abstract assessing moisture in the soil under cultivation of crops to achieve high performance and reduced water are necessary. knowledge of the moisture distribution in the root zone, time consuming and costly field tests that simulation models, a suitable alternative in answer to issues of movement and are water distribution. in this study assessment of soil moisture, to aid swap simulation m...

Waitea circinata var. zeae (anamorf Rhizoctonia zeae) is an important pathogen of mainly monocotyledonous plants characterized by its soil-borne nature and capability for the long-term preservation. The host range W. recently expanded to several dicotyledonous crops. latest research conducted in Serbia revealed this as causal agent root neck rot, well plant decay cabbage oilseed at localities F...

Plants can be adapted to the changing environments through tropic responses, such as light and gravity. One of them is root negative phototropism, which is needed for root growth and nutrient absorption. Here, we show that the auxin efflux carrier PIN-FORMED (PIN) 1 is involved in asymmetric auxin distribution and root negative phototropism. In darkness, PIN1 is internalized and localized to in...

S (PH D THESIS) Involvement of auxin distribution in root nodule development of Lotus japonicus (Graduate School of Agriculture, Laboratory of Plant Gene Expression, RISH, Kyoto University) Kojiro TAKANASHI Legumes (Fabaceae) constitute the third largest plant family with around 700 genera and 20,000 species. Legume plants form root nodules through symbiosis with a soil microbe called rhizobia....

In the binary decision diagram–based terminal-pair network reliability analysis, the size of binary decision diagram heavily depends on the chosen edge ordering. From a theoretical point of view, finding the best ordering is an intractable task. Therefore, heuristics have been used to obtain reasonably good orderings. Among them, the breadth-first search heuristic typically outperforms other he...

BACKGROUND AND AIMS Root hydrotropism is a response to water-potential gradients that makes roots bend towards areas of higher water potential. The gene MIZU-KUSSEI1 (MIZ1) that is essential for hydrotropism in Arabidopsis roots has previously been identified. However, the role of root hydrotropism in plant growth and survival under natural conditions has not yet been proven. This study assesse...

Crown imperial scattered according to soil structure and organic matter in Zagros regions in Ilam. This plant has been performed an important role in the beautification of environment, tourist attraction and providing of plant essential oils which are used for the production of medicines. The current research was carried out to evaluation spatial distribution pattern of Fritillaria imperialis i...

In this study the 3-D distribution of centromeres and telomeres was analysed in the interphase nuclei of three Brachypodium species, i.e. B. distachyon (2n=10), B. stacei (2n=20) and B. hybridum (2n=30), which is presumably a hybrid between the first two species. Using fluorescence in situ hybridization (FISH) with centromeric and telomeric DNA probes, it was observed that the majority of B. di...

this paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. for each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...

Branching by de novo formation of lateral roots along the primary root of Arabidopsis seedlings follows a complex longitudinal and transverse pattern. How this pattern is generated is presently under debate. The 'bending hypothesis' proposes that lateral root primordia are initiated by a local accumulation of auxin at the convex side of bends resulting from deflections through obstacles, gravit...
