Oxygen limiting conditions are a common occurrence in root zones of most crop plants and can adversely affect nearly all aspects of plant growth and development including its survival. The objective of this study was to determine the effectiveness of a novel redox cycling agent, vitamin K3, and various peroxides including hydrogen peroxide, calcium peroxide and magnesium peroxide in alleviating the effects of hypoxia in bean seedlings grown in nutrient culture. All the anti-hypoxic agents including vitamin K3 had a positive impact on the overall growth of bean seedlings under hypoxic conditions, but their responses were variable depending on the concentration. With regard to shoot growth, vitamin K3 (5 μM) increased the leaf area significantly, by more than 58% over the hypoxic control plants and produced the highest stem fresh weight similar to calcium peroxide (20 μM) and magnesium peroxide (10 μM). In addition, the use of vitamin K3 resulted in the highest accumulation of chlorophyll (chla + chlb) in the leaves, an increase of nearly two-fold over the hypoxic control plants. Furthermore under hypoxia, calcium peroxide (20 μM) and magnesium peroxide (10 μM) produced the highest leaf biomass (FW) followed by vitamin K3. Vitamin K3 (1 μM) also favored root growth in bean seedlings under hypoxia;it produced the largest increase in root length and root biomass (DW) similar to calcium peroxide and magnesium peroxide. Based on the overall shoot and root growth response of bean seedlings to various anti-hypoxic substances under hypoxic conditions, calcium peroxide, magnesium peroxide and vitamin K3 performed better than hydrogen peroxide. These findings show that vitamin K3 and peroxide salts are effective in alleviating hypoxic stress in bean seedlings and also, further highlight their potential for dealing with hypoxia in wide ranging situations.

Nutritional and Mineral Variability in 52 Accessions of Common Bean Varieties(Phaseolus vulgaris L.)from Madeira Island

The Phaseolus vulgaris L. is one of the traditional and most important leguminous crops in the Island of Madeira. The island’s bioclimatic tiers, agro-ecological environment and traditional farming practices had a great influence on the evolution of regional bean landraces. The variability of the nutritional and mineral seeds composition of 59 accessions of the Madeiran landraces, standard and commercial varieties was evaluated. Wide ranges of variability in biochemical parameters were reported among the Madeiran landraces, being the best sources of protein and mineral nutrition, according to the statistical results and literature comparative evaluation. Specifically, the content (g per 100 g DW) of ash ranged from 3.64-5.67, lipids from 0.57-2.86, protein from 18.55-29.69, starch from 23.40-52.65, soluble sugars from 2.97-6.84, while content of dry matter was from 83.35-93.55. The seeds also contained (per 100 g DW) between 2.55-4.83 g N, 0.30-7.50 g P, 1.30-2.49 g K, 0.10-0.18 g Mg, 4.10-10.00 mg Fe, 50.0-1.40 mg Cu, 2.20-5.00 mg Zn, 0.90-3.80 μg Mn and 0.20-2.40 μg B. This variability implies that the screened germplasm could serve as a source for breeding new varieties with improved biochemical and nutritional traits or could be highly recommended to meet specific dietary requirements. The cultivar Vaginha Grossa (ISOP 713) revealed low carbohydrate content that could be a good food choice for diabetics, while cultivar Vermelho (ISOP 724) bean should be offered as a valuable alternative source of protein and minerals in the local diet.

<i>Phaseolus</i>Genetic Resources Grown in Campeche, Mexico

The protein intake of the population in the Yucatan Peninsula is based upon the different forms of beans naturally developed. The different ecotypes of creole beans that are grown traditionally have been displaced by improved varieties, thereby turning into a risk of losing a valuable source of germ-plasma. The present study is aimed to identify, collect and preserve several bean species genetic resources grown in Campeche, Mexico, in addition to the development of an identification card with the main phenotypic characteristics and yield components. A total of 33 different samples were collected from nine different municipalities statewide;out of those, 15 were Phaseolus vulgaris and 18 Phaseolus lunatus. The collected samples diversity is reflected in the range of growth habits from the bush to the indeterminate climbing species, being these the most representative with about 29 samples, many of those because of the way the planting is carried out, which is traditionally performed in association with the cultivation of corn. Early samples were identified in this diversity with their cycle ranging from 60 to 120 days after emergence. Samples of Phaseolus lunatus with 1.35 to 2.86 t/ha yield potential were also obtained.

Chinese Science Bulletin 1988年第3期33卷 231-235页

作者：王育东阎隆飞 Laboratory of Biochemistry Beijing Agricultural University

The membranes of animal cells, especially those of human red cells, have been intensively studied. It has been demonstrated that there is a membrane skeleton on the inside of the red cell membrane. The membrane skeleton is composed of membrane proteins such as spectrin, ankyrin and actin. The presence of a similar membrane skeleton in other animal cells was reported also.
