Which risk increases when a legume crop's root hairs fail to form a proper infection thread?

💡 Explanation

Limited nitrogen availability increases because the essential symbiosis for nitrogen fixation relies on the root hair infection thread mechanism, enabling rhizobia to colonize root nodules; therefore, without it, atmospheric nitrogen isn't converted, rather than other nutrient deficiencies.
