“…[1][2][3]5 Demonstration of these species' ability to recognize surrounding plants as related vs. nonrelated posed the question, how do plants recognize kin? A study conducted by Biedrzycki et al 3 found that A. thaliana plants exposed to the media which previously contained kin plants grew less lateral roots than plants exposed to the media from stranger plants, indicating that A. thaliana plants can sense and respond to a chemical cue left in the media.…”

“…3,4 Supported by evidence that kin recognition occurs in several plant species, including A. thaliana and that root secretion plays a role in this process, Biedrzycki et al 5 elucidated involvement of several root secretion genes involved in the kin recognition process. As previously mentioned, it was determined that addition of sodium orthovanadate (Na 3 VO 4 ), a root secretion and ABC transporter inhibitor, eliminated the increase in lateral root growth associated with exposure to stranger secretions.…”

“…As previously mentioned, it was determined that addition of sodium orthovanadate (Na 3 VO 4 ), a root secretion and ABC transporter inhibitor, eliminated the increase in lateral root growth associated with exposure to stranger secretions. Therefore, Biedrzycki et al 5 tested four additional ABC transporter inhibitors and found a consistent response in elimination of increased lateral root growth in plants exposed to stranger secretions, further indicating the role of ABC transporters in secretion of the kin recognition signals. Subsequent experiments examining gene expression levels of three ABC transporter genes in plants exposed to own, kin and stranger secretions as well as testing of T-DNA insertion mutants of these genes supported the involvement of ABC transporter in varying levels in kin recognition interactions.…”

IntroductionKin recognition in plants is a phenomenon that has recently gained attention in the ecology and plant biology fields as more evidence for these interactions has accumulated. Dudley and File 1 were the first to demonstrate kin recognition in plants through their experiments with Cakile edentula. In their work, C. edentula plants were grown in pots with strangers (plants that were not related) or with kin (plants grown from seed collected from the same mother). Dudley and File 1 found that plants grown with strangers allocated significantly more root mass as compared with plants grown with kin, indicating that the C. edentula plants could not only sense the relatedness of their pot neighbors, but also alter their growth according to the relatedness. In another study with Impatiens pallida, it was found that plants grown with strangers increased allocation in stems and leaves vs. when grown in the presence of kin.2 This study established that another plant species has the ability to alter growth in response to the identity of neighbors, although the response differs between species.Motivated by these studies Biedrzycki et al. 3 examined whether similar kin recognition existed in the model species Arabidopsis thaliana as well whether a root derived chemical may be involved in this response. This study differed from the previously mentioned reports in that plants were grown in liquid growth media in tissue culture plates rather than soil and pots and plants were exposed only to the media that contained secretions (secondary metabolite compound released by plant roots recent reports have demonstrated that Arabidopsis thaliana has the ability to alter its growth differentially when grown in the presence of secretions from other A. thaliana plants that are kin or strangers; however, little knowledge has been gained as to the physiological processes involved in these plant-plant interactions. Therefore, we examined the root transcriptome of A. thaliana plants exposed to stranger vs. kin secretions to determine genes involved in these processes. We conducted a whole transcriptome analysis on root tissues and categorized genes with significant changes in expression. Genes from four categories of interest based on significant changes in expression were identified as aTP/GST transporter, auxin/auxin related, secondary metabolite and pathogen response genes. Multiple genes in each category were tested and results indicated that pathogen response genes were involved in the kin recognition response. Plants were then infected with Pseudomonas syringe pv. Tomato Dc3000 to further examine the role of these genes in plants exposed to own, kin and stranger secretions in pathogen resistance. This study concluded that multiple physiological pathways are involved in the kin recognition. The possible implication of this study opens up a new dialog in terms of how plant-plant interactions change under a biotic stress.

Does a plant detect its neighbor if it is kin or stranger? Evidence from a common garden experiment

Unlike vagile organisms, plants perform a wide range of phenotypic responses to cope with environmental stresses. A special case of interaction with external factors is the ability of plants to recognize genetic relatedness of neighbour plants, a�t�all� �ell k�� a� ki� �e��iti��. T�e ��e�e�t ��k ai�e� t� ��vi�e a val�able ��t�ib�ti�� t� t�e �el� �� ki� �e��i-tion in plants through a common garden experiment. To avoid bias involved in pot experiments, we perform an experiment in unconstrained root growth conditions comparing the development of coupled kin, non-kin and solitary plants of Xanthium italicum. Biometrics of plants with different genetic relatedness were measured, then architecture and competitive interaction were assessed using the relative interaction index (RII) for above and belowground portions of plants. X. italicum showed different allocation depending on the neighbourhood. Root biomass was declined in plants growing with kin compared to non-kin coupled plants, while plants coupled with kin allocated more shoot than roots compared to solitary plants. RII explains phenotypic response of decreased competition in roots rather than in shoots. Despite high values of RII for the aboveground portion, the architectural analysis of shoot, number, angle and length of branches and roots reveals dramatic but indistinctive change in the �t��t��e �� la�t� ��i�� ea� ki� �� ki� ��a�e� t� a ��lita�� la�t.
