A supernodulating mutant isolated from soybean cultivar enrei Symbiotic nitrogen fixation in nodules of legumes depends on the complex interaction between the legume plant and (Brady)Rhizobium bacteria. Nodule formation and nitrogen fixation are closely regulated by both the host plant and the microsymbiont. Plant mutants with altered symbiotic performance are considered to be useful to…

The environmental impact of dairy production: 1944 compared with 2007 A common perception is that pasture-based, low-input dairy systems characteristic of the 1940s were more conducive to environmental stewardship than modern milk production systems. The objective of this study was to compare the environmental impact of modern (2007) US dairy production with historical production practices…

Emerging Fruit Crops Hundreds of fruit species with commercial potential are currently in a status of low economic importance. Some, such as quince, pomegranate, and figs, have been cultivated for thousands of years. Others have only been locally collected and consumed from wild populations of the fruit. The development of these underappreciated crops depends on…

Abiotic stresses and induced BVOCs Plants produce a wide spectrum of biogenic volatile organic compounds (BVOCs) in various tissues above and below ground to communicate with other plants and organisms. However, BVOCs also have various functions in biotic and abiotic stresses. For example abiotic stresses enhance BVOCs emission rates and patterns, altering the communication with…

Ecological consequences of genetic diversity Understanding the ecological consequences of biodiversity is a fundamental challenge. Research on a key component of biodiversity, genetic diversity, has traditionally focused on its importance in evolutionary processes, but classical studies in evolutionary biology, agronomy and conservation biology indicate that genetic diversity might also have important ecological effects. Our review…

Evaluation of salt tolerance in rice genotypes by multiple agronomic parameters The lack of an effective evaluation method for salt tolerance in the screening process is one of the reasons for limited success in conventional salt tolerance breeding. This study was designed to identify useful agronomic parameters for evaluation of salt tolerance and to evaluate…

Agricultural Growth across Crops and Regions: Emerging Trends and Patterns There has been a significant upsurge in the production and productivity growth in Indian agriculture in recent years and it cannot be attributed merely to a favourable weather. On the contrary, it appears that a shift to higher growth path is underway. A far more…

Comparative Transcriptomic Profiling of a Salt-Tolerant Wild Tomato Species and a Salt-Sensitive Tomato Cultivar Wild halophytic tomato has long been considered as an ideal gene donor for improving salt tolerance in tomato cultivars. Extensive research has been focused on physiological and quantitative trait locus (QTL) characterization of wild tomato species in comparison with cultivated tomato.…

The DSSAT cropping system model The decision support system for agrotechnology transfer (DSSAT) has been in use for the last 15 years by researchers worldwide. This package incorporates models of 16 different crops with software that facilitates the evaluation and application of the crop models for different purposes. Over the last few years, it has…

Plant Drought Stress: Effects, Mechanisms and Management Scarcity of water is a severe environmental constraint to plant productivity. Drought-induced loss in crop yield probably exceeds losses from all other causes, since both the severity and duration of the stress are critical. Here, we have reviewed the effects of drought stress on the growth, phenology, water…
