Allium fistulosum Genome sequencing. Allium fistulosum

We sampled sequences from the entire genome of multiple species of monocotyledonous plants to explore evolutionary relationships among lineages. Monocots (including such groups as grasses, sedges, palms, gingers, bananas, orchids, onions, yams, pondweeds, and philodendrons) comprise more than 65,000 species of flowering plants, occur in almost all habitats on Earth, and provide the basis for the great majority of the human diet. Monocots also account for much of the commerce in cut flowers and horticultural bulbs such as crocuses, irises, hyacinths, tulips, and lilies. They dominate grasslands, seagrass beds, bamboo thickets, many wetlands, and are especially common on extremely infertile soils. This research will help us understand the context of diversity in monocots.

本研究从多种单子叶植物（monocotyledonous plants）的全基因组中采集序列样本，以探究其各演化谱系间的亲缘演化关系。单子叶植物类群涵盖禾草、莎草、棕榈、姜科、芭蕉、兰科、洋葱、薯蓣、眼子菜、蔓绿绒属等类群，包含超过65000种开花植物，几乎遍布地球所有生境，构成了人类绝大多数膳食的核心基础。单子叶植物同时也是切花与园艺球根花卉（如番红花、鸢尾、风信子、郁金香、百合等）贸易的重要组成部分。它们主导了草原、海草床、竹丛、众多湿地的植被构成，在极端贫瘠的土壤中也极为常见。本研究将助力我们深入理解单子叶植物多样性的演化背景。
