ABSTRACT
It is well established that plants can communicate with each other under different stressful conditions through (signals, cues, and rhizosphere interactions). Numerous studies have been conducted to find how plants respond to different neighbors at various points of genetic affiliation. Contrasting results and lack of molecular evidence in species recognition studies have made this topic more curious and complex. Some plant species compete more vibrantly for below-ground resources when an encounter with neighboring unrelated conspecifics as compared to related conspecifics (kin recognition). Some species increase competition when interacting with related and unrelated conspecifics (niche partitioning); some species do not show any change in the above/below ground allocation pattern. In this review, we attempt to provide a research background of species recognition in plants and plant communication, the current state of knowledge, and future perspectives. It has been established that species identification and communication between plants exist through many mediums like damage induced warnings, call for predators, root secretion, and volatile signaling. We found that most of the research has been executed in a controlled environment with a continuous supply of nutrients and water; more field studies should be conducted to assess the behavior of related/ non-related conspecifics. Furthermore, not many studies have focused on kin related plant communication via volatile signals, protein interaction and cues.
