Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.Over the course of the study, heavy metals (Cr, Cu, Cd, Fe, Zn and Pb) were analysed using Flame atomic absorption spectrophotometer. The assessed mean concentrations of heavy metals follow the trend: Fe > Pb > Zn > Cr > Cu > Cd. A moderate seasonal variation was found among the sampling sites.

Pleiotropic phenotypic effects of the TaCYP78A family on multiple yield‐related traits in wheat
Plant Biotechnology Journal, Volume 22, Issue 10, Page 2694-2708, October 2024.Summary Increasing crop yield depends on selecting and utilizing pleiotropic genes/alleles to improve multiple yield‐related traits (YRTs) during crop breeding. However, synergistic improvement of YRTs is challenging due to the trade‐offs between YRTs in breeding practices.
