help increase water productivity in waterlimited
regions such as the Mediterranean. The objective of this study was to develop water production
functions of ...
