Multiscale control of vegetation patterns: the case of Doñana (SW Spain)

The early studies about the plant ecology of Doñana carried out at a small scale showed that the main process controlling vegetation composition of the stabilized dunes was soil water availability. However, the extrapolation of this model to larger spatial scales failed to explain observed vegetation patterns. In this work, the vegetation patterns and the processes causing them are studied at a larger scale. Data of topography, soil pH, electrical conductivity, and available iron allowed to distinguish three large geomorphologic zones on the stabilized dunes of the Doñana Biological Reserve which correspond to different dune building episodes. Different dune episodes showed differences in both water table depth and dynamics, which are due to groundwater flow systems of different scale. It is further manifested by differences in shrub composition. The results show that geomorphology controls the vegetation pattern at different scales mediated through water availability. Differences in water availability are due to the connection to groundwater flow systems of contrasted scale. On a small scale (10−10² m), along dune slopes, there is a gradient from dune ridges to slacks, from xerophyte to hygrophyte vegetation types. On a mesoscale (10²−10³ m), there are several dune episodes with variable topographic altitude, dominated by different types of xerophytes. On a regional scale (>10³ m), the discharges of the regional aquifer produce strong environmental and biotic stresses resulting in a mixed community.

Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Branching and Growing of Apple Sapling

According to the control, applications increased sapling height and this increasing was found important as statistically. Generally, bacteria applications more increase than Perlan on sapling height. Effect of bacteria and Perlan applications on sapling diameter showed different in cultivars and years. Generally, sapling diameter was increase by applications. Applications that on branching was important in 2009, but not important in 2010 as statistically. The most effective applications on branching were T8 and BA-8+T8 in ‘Granny Smith’, in ‘Red Delicious, Red Chief’ BA-8+T8 and BA-8, in ‘Fuji’ Perlan and BA-8 in 2009. Effect of applications on lateral branch degree was different in years and cultivars. According to the control, bacteria and Perlan applications raised length of lateral branch also bacteria was more effective than Perlan.Finally, plant growth promoting bacteria more increased branching and sapling quality than Perlan.     

Analysis of differentially expressed proteins in the pollen of Malus spectabilis (crabapples) and Malus domestica (‘Gala’ apples) and their role in pollination

Our objective was to study the differentially expressed proteins (DEP) in various Malus spectabilis (crabapple) varieties (M. ‘Snowdrift’, M. ‘Hongling’ and M. ‘Hongjin’) in relation to Malus domestica (‘Gala’) and their role in pollination. Our method used a two-dimensional electrophoresis (2-DE) to analyse the differential proteins in the pollen of several crabapples. The 2-DE apples combined with the tandem mass spectrometry (MS-MS) and protein database retrieval helped us to identify the nature and function of DEPs in ‘Gala’ apples and crabapples. We identified 1195 proteins through 2-DE. Among these, six DEPs, namely chloroplast ferritin, Actin, Beta-fructofuranosidase, vacuolarH+-ATPase catalytic subunit, Full = Phosphoglucomutase, and Cytochrome b were identified by MS-MS. This study identified six DEPs among the pollen from the ‘Snowdrift’ crabapple, ‘Hongling’ crabapple, ‘Hongjin’ crabapple, and ‘Gala’ apples. The DEPs included metabolism related proteins, stress/regulatory proteins, and proteins involved in signal transduction.

Phenology of strawberry guava (Psidium cattleianum) in ReÂunion Island

Summary

The phenology of wild stands of strawberry guava (Psidium cattleianum Sabine) was studied at 100, 480 and 720.m over 2 years in ReÂunion Island. The shoots bore flower buds at the basal nodes, and vegetative buds at the apical nodes. Trees produced vegetative growth from September to December, flowers from November to January and fruit from February to June. Shoot growth was earlier at 100 and 720.m the first year, but were synchronized in the second year. Flowering and fruiting were also earlier at 100.m. The intervals between shoot emergence and flowering, and flowering and fruit maturity were strongly related to temperature, with base temperatures of 5.58C and 2.68C, and heat units requirements of 675 and 2,5528C.d, respectively. The number of shoots, flowers and fruit per branch varied across sites and years, unrelated to temperature. However, production was significantly higher at 720.m. Production was much lower after a hurricane. Flowering (y) was related to shoot production per branch (x) (log(y)=111.33.log(x); r².=.0.78), whereas the fruit set rate was highly variable between trees (26±100%). The number of fruits per branch (1±6) was possibly related to poor shoot growth or fruit set, but unrelated to the timing of the phenological events. It is expected that commercial orchards would be more productive than feral stands.

Effect of nitric oxide on dormancy release in bulbs of Oriental lily (Lilium orientalis) ‘Siberia’

SUMMARY

Nitric oxide (NO) is an essential endogenous plant signalling molecule involved in a wide range of plant developmental processes. To investigate the effect of NO on breaking dormancy in bulbs, bulbs of Oriental lily (Lilium orientalis) ‘Siberia’ were treated with various concentration of the NO donor, sodium nitroprusside (SNP; 0.0,1.0,3.0, or 5.0 mM). The results showed that the effect of NO was dose-dependent, with the maximum biological response at 1.0 mM SNP. When applied exogenously, the 1.0 mM SNP treatment reduced the time required to release dormancy in Oriental lily bulbs. Meanwhile, 1.0 mM SNP significantly increased the shoot length:bulb height ratio. In addition, 1.0 mM SNP significantly lowered starch concentrations and increased water soluble carbohydrate (WSC) and reducing sugar concentrations. These results indicate that NO treatment, at the correct dose, reduced the time required to release dormancy in bulbs by accelerating the degradation of starch and increasing the accumulation of WSC and reducing sugars in Oriental lily bulbs.     

Construction of recombination vector of pcDNA3.1(+)-MER-Syk（L）and the effect of Syk(L) on the proliferation of breast cancer cells

AIM: To explore the effect of 4-hydroxytomacifen (4-OHT) on MER-Syk(L) cellular localization and the function of Syk(L) on cell proliferation in breast cancer cells.METHODS: pcDNA3.1(+)-MER-Syk(L) vector was constructed and the cell line MDA-MB-231, which expressed MER-Syk(L) stably, was established. Western blotting and immunofluorescence techniques were used to detect localization of MER-Syk(L) fusion protein in MDA-MB-231 cells cultured with or without 4-OHT. MTT assay was used to explore the proliferation ability of MDA-MB-231 stable cells.RESULTS: (1) MER-Syk(L) fusion protein, not MER-Syk(S) and MER protein, translocated from cytoplasm to nucleus in the presence of 4-OHT. (2) Nuclear not cytoplasmic MER-Syk(L) fusion protein inhibited MDA-MB-231 stable cell growth. (3) With or without the treatment of 4-OHT, MER-Syk（S）and MER protein always located in cytoplasm and did not suppress cell growth.CONCLUSION: With 4-OHT, MER-Syk(L) fusion protein translocates to nucleus and inhibits cell growth.
