The Erdos-Sos conjecture says that a graph G on n vertices and number of edges e（G）〉 n（k - 1）/2 contains all trees of size k. In this paper we prove a sufficient condition for a graph to contain every tree of size k formulated in terms of the minimum edge degree ξ（G） of a graph G defined as {（G） = min{d（u）＋ d（v） - 2 ： uv ∈ E（G）}. More precisely, we show that a connected graph G with maximum degree △（G） ≥ k and minimum edge degree {（G）〉 2k - 4 contains every tree of k edges if dG（x）＋ dG（y） ≥ 2k - 4 for all pairs x, y of nonadjacent neighbors of a vertex u of dG（u） ≥ k.

The clustered regularly interspaced short palindromic repeat(CRISPR)-associated protein 9(Cas9)genome editing system is a powerful tool for targeted gene modifications in a wide range of species,including plants. Over the last few years, this system has revolutionized the way scientists perform genetic studies and crop breeding, due to its simplicity, flexibility, consistency and high efficiency. Considerable progress has been made in optimizing CRISPR/Cas9 systems in plants, particularly for targeted gene mutagenesis. However, there are still a number of important challenges ahead, including methods for the efficient delivery of CRISPR and other editing tools to most plants, and more effective strategies for sequence knock-ins and replacements. We provide our viewpoint on the goals, potential concerns and future challenges for the development and application of plant genome editing tools.
