| 英文摘要 | AimsPlants are capable of detecting the genetic identity of neighboring individuals, responding through either advantages of kin recognition (kin selection theory) or competitions under resource limitations (niche partitioning theory). While morphological responses such as root allocation and biomass changes are well studied, little is known about how kin recognition affects functional traits like nitrogen (N) uptake strategies.MethodsWe conducted a microcosm experiment using Brassica juncea individuals from six maternal families and applied in situ15N labelling to test whether kin recognition influences plant growth and N uptake strategies. Each family was paired both with siblings (same maternal family) and strangers (different maternal families), with two seedlings per pot. Biomass responses and N uptake of inorganic N (NH4+ and NO3-) were quantified.ResultsPlants grown with strangers showed increases in biomass response ratio (49% in shoots and 79% in roots) but did not significantly differ in absolute biomass compared to sibling-grown plants. In contrast, N uptake rates, particularly for NO3-, were significantly higher in sibling-grown plants. Sibling-grown plants exhibited a stronger uptake preference for NO3- (76%), whereas stranger-grown plants showed a shift toward NH4+. The magnitude of kin recognition effects on N uptake varied across maternal families, with one single family showing a strong genotype-specific response.ConclusionOur study demonstrates that kin recognition in B. juncea modulates N uptake strategies, with sibling-grown plants preferentially for NO3- uptake while stranger-grown plants shift toward NH4+. These effects vary among maternal families, revealing genotype-specific responses in nutrient foraging behavior. |
