Phosphorus （P） is a major limiting factor for plant productivity in many ecosystems and agriculture. The projected increase in atmospheric CO2 is likely to result in changes in plant mineral consumption and growth. We studied P depletion by common bean （Phaseolus vulgaris） cultured hydroponically under ambient （377±77μmol mol^-1） or elevated （650±32 μmol mol^-1） CO2 in media of low or high P. Under elevated CO2 compared to ambient CO2, the maximum P depletion rate increased by 98% at low P and 250% at high P, and P was depleted about 2-5 weeks sooner; leaf acid phosphatase （APase） activity and chlorophyll content both increased significantly; root-to-shoot ratio increased significantly at high P, although it was unaffected at low P; lateral root respiration rate showed no change, suggesting that COs did not affect P depletion via metabolic changes to the roots; the total biomass at final harvest was significantly higher at both low and high P. Our data showed that the increased rate and amount of P depletion during plant growth under elevated CO2 occurred in association with alterations in leaf biochemical properties, i.e., enhanced activities of leaf APase and increased leaf chlorophyll content.

A total of 105 transgenic dce lines independently transformed with a pea ferritin gene （Fer） were previously obtained. After seven generations of selfing and β-glucuronidase （GUS） assisted selection, 82 transgenic lines with stable agronomic traits were got. Among the 82 transgenic lines, two high-iron transgenic rice lines Fer34 and Fer65, with the iron contents in the milled rice being 4.82 and 3.46 times of that of the wild type Xiushui 11, respectively were identified. In the two transgenic lines, the exogenous Fer gene was highly expressed, and inherited as a single locus. The transgene had no negative effect on the agronomic traits of rice plant, other mineral nutritional components, appearance quality and eating quality of the milled rice, indicating that these two lines were elite high-iron breeding lines. Furthermore, the practical application and further studies facilitating utilization of the two elite breeding lines were discussed.

Salt stress is one of the most serious limiting factors for crop growth and production. This study was carried out to evaluate the effects of salt stress in four Mentha piperita L. varieties, in greenhouse conditions. The seedlings were irrigated with 1/2 Hoagland nutrition solutions. Following 10 d of growth in the pots, the seedlings were subjected to salt stress with different concentrations of NaCl （0, 50 and 100 mM, respectively）. Responses of the mint varieties to salt stress were evaluated using some plant growth and physiological parameters, such as plant height, root length, shoot and root fresh and dry weight, and ion concentrations in leaves, such as Na, K, Ca and Cl. Salt stress caused reduction in physiological parameters. However, this reduction was significant at 100 mM NaCl compared to 50 mM NaCl. These two concentrations of NaCl increased Na and Cl contents in leaves. However, K and Ca contents were decreased with salinity. The results showed that Mentha piperita cv. Sewiss and Granada were found more tolerant to salt stress than cv. Marokko and Citaro.

The aims of study were to evaluate growth and characterize the visual symptoms of macronutrient and micronutrient deficiencies in mangosteens. The seedlings were cultivated in nutritive solution containing all required macronutrient and micronutrients and in solutions with omission of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn, using the missing element technique. The experimental design was completely randomized with five replicates and twelve treatments. Symptoms of nutrient deficiency were accompanied by photographic records and described from beginning until complete definition, in which the plants were collected. Growth was evaluated through of dry mass production and nutrient contents. Nutrients omissions resulted in morphological alterations, characteristic symptoms of nutritional deficiency, promoted the reduction in dry mass production in plant, in which the Fe was most limiting, followed by N, and S. Macronutrients and micronutrients contents, without deficiencies (complete treatment) and deficient in mangosteen leaves were respectively: N (16.4 and 12.5 g kg-1);P (1.1 and 0.2 g kg-1);K (10.2 and 8.1 g kg-1);Ca (6.7 and 1.9 g kg-1);Mg (1.1 and 0.1 g kg-1);S (3.0 and 2.2 g kg-1);B (20 and 16 mg kg-1);Cu (7 and 3 mg kg-1);Fe (266 and 86 mg kg-1);Mn (58 and 17 mg kg-1). The decreasing order in appearance of visual symptoms of deficiency was N > S > K > B > Ca > P > Mg > Mn > Cu > Zn.
