霍夫曼說： 「我們觀察到的海狗行為將影響海狗基因的多樣性，這也可能是它們在100年前瀕臨滅絕又重新繁盛的原因。Although the original species becomes extinct, its genes are carried by the new group.
原來的種雖然絕滅了，但其基因則被一個新的門類所繼承。With the acceleration of extinction of species, biodiversity conservation is extensively concerned. the extinction of species is concerned with the degree of threat by biotic and abiotic factors. so, taking action to preserve plant species is very necessary and paramount before their extinction. one of the most effective biological techniques to conserve the biodiversity is the establishment of genebanks, i. e. ex situ conservation. the elucidation of various factors that regulate seed viability and vigor in storage is essential. an ideal condition to prolong the longevity is mainly depended on seed water content, temperature, humidity and types of containers used during storage. the optimum stage of seed maturity, harvesting techniques and processing, in addition to physiological features such as degree of dormancy, also play key roles in seed storage. certainly, desiccated seeds deteriorate with time even under extremely good genebanking conditions. according to seed storage behavior, it is necessary to consider three principal factors : storage environment, storage duration and plant species which will affect seed survival under good genebanking conditions. the present review is an attempt to discuss the importance of the aforementioned aspects of seeds in detail in order to conserve plant germplasms ( especially wild rare and endangered plants ) for ex situ conservation through seed - gene bank
一個物種的滅絕是與其受生物因子和非生物因子的威脅程度相關的.隨著物種的加速絕滅，保護生物多樣性受到廣泛地關注.保護生物多樣性的最有效的生物技術之一是建立種子基因庫，進行遷地保護.種子庫理想的貯藏條件主要取決于種子含水量、貯藏環境（如溫度和濕度）和貯存種子的容器.進行種子貯藏，了解種子生命力和活力的影響因子的作用機理是十分重要和必要的.除了種子自身的生理特徵外，種子的貯藏壽命與種子成熟度、收獲技術、加工處理方法也是息息相關的.即使在最適的庫存條件下，種子也會隨時間發生劣變.因此，必須根據種子特定的貯藏行為，加以考慮影響種子存活的3個主要方面（貯藏環境、貯藏期和植物種類）而選擇有效的貯藏方案.本文試圖討論種子貯藏生理的幾個重要方面及其需解決的技術問題，以便更好地通過種子基因庫，長期有效地保存植物種質資源Until now many researchers have argued that it would be impossible to sequence the entire genome of an extinct creature because the samples are so degraded
到目前為止，許多研究人員爭論說對一種已經滅絕的物種進行全基因組測序是不可能的，因為那些標本退化嚴重。It is necessary for a species " adaptation and evolutionary potential to keep genetic variety at a relative level. genetic diversity in the population must not be lost furthermore and gene exchange among individuals should be enhanced as much as possible to avoid extinction of crested ibis
一定程度的遺傳變異性是維持種群的適應力與進化潛力的必要條件，為使朱?免於滅絕的厄運，必須避免其種群遺傳多樣性的進一步喪失，並盡可能增加個體間的基因交流，最大限度地避免近親繁殖。Two - toned birds in general don ' t go completely extinct, because as soon as one species vanishes from a neighborhood, other colorful ones take its place
基本上，公、母鳥羽色不同的鳥種並不會完全滅絕，因為某地區的鳥兒一旦消失，即刻會有其他的同種鳥兒從鄰近地方補充進來。Organizers say the effort will secure more than ninety five percent of in dangerthe endangered crops diversity represented in gene banks in developing countries
組織者稱此項努力能夠拯救95 %以上瀕臨滅絕的農作物，它們代表了發展中國家基因庫中的主要農作物。Tracking the evolutionary path of genes and pseudogenes helps molecular biologists to uncover instances of gene birth and death just as the study of mineral fossils tells paleontologists about the creation and extinction of species
追蹤基因和偽基因的演化路徑，讓分子生物學家得以了解基因的出生和死亡，就像古生物學家利用化石來推斷物種的誕生和滅絕一樣。分享友人
