Recombination process occurs during meiosis I of cell division results in gene diversity and stability between generations. Biological control relevance: nitrogen fixing, potassium dissolving bacteria and plant growth promoting bacteria have been reported to be much effective and economic than synthetic chemical fertilizers in stimulating plant growth. The promoting effect of biofertilizers has been extensively studied as a way to facilitate in absorbing the required essential minerals or modulating plant hormone levels or for analyzing the inhibitory effects of various pathogens on plant growth and development. However, the stimulatory effect of biofertilizers on genetic variability of cultivated crops as a consequence of meiotic recombination was not extensively studied. The present work aims to study the stimulation effect of biofertilizers on meiotic recombination in diplotene and metaphase I and its extended effect on …
