桦木（Betula pendula）是研究多年生木本植物季节反应的优秀模型，基因组技术的快速发展使其变得可行。本文强调，在基因组水平上研究树木不仅可以回答木材形成的问题，而且有助于揭示越冬多年生植物生长季节控制背后的机制。它提供了对植物在生理水平上反应的遗传调控的更深入的了解，不仅可以利用其基因进行更快的树木育种，而且还可以作为分子标记和转基因方法。基因的表达序列标签测序、聚类和注释为此类分析提供了基本工具，并通过“电子北方”和微阵列进行表达分析。这些信息与候选基因的功能分析一起，有助于阐明树木的基本过程，并将有助于促进生长特性改善的树木的育种。
Birch (Betula pendula) is an excellent model in studying seasonal responses of woody perennials, made feasible by the rapid development of genomic techniques. This paper emphasizes that studying trees at the genomic level may thus not only give answers to topics in wood formation, but also help to unravel mechanisms behind the seasonal control of growth in overwintering perennials in general. It provides a deeper understanding of genetic regulation of plant responses at the physiological level, not only for the utilization of its genes for faster tree breeding, but also as both molecular markers and in transgenic approaches. Expressed sequence tags sequencing, clustering and annotation of genes provide the basic tools for such analysis aided by expression analysis through 'electronic northerns' and microarrays. This information, together with functional analysis of candidate genes, has helped elucidate basic processes in trees and will help to facilitate breeding of trees with improved growth characteristics.
