The Effect Of 4-Chloroindole-3-Acetic Acid On Some Growth Parameters In Mung Bean Under Cadmium Stress, Mohammad Mazid, Barket Ali, Shamsul Hayat, Aqil Ahmad
The Effect Of 4-Chloroindole-3-Acetic Acid On Some Growth Parameters In Mung Bean Under Cadmium Stress, Mohammad Mazid, Barket Ali, Shamsul Hayat, Aqil Ahmad
Turkish Journal of Biology
Seedlings of mung bean (Vigna radiata L. Wilczek) cv. T-44 grown on a sand culture were exposed to cadmium (Cd) (100 µM) on day 10 of growth. These seedlings were subsequently sprayed with deionized water (control) or 4-chloroindole-3-acetic acid (4-Cl-IAA) (10^{-6} M) on day 15 and were sampled 30 days after sowing to assess growth and metabolite content. Growth (length, and fresh and dry mass of roots and shoots) and the level of metabolites (chlorophyll, nitrogen, phosphorus, total sugar, and soluble protein) in the leaves significantly decrease in response to Cd stress; however, the 4-Cl-IAA (10^{-6} M) treatment, both in …
The Genotoxic Potential Of Two Heavy Metals In Inbred Lines Of Maize (Zea Mays L.), Girjesh Kumar, Prashant Kumar Rai
The Genotoxic Potential Of Two Heavy Metals In Inbred Lines Of Maize (Zea Mays L.), Girjesh Kumar, Prashant Kumar Rai
Turkish Journal of Botany
The genotoxic effects of 2 heavy metals (mercury chloride and cadmium chloride) on the gametic cells of 6 inbred lines of maize were tested in terms of cytological abnormalities. Meiosis was normal under control conditions. During the treatments with mercury and cadmium there was a concentration-dependent increase in meiotic abnormalities in all the inbred lines. A wide spectrum of chromosomal aberrations in the treated sets was stickiness, followed by laggards, bridges, scattering, precocious movement, fragments, etc. Maximum chromosomal anomalies were observed in inbred line CM-142 in both the treatment sets of heavy metals. Compared to CdCl_2, HgCl_2 induced more chromosomal …

Cadmium-Induced Antioxidant Status And Sister-Chromatid Exchanges In Vicia Faba L., Serpi̇l Ünyayar, Ayşi̇n Güzel Değer, Ayla Çeli̇k, Fazi̇let Özlem Çeki̇ç, Sertan Çevi̇k
Turkish Journal of Biology
The effects of cadmium (Cd) on antioxidant responses and sister chromatid exchanges (SCE) were studied in Vicia faba L. The activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR), and the levels of ascorbate (ASC), glutathione (GSH), hydrogen peroxide, and malondialdehyde (MDA, indicator of lipid peroxidation) were measured. Genotoxicity was evaluated by measuring the changes in the mitotic index (MI) and sister chromatid exchanges (SCE). Increased activities of SOD and CAT were observed in plants treated with 50 and 100 µM Cd. It was found that APX activity increased remarkably with 50 µM Cd, but …
