Biochemical and molecular adaptation of rice plants towards low phosphate condition

Rice is the staple food for half of world's population. Phosphorus an essential element rice plant growth, development and production; however, availability soluble phosphate uptake often limited due to binding with cation in different pH environments. Therefore, varieties, which can grow well under a environment, urgent need agricultural biotechnology. This study reported two contrasting varieties' biochemical molecular adaptation toward low medium. The results show that response these varieties genotype-dependent. We observed higher use efficiency low-Pi-sensitive G299 variety than low-Pi-tolerant G22 variety. Moreover, expression five out six investigated genes relating Pi responsive pathway, including purple acid phosphatase (PAP), starvation 2 (PHR2), SPX (SYG1/PHO81/XPR1) domain-containing gene, transcription factor 1 (PTF1) (PHO1) were significantly accession tolerant genotype. Impressively, 214 times more PHO1 was leaves variety, followed by SPX, PTF1, PHR2, PAP21 genes. Similarly, induced at highest level roots PAP21, SPX1 These findings supply further information elucidation mechanism behind plants medium nutrient happy varieties.
