The positive effect of melatonin on the function of the photosynthetic apparatus is known, but little is known about the specific mechanisms of melatonin's action in plants. The influence of melatonin on chlorophyll metabolism of 24-day-old Pisum sativum L. seedlings during paraquat (PQ)-induced oxidative stress was investigated in this study. Seeds were hydro-primed with water (H), 50 and 200 ...

BACKGROUND AND AIMS Imbibition of Japanese soybean (Glycine max) cultivars was studied using micro-magnetic resonance imaging (MRI) in order to elucidate the mechanism of soaking injury and the protective role of the seed coat. METHODS Time-lapse images during water uptake were acquired by the single-point imaging (SPI) method at 15-min intervals, for 20 h in the dry seed with seed coat, and ...

The balance between mutualistic and antagonistic plant-animal interactions and their spatial variation results in a highly dynamic mosaic of reproductive success within plant populations. Yet, the ecological drivers of this small-scale heterogeneity of interaction patterns and their outcomes remain virtually unexplored. We analyzed spatial structure in the frequency and intensity of interaction...

How the effects of biotic factors are moderated by abiotic factors, and their consequences for species interactions, is generally understudied in ecology. A key abiotic feature of forests is regular canopy disturbances that create temporary patches, or ‘‘gaps,’’ of above-average light availability. Co-occurring in lowland primary forest of Korup National Park (Cameroon), Microberlinia bisulcata...

Background: The mungbean/green gram is one of the major grain legume crops native to Indian subcontinent, which was found damaged extensively by pulse beetle, Callosobruchus maculatus during storage. Moreover, insect damage also causes chemical constituents seeds leading alteration in flavor, nutritive value, marketability and acceptability stored seeds. Therefore, present investigation focused...

Continuous rain and an abnormally wet climate during harvest can easily lead to soybean plants being damaged by field mold (FM), which can reduce seed yield and quality. However, to date, the underlying pathogen and its resistance mechanism have remained unclear. The objective of the present study was to investigate the fungal diversity of various soybean varieties and to identify and confirm t...

Abstract In the initial position in process of roll ginning, seed is drawn to slot contact gap knife-drum due tension fibers. Subsequently, struck with a certain impulse. The separation fibers from after impact beater occurs sequentially, not simultaneously. As result theoretical and experimental studies, optimum frequency shock pulse on ( f = 18-20) was found be most technologically successful...

There are eight species in the genus Phacellaria, six of which are distributed in tropical and subtropical mountain areas of South and Southwest China. The species belonging to this genus are obligate hemiparasites on plants in Loranthaceae and Dendrotrophe (Santalaceae). Based on previously collected specimens, documents and field investigation, we found that Phacellaria is becoming more and m...

The desC gene for the acyl-lipid Delta9-desaturase from the thermophilic cyanobacterium Synechococcus vulcanus was introduced into Nicotiana tabacum under control of the 35S promoter. Expression of the desaturase was confirmed by Western blotting. Lipid analysis revealed that lipid content and the extent of fatty acid unsaturation significantly increased in leaves of transgenic plants. Chilling...

Restoration seedbanks have become a key infrastructure resource in efforts to restore damaged and degraded environments across the globe. Large-scale ecological restoration typically utilizes large volumes of valuable, usually wild-collected seeds, but insufficient knowledge seed biology (including storage requirements some cases) ecology for many species continues hamper utility meet this risi...
