FAR-RED ELONGATED HYPOCOTYLS3 (FHY3) and its homolog FAR-RED IMPAIRED RESPONSE1 (FAR1), which play pivotal roles in plant growth and development, are essential for the photo-induced phyA nuclear accumulation and subsequent photoreaction. The FAR1/FHY3 family has been systematically characterized in some plants, but not in . In this study, genome-wide identification of genes in was performed using bioinformatic methods. The gene structures, chromosomal locations, the encoded protein characteristics, 3D models, phylogenetic relationships, and promoter -elements were analyzed with this gene family. A total of 33 genes were identified in , which were divided into three groups based on their phylogenetic relationships. A total of 21 pairs of duplicated repeats were identified by homology analysis. Gene expression analysis showed that most genes were differentially expressed in a spatial-specific manner. Gene expression analysis also showed that genes responded to salt and temperature stresses. These results and observation will enhance our understanding of the evolution and function of the genes in and facilitate further studies on the molecular mechanism of the gene family in growth and development regulations, especially in response to salt and temperature.
远红光伸长下胚轴3（FHY3）及其同源物远红光反应受损1（FAR1）在植物生长发育中起关键作用，对光诱导的phyA核积累及随后的光反应至关重要。FAR1/FHY3家族已在一些植物中得到系统表征，但在[具体植物名称未给出]中尚未有此研究。在本研究中，利用生物信息学方法对[具体植物名称未给出]中的[该家族]基因进行了全基因组鉴定。对该基因家族分析了基因结构、染色体定位、编码蛋白特性、三维模型、系统发育关系及启动子元件。在[具体植物名称未给出]中总共鉴定出33个[该家族]基因，根据其系统发育关系分为三组。通过同源性分析共鉴定出21对重复序列。基因表达分析表明，大多数[该家族]基因以空间特异性方式差异表达。基因表达分析还表明，[该家族]基因对盐和温度胁迫有响应。这些结果和观察将增进我们对[具体植物名称未给出]中[该家族]基因进化和功能的理解，并有助于进一步研究该基因家族在生长发育调控尤其是对盐和温度响应中的分子机制。
