Definitions
- the present invention relates to a callus inducer and a callus induction method.
- Plants have totipotency, can form callus from highly differentiated somatic cells, and if cultured under certain conditions, callus can undergo plant differentiation through somatic embryos, adventitious buds and adventitious root differentiation. Can be played.
- the callus culture is 1) has infinite growth ability, 2) can be differentiated from a cell mass of callus into various tissues and individuals, 3) uniform and large number of proliferating cells that are difficult to obtain in plants 4) It is suitable as an experimental material with no seasonal variation in cell quality and quantity. 5)
- the effects of substances added to the medium can be directly seen on the plant. It is excellent in that it is easily induced and can be used for breeding. Therefore, callus culture is widely used for production of useful substances, development of new varieties, gene transfer into plant bodies and regeneration of transformants, production of artificial seeds, and the like.
- Non-patent Document 1 Callus is usually produced by a method of culturing a plant tissue section on a medium containing plant hormones auxin and cytokinin. This method has been established over 30 years ago and is now an indispensable technique for the production of genetically modified crops. On the other hand, since the types and concentration ratios of auxin and cytokinin used differ depending on the plant species, it has been difficult to find appropriate callus formation conditions.

It has been reported that the days required for callus formation, adventitious shoots and adventitious root formation were shortened by specific concentration treatment (Non-patent Document 2). However, it cannot be said that the efficiency of callusification is high, and plant species that can be callusified are limited.

(1)フィペキシド処理によるアラビドプシス(Columbia)の形態観察
フィペキシドを0、15、30又は45μM添加した1/2MS培地にアラビドプシス(Columbia)の野生型種子を播種し、形態観察を行った。
アラビドプシス(Columbia)の根器官を切断後、フィペキシドを45μM添加した1/2MS培地中で2週間処理してカルスを誘導させた後、再分化培地(オーキシン/サイトカイニン)中で培養したところ、再分化が認められた(図2A)。
アラビドプシスにおけるカルス誘導において、最適化されたオーキシン/サイトカイニン濃度条件下(2,4-ジクロロフェノキシ酢酸2.26μM/カイネチン0.465μM)でのカルス誘導と、フィペキシド45μMによるカルス誘導を比較したところ、フィペキシドは、最適化されたオーキシン/サイトカイニン濃度条件下でのカルス誘導効率よりも、高頻度でカルス誘導を引き起こすことがわかった。恒常的光照射条件において、87日間培養した胚軸の状態を図3に示す。
フィペキシドは4-クロロフェノキシ酢酸と1-ピペロニルピペラジンがアミド結合した化合物であり、植物体中で非酵素的に加水分解されることが予想された。そこで4-クロロフェノキシ酢酸と1-ピペロニルピペラジンによる単剤処理又は併用処理を試みた。
アラビドプシス発芽条件と同様に、滅菌種子を用いた条件において、フィペキシド培地で培養した結果、イネ発芽種子、ユーカリ発芽種子、ダイズ種子(鶴の子)、トマト種子(マイクロトム)、キュウリ種子(夏すずみ)において、カルス誘導を認めた。
ポプラにおける通常のカルス化誘導条件で、オーキシン/サイトカイニンに換えて、フィペキシドを用いて、カルス誘導を行って、アグロバクテリウムを感染させたカルスが形質転換されているかを確認した。
1.ポット内で育てた無菌培養ポプラ(Populus tremula x tremuloides T89)幼個体から、茎サンプル(5mm長)を切り出した。
2.アグロバクテリウムと共培養した(3日間、暗所、22℃)。
3.アグロバクテリウムを洗浄後、MS1培地あるいは改変MS1培地(3-インドール酪酸(IBA)と6-ベンジルアミノプリン(BAP)の代わりに30μMフィペキシドを含む)の上に置床し25℃で培養した。
4.(4週間目、通常MS1培地ではカルスができていないのに対してフィペキシドを含む改変MS1培地ではカルスが旺盛にできていることを確認した。)
5.カルス誘導培養2ヶ月後のカルス23個体を90%(w/w)アセトンにて-30℃一晩固定の後、サンプルを50mM PBSバッファー(pH7.0)で2回洗浄後、GUS基質液中、37℃で15分インキュベートして染色した。
