ریزجانداران خاک علاوه بر افزایش دسترسی و جذب عناصر غذایی مورد نیاز گیاه، توانایی گیاه در مقابله با تنش های زیستی و غیرزیستی را افزایش داده و از این طریق عملکرد گیاه را در شرایط نامساعد محیطی افزایش می دهند. رفتار و عملکرد هر یک از ریزجانداران ریزوسفر می تواند تحت تأثیر عملکرد سایر ریزجانداران تغییر کند. روابط بین ریزجانداران بطور غیر مستقیم باعث تغییر در رشد و عملکرد گیاه می شود. این پژوهش به م...
The present study was carried out to screen and evaluate antimicrobial activity of leaf extracts of Azadirachta indica A. Juss. Petroleum ether, dichloromethane, chloroform, ethanol and aqueous extract of leaves of A. indica were tested against selected Gram positive and Gram negative bacterial species. Phytochemical leaf extracts of A. indica exhibited significant anti-bacterial activity again...
Duchesnea indica (D. indica) is an important traditional Chinese medicine, and has long been clinically used to treat cancer in Asian countries. It has been described previously as a rich source of phenolic compounds with a broad array of diversified structures, which are the major active ingredients.

The larvicidal potential of different solvent crude (hexane, chloroform, ethyl acetate, acetone and methanol) leaf extracts of four plants (Blepharis maderaspatensis, Elaeagnus indica, Maesa indica, Phyllanthus wightianus and Memecylon edule) was tested against the fourth-instar larvae of Aedes aegypti. Insecticidal susceptibility tests were carried out using WHO standard method and the mortali...
Different organic materials possessing antimicrobial properties have the ability to retard nitrification. Nitrification retarders could be successfully used to improve fertilizer efficiency if the retarders do not increase ammonia volatilization as well. The main objective of this study was to find whether any locally available organic materials namely cow dung, seed crush of Syzygium cumini, L...
Diabetes mellitus is a metabolic syndrome characterized by an increase in the blood glucose level. Treatment of diabetes is complicated due to multifactorial nature of the disease. Azadirachta indica Adr. Juss and Bougainvillea spectabilis are reported to have medicinal values including antidiabetic properties.

Chronic hepatitis C virus (HCV) infection is still a global epidemic despite the introduction of several highly effective direct-acting antivirals that are tagged with sky-high prices. The present study aimed to identify an herbal decoction that ameliorates HCV infection. Among six herbal decoctions tested, the Aeginetia indica decoction had the most profound effect on the HCV reporter activity...
Hybrid sterility is a major form of postzygotic reproductive isolation. Although reproductive isolation has been a key issue in evolutionary biology for many decades in a wide range of organisms, only very recently a few genes for reproductive isolation were identified. The Asian cultivated rice (Oryza sativa L.) is divided into two subspecies, indica and japonica. Hybrids between indica and ja...
