Multiple sequence classes of kinetoplast miniclrcle DNA from Le^iihmar^ia tarentolae were cleaved by mung bean nuclease In the presence of formamide, yielding unit length linear molecules which retained the anomalous electrophoretic mobility in acrylamide characteristic of minicircle DNA. No specific cleavage site sequence common to all minicircle sequence classes was apparent, although the mai...

CLE peptides are key regulators of cell proliferation and differentiation in plant shoots, roots, vasculature, and legume nodules. They are C-terminally encoded peptides that are post-translationally cleaved and modified from their corresponding pre-propeptides to produce a final ligand that is 12-13 amino acids in length. In this study, an array of bionformatic and comparative genomic approach...

BACKGROUND The Bean plataspid (Megacopta cribraria) (Hemiptera: Pentatomidae), native to Asia, is becoming an invasive species in North America; its potential spread to soybean producing areas in the US is of great concern. Ecological niche modelling (ENM) has been used increasingly in predicting invasive species' potential distribution; however, poor niche model transferability was sometimes r...

The genome components of the Melon chlorotic leaf curl virus (MCLCuV) were cloned from symptomatic cantaloupe leaves collected in Guatemala during 2002. The MCLCuV DNA-A and DNA-B components shared their closest nucleotide identities among begomoviruses, at approximately 90 and 81%, respectively, with a papaya isolate of MCLCuV from Costa Rica. The closest relatives at the species level were ot...

BACKGROUND Boreal cropping systems are heavily focused on the production of small-grain cereals; to improve their resilience to climate change and to achieve food and feed security, diversification is needed. This study investigated the potential of faba bean, narrow-leafed lupin and lentil as protein crops in southern Finland, where faba bean is traditional but the other two are novel. RESUL...

The properties of cardiolipin synthase were investigated in mitochondria and submitochondrial fractions from etiolated mung bean (Vigna radiata L.) seedlings. Direct evidence is presented that the enzyme utilizes CDP-diacylglycerol in addition to phosphatidylglycerol for the synthesis of cardiolipin. Cardiolipin synthase had an alkaline pH optimum of about 9 and required divalent cations for ac...

Intercropping, which grows at least two crop species on the same pieces of land at the same time, can increase grain yields greatly. Legume-grass intercrops are known to overyield because of legume nitrogen fixation. However, many agricultural soils are deficient in phosphorus. Here we show that a new mechanism of overyielding, in which phosphorus mobilized by one crop species increases the gro...

The content of indoleacetic acid (IAA) was determined in dry and germinating seeds of French bean (Phaseolus vulgaris), sugar maize (Zea mays), and Scots pine (Pinus silvestris). IAA was found in both the dry and the soaked seeds of the three species examined. The amount of IAA per gram fresh weight was extremely different in the three species whereas the variation between different harvests of...

Vigna reflexo-pilosa, which includes a neglected crop, is the only one tetraploid species in genus Vigna. The ancestral species that make up this allotetraploid species have not conclusively been identified, although previous studies suggested that a donor genome of V. reflexo-pilosa is V. trinervia. In this study, 1,429 azuki bean EST-SSR markers were developed of which 38 EST-SSR primer pairs...
