Authors describe performance of Tospovirus-resistant tomato varieties under commercial production settings in Dade County, FL. Virus resistance has become important for this area since the emergence of two new tomato-infecting tospoviruses. Knowledge of availability and performance of resistant varieties will help growers who are looking for alternative varieties.

Cultural Requirements

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.

Oriented Approach

The Gujarat Narmada Valley Fertilizers Company Ltd (GNFC), a giant fertilizers and chemicals complex, owns the world's largest single stream ammonia and urea plants, and is located in the predominantly backward area of Bharuch District in Gujarat State, India. The company began commercial production on 1st July 1982. GNFC's performance as regards both capacity utilization and pollution control, has been good right from commissioning. Concerning pollution control, the company has adopted a productivity oriented approach which is entirely different from the usual ‘policeman' approach or ‘problem' approach. The company decided to find applications for each of the pollutants. Regarding liquid effluents, the company has successfully concluded a number of research and development projects as a result of which nearly 71% of the total volume of liquid effluent is put to productive use. This has helped the company to reduce the fresh water intake by about 18,000 m3/day (much more than the total volume of fresh water required by the whole of Bharuch city!). The remaining volume (29%) leaving GNFC premises completely conforms to irrigation standards and has been utilized by farmers for the last 5 years. This has resulted in a ‘mini green revolution' in the water-scarce area of Bharuch District. Since the entire effluent is either being recycled within the company or being used by farmers, the company has reached a stage of ‘zero effluent'. The company has also saved more than US$ 500,000 to date, by properly managing liquid effluent.

AbstractPhosphorus (P) is an essential nutrient for marine phytoplankton. Maintaining intracellular P homeostasis against environmental P variability is critical for phytoplankton, but how they achieve this is poorly understood. Here we identify a SPX gene and investigate its role in Phaeodactylum tricornutum. SPX knockout led to significant increases in the expression of phosphate transporters, alkaline phosphatases (the P acquisition machinery) and phospholipid hydrolases (a mechanism to reduce P demand). These demonstrate that SPX is a negative regulator of both P uptake and P-stress responses. Furthermore, we show that SPX regulation of P uptake and metabolism involves a phosphate starvation response regulator (PHR) as an intermediate. Additionally, we find the SPX related genes exist and operate across the phytoplankton phylogenetic spectrum and in the global oceans, indicating its universal importance in marine phytoplankton. This study lays a foundation for better understanding phytoplankton adaptation to P variability in the future changing oceans.
