Genome-Wide Identification,Expansion, and Evolution Analysis of Homeobox Gene Family Reveals TALE Genes Important for Secondary Cell Wall Biosynthesis in Moso Bamboo (Phyllostachys edulis)

The TALE gene family is a subfamily of the homeobox gene family and has been implicated in regulating plant secondary growth. However, reports about the evolutionary history and function of the TALE gene family in bamboo are limited. Here, the homeobox gene families of moso bamboo Olyra latifolia and Bonia amplexicaulis were identified and compared. Many duplication events and obvious expansions were found in the TALE family of woody bamboo. PhTALEs were found to have high syntenies with TALE genes in rice. Through gene co-expression analysis and quantitative real-time PCR analysis, the candidate PhTALEs were thought to be involved in regulating secondary cell wall development of moso bamboo during the fast-growing stage. Among these candidate PhTALEs, orthologs of OsKNAT7, OSH15, and SH5 in moso bamboo may regulate xylan synthesis by regulating the expression of IRX-like genes. These results suggested that PhTALEs may participate in the secondary cell wall deposition in internodes during the fast-growing stage of moso bamboo. The expansion of the TALE gene family may be implicated in the increased lignification of woody bamboo when divergent from herbaceous bamboos.

A New Chiral Cu(II) Complex Consisting of Achiral Flexible Tripodal Ligand of Benzene-1,3,5-Triacetate Acid with Phenanthroline

Abstract  

A new chiral Cu(II) complex, Cu₃(phen)₃(H₂O)(BTA)₂·13H₂O (1) (H₃BTA = benzene-1,3,5-triacetate acid and phen = phenanthroline) has been prepared by solvothermal synthesis and structurally characterized by IR, elemental analysis, and single crystal X-ray diffraction. This complex crystallizes in the chiral space group C2 and has similar one-dimensional chains, which are further bridged by μ ₂-H₂O to form a two-dimensional layer structure. The nonlinear optical property and magnetic property were investigated.
