# UoH finds gene that helps tomato plants reuse phosphate 2026-10-07T01:27:49+00:00 | Health & Science | Indian Opinion Desk Corroboration: 4 independent outlets Researchers at the University of Hyderabad (UoH) have identified a molecular mechanism that helps tomato plants move stored phosphate from older leaves to younger tissues. The study, published in the Journal of Experimental Botany, was led by Prof Rahul Kumar and Abhishek Roychowdhury, with collaborators from Mendel University and the Spanish National Research Council (CSIC). The team found that the tomato gene SlPAP26b drives phosphate remobilisation. When the gene was silenced, older leaves lost their ability to transfer phosphate, triggering a starvation response in younger leaves and roots even under normal nutrient conditions. The response involved the master regulator SlPHL1 and microRNA miR399, while older leaves remained unaffected, showing that different leaf nodes maintain distinct phosphate signalling mechanisms. The discovery identifies the SlSPX2-SlPHL1 regulatory pathway as a genetic target for improving phosphate use efficiency. Researchers say manipulating this mechanism could lead to resilient crop varieties that reduce dependence on chemical fertilisers, cutting farmer input costs and limiting soil degradation. Update, 7 October 2026: The New Indian Express now also reports the discovery, naming SlPAP26b as the key regulator and adding that the research involved collaborators from Mendel University and the Spanish National Research Council (CSIC). It also specifies that the transcription factors SlPHR1 and SlPHL1 activate the gene by binding to the P1BS element in its promoter. ## Indian Opinion Analysis All four outlets report the same findings from the UoH team, with uniform neutral reporting that sticks closely to the researchers' own statements. Telangana Today and The Hindu present the core discovery concisely, while Deccan Chronicle and New Indian Express add more technical detail, such as the role of SlPHR1 and SlPHL1 in activating the gene and the radioactive phosphorus tracing used to confirm impaired movement. The New Indian Express also names the international collaborators. No outlet adopts a critical or ideological stance. The coverage is straight science reporting, and the differences are only in depth. The researchers have opened a genetic target for crop improvement, but no field trials or regulatory steps are named. The study identifies SlPAP26b as a regulator of internal phosphate use in tomato plants, published in the Journal of Experimental Botany. ## Coverage Coverage: 4 sources, 4 neutral - telanganatoday.com (neutral report) Straight reporting of UoH findings with no added slant - thehindu.com (neutral report) Concise neutral reporting, no editorial comment - deccanchronicle.com (neutral report) Detailed neutral reporting with technical context - newindianexpress.com (neutral report) Straight reporting, adds international co-authors This brief was synthesised by AI from the 4 sources linked above, so one read covers every framing they carry.
