Field experiments were conducted two consecutive years, in order to investigate runner bean (Phaseolus coccineus L.) cultivated in pure crop system and in intercropping system. To achieve the desired aim, we set the following objectives: study of runner bean plant phenology, study of assimilating pigments content in the runner bean leaves, agro productivity study of runner bean crop, yield of runner bean crop, study of chemical composition of runner bean dry seeds. The studied experimental factor was the trellis system with six variants: (V1) - trellis, with double rows, on individual string, (V2) - trellis, with a single row, on individual string, (V3) - trellis, in a single row, on synthetic net (17 cm mesh), (V4) - intercropping with common maize plants, (V5) - intercropping with sunflower plants, (V6) - intercropping with Jerusalem artichoke plants. Runner bean yield ranged from 3,610 kg ha-1 (V2) to 1,684 kg ha-1 (V6) (first year) and from 3,170 kg ha-1 (V2) to 1,189 kg ha-1 (V6) (second year). Runner bean dry seeds contain: crude protein 22.65% (V6) - 25.47% (V3), crude fat 1.91% (V6) - 2.16% (V4), crude fibre 5.41% (V4) - 5.81% (V5) and nitrogen free extractive substances 62.11% (V3) - 64.92% (V4). The best variant of trellis for runner bean crop was the single row trellis system on individual string and the best intercropping system was intercropping with sunflower.

Runner bean (Phaseolus coccineus L.) offers a great potential as a grain legume in Africa. However, its productivity is low because no improved short-day varieties are available. The aim of this study was to evaluate advanced short-day runner bean lines for high grain yield, resistance to diseases and suitable for cultivation under tropical conditions. F6.8 recombinant inbred lines developed from crosses between local landraces and high yielding imported variety (White Emergo) were evaluated in 2013 and 2014 in a randomized complete block design with three replicates at Kabete (1860 m.a.s.l.) and Ol Joro-Orok (2300 m.a.s.l.) in Kenya. Four local runner bean landraces were used as checks. Analysis of variance showed that there were significant differences for days to flowering, response to diseases and grain yield among the evaluated lines. Improved lines flowered within 49 to 52 days in 2013 and 34 to 58 days in 2014.The improved lines flowered earlier at Kabete than Ol Joro-Orok and showed a higher degree of resistance (scores 1-3) to the major diseases rust, bean common mosaic virus (BCMV) and powdery mildew. The mean grain yield at Kabete was 4,426 kg ha-1 compared to 6,523 kg ha-1 at Ol Joro-Orok giving an average yield advantage of up to 67% compared with local short-day landraces. The results indicated that new high yielding short-day runner bean varieties with resistance to major diseases and tropical adaptation can be obtained from these lines.

Abstract Production of vegetable oils is a vital agricultural resource and oilseed rape (Brassica napus) is the third most important oil crop globally. Although the regulation of lipid biosynthesis in oilseeds is still not fully defined, the acyl-CoA-binding proteins (ACBPs) have been reported to be involved in such metabolism, including oil accumulation, in several plant species. In this study, progressive changes in gene expression in embryos and seed coats at different stages of seed development were comprehensively investigated by transcriptomic analyses in B. napus, revealing dynamic changes in the expression of genes involved in lipid biosynthesis. We show that genes encoding BnACBP proteins show distinct changes in expression at different developmental stages of seed development and show markedly different expression between embryos and seed coats. Both isoforms of the ankyrin-repeat BnACBP2 increased during the oil accumulation period of embryo development. By contrast, the expression of the three most abundant isoforms of the small molecular mass BnACBP6 in embryos showed progressive reduction, despite having the highest overall expression level. In seed coats, BnACBP3, BnACBP4 and BnACBP5 expression remained constant during development, whereas the two major isoforms of BnACBP6 increased, contrasting with the data from embryos. We conclude that genes related to fatty acid and triacylglycerol biosynthesis showing dynamic expression changes may regulate the lipid distribution in embryos and seed coats of B. napus and that BnACBP2 and BnACBP6 are potentially important for oil accumulation.

The 1 M-KOH extract from the depectinated cell walls of parenchymatous tissues of mature runner bean (Phaseolus coccineus) on neutralization, dialysis and concentration gave insoluble (hemicellulose A) and soluble (hemicellulose B) carbohydrate complexes in the weight ratio 2:1. Both fractions contained polysaccharide, protein and polyphenolic material. The structural features of the carbohydrates were examined by methylation analysis. Hemicellulose A contained mainly pectic arabinogalactan, with lesser amounts of arabinoxylan and glucan. Sequential fractionation of hemicellulose B by anion-exchange and hydroxyapatite chromatography gave a range of polysaccharide-protein-polyphenolic complexes. The main polysaccharides in these complexes were (acidic) arabinoxylans, galactans, arabinogalactans 1 and 2 and xyloglucans. The proteins contained small amounts of hydroxyproline, but were rich in aspartic acid and glutamic acid. Attempts to determine the nature of the polyphenolic material were unsuccessful. The structural features of the polysaccharide-protein-polyphenolic complexes are discussed in relation to the structure of the cell walls of parenchymatous tissues.
