Abstract:
... Jatropha curcas is an important economic plant for biodiesel, which is extracted mainly from the endosperm of its mature seeds. Despite the morphological and functional differences between the embryo and endosperm, proteomic characteristics of the two tissues are not yet known. Similar proteomic profiles were observed in the two-dimensional gel electrophoresis maps from the two tissues. There were ...

Abstract:
... Soil carbon sequestration was estimated in a conifer forest and an alpine meadow on the Tibetan Plateau using a carbon-14 radioactive label provided by thermonuclear weapon tests (known as bomb-¹⁴C). Soil organic matter was physically separated into light and heavy fractions. The concentration spike of bomb-¹⁴C occurred at a soil depth of 4 cm in both the forest soil and the alpine meadow soil. Ba ...

Abstract:
... In order to explore the relevant molecular genetic mechanisms of photosynthetic rate (PR) and chlorophyll content (CC) in rice (Oryza sativa L.), we conducted a series of related experiments using a population of recombinant inbred lines (Zhenshan97B x IRAT109). We found a significant correlation between CC and PR (R= 0.19**) in well-watered conditions, but no significant correlation during water ...

Abstract:
... To investigate the genetic basis of drought tolerance in soybean (Glycine max L. Merr.) a recombinant inbred population with 184 F₂:₇:₁₁ lines developed from a cross between Kefeng1 (drought tolerant) and Nannong1138-2 (drought sensitive) were tested under water-stressed and well-watered conditions in field and greenhouse trials. Traits measured included leaf wilting coefficient, excised leaf wate ...

Abstract:
... The aim of the present work was to investigate the effects of osmoconditioning on chilling injury in chilling-sensitive soybean (Glycine max (L.) Merr. Zhonghuang No. 22) seeds during imbibition. Low temperatures reduced the germination rate and no seed germinated at 1 °C. Osmoconditioning of seeds at 20 °C with a polyethylene glycol-8000 (PEG8000) solution at 1.5 MPa for 72 h followed by drying b ...

Abstract:
... Astragalus is a species-rich genus occurring in the western arid habitats in China and its diversification and infrageneric relationships in this region remain unclear. In the present study, based on molecular data, we aim to (i) test whether Phyllolobium (previously treated as a subgenus Pogonophace in Astragalus) should be warranted; and (ii) date the origin of Phyllolobium and probable diversif ...

Abstract:
... In the present paper, we identified and cloned OsDHODH1 encoding a putative cytosolic dihydroorotate dehydrogenase (DHODH) in rice. Expression analysis indicated that OsDHODH1 is upregulated by salt, drought and exogenous abscisic acid (ABA), but not by cold. By prokaryotic expression, we determined the enzymatic activity of OsDHODH1 and found that overproduction of OsDHODH1 significantly improved ...

In vitro variation of B chromosomes was studied by examining the callus cells derived from the immature embryos from a cross of Chinese Spring wheat (Triticum aestivum L.) and Fin 7416 rye (Secale cereale L.) carrying two B chromosomes. In 40-d-old callus cells, the numbers of B chromosomes ranged from one to four in 65.6% of the cells observed. The distribution of B chromosome numbers was associa ...
