Asiatic citrus canker is a devastating disease resulting in drastic economic losses in citriculture worldwide. Amongst three different types of the disease, i.e. A, A* and A^w, the A* type is genetically less known. In order to comprehend the behavior of the Asiatic citrus canker A*-type strain (Xanthomonas citri subsp. citri) in the vicinity of the host cells, a targeted semi-quantitative transcript analysis approach via RT-PCR was carried out. A subset of sixteen genes, as representative of different steps involved in phytopathogencity, was analyzed on the culture medium (as uninduced) and compared with the subset isolated from the infected Mexican lime (Citrus auarntifolia L.) plants (as induced). The results showed that certain genes were up-regulated in induced condition, suggesting a putative role in bacteria-host interaction. Furthermore, the transcripts in induced condition could be classified into constitutive, early- and late-responsive genes, demonstrating their functional relevance during the host-pathogen interaction.

Ambiguity is one of the characteristics of some prominent contemporary poems and it is achieved by inducing original and preconceived concepts. One of the functions of such ambiguity is to create a sense of suspense. Suspension is a form of waiting in which the narrator puts the audience in a conscious and purposeful state of doubt and ignorance of the result of the narration, but with the help of linguistic elements, provides the possibility of thinking, predicting and discovering the missing link in poetic propositions. Creating a sense of suspense for the audience for understanding the meaning and purpose of the narrator creates a passion for reading. The reader's curiosity, along with the presuppositions, preconceptions, and possibilities that occur during the suspension, reproduces the meaning.
In this article, after examining linguistic and editorial factors of suspension, such as unfamiliar words, multilingualism, the existence of new terms, the use of new and native words, archaism, specialized terms, deletion, pronoun displacement, editorial aberrations, etc. we will analyze how do contemporary poets use these factors to create suspension with functions such as highlighting, defamiliarization, modernity, semantic development, polysemy, brevity, conveying the themes of indigenous culture, linguistic development and richness, so that they can engage the audience in the narrative.

Abstract
 Introduction: In the past decade, planning at different levels, especially at the regional development, has experienced different ideas of organization of product activity. Industrial cluster concept on cooperation among manufacturing firms are proximity to one another. The trace of this concept can be found in the theories of industrial planning. It is what distinguishes the concepts, the impact of industrial clusters on various sectors of the economy, named economic planning; and to interact on regional spatial development, named spatial planning.
 Methodology: Little attention has been paid by interdisciplinary scientists to this view of the industrial cluster; and researchers have been associated with regional development. This thesis is aimed to determine the role of industrial clusters in regional spatial development and the role of spatial development in optimizing the production of industrial cluster. Also,  the attempt is to interact between physical, social, economic factors and spatial development of regional industrial cluster. In general, industrial clusters within its definition set priorities on two concepts: 1. The geographical concentration of companies and institutions; and 2. Cooperation of product activities. So, companies, to achieve concepts, benefit values through activities of the production process. Michael Porter named it as value chain. These activities can generally be divided in two categories. The first category is called a primary activities, such as operations, marketing and sales, inbound/outbound logistic and services; and the second category is named support activities, such as procurement, technology development, human resource management, firm infrastructure
 Results and discussion: Thus, the principal foundation of industrial clusters, resulting results in the value chain of operations in the value chain as primary activity and interacts to procurement, technology development, human resource management, firm infrastructure as support activities.  Need to emphasize supply elements in mechanisms of growth changed regional growth models, and intra-regional flows of the resources (of capital and labor) are elements of the model. These models were developed in two main directions: 1. Focused on endogenous growth elements; 2. In addition to the resources of production (capital and labor), it seeks to engage the other factors of production, such as infrastructure and accessibility.
Conclusion: Thus, in the context of spatial development of the region, the five processes that are named competitive, spatial, social, interactive and endogenous processes production as space on the production of industrial clusters at region interact to in value chain. In strategic planning, SWOT is applied in regional spatial planning that use on industrial clusters by three stages: 1. To decide the system of spatial planning and its environment; 2. To develop a systematic framework for analysis; and 3. Proposal of possible strategic options. Within results of  SWOT, strategy statement of regional spatial development of Sari County based on industrial cluster provides a tool for guiding and restraining forces, trends and processes affecting the spatial development. This statement contains a hierarchy of goals, objectives, and strategies, and policies. These are as alternative paths of action and attempt to provide the ideal model of regional spatial planning based on industrial cluster.
