background & aim: deanaie thyme (thymus daenensis celak.), a member of the lamiaceae family.  thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant activities. experimental: ...

MicroRNAs (miRNAs) play vital regulatory roles in plant growth and development. The phase transition from vegetative growth to flowering is crucial in the life cycle of plants. To date, miRNA-mediated flowering regulatory networks remain largely unexplored in radish. In this study, two small RNA libraries from radish leaves at vegetative and reproductive stages were constructed and sequenced by...

During the transition from vegetative to reproductive growth, the shoot meristem of flowering plants acquires the inflorescence identity to generate flowers rather than vegetative tissues. An important regulator that promotes the inflorescence identity in Arabidopsis is AGAMOUS-LIKE 24 (AGL24), a MADS-box transcription factor. Using a functional estradiol-inducible system in combination with mi...

Knowledge on habitat characteristics and nature of regional vegetation inrangelands is a prerequisite for any planning and proper range management along withsustainable development of renewable natural resources. Rangelands in southern andwestern highlands of Kashan, Iran are of good vegetation diversity but unfortunately,palatable and desirable species are endangered in recent years. This rese...

in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...

BACKGROUND MicroRNAs (miRNAs) is a class of non-coding RNAs involved in post- transcriptional control of gene expression, via degradation and/or translational inhibition. Six-hundred sixty-one rice miRNAs are known that are important in plant development. However, flowering-related miRNAs have not been characterized in Oryza rufipogon Griff. It was approved by supervision department of Guangdon...

Range forage of Vicia variabilis, Astragalus spp., Medicago sativa, Prangos uloptera and Sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in Chaharmahal and Bakhtiari province, Iran. Samples were analyzed for the determination of Crude Protein (CP%), Ether Extract (EE), Crude Fiber (CF), total Ash, Neutral Detergent Fiber (NDF), Acid Detergen...
