[Abstract]  The outward growths from one or more epidermal cells are well known as trichomes (plant hair cells) (Levin, 1973; Mathur, 2006). Preparation of pure intact non-glandular trichomes from trichome-rich Brassica villosa depended on rendering the trichomes sufficiently stiff to dislodge them from the leaves in an undamaged state, which can be further used for structural, transcriptome, genome and biochemical or chemical analysis. Dislodging the flexible trichomes from Brassica villosa (B. villosa) with a paintbrush [as in Zhang and Oppenheimer (2004)] proved too gentle, ... [摘要]  来自一种或多种表皮细胞的向外生长是众所周知的毛状体(植物毛细胞)(Levin,1973; Mathur,2006)。从富含毛藓的芸苔制备纯的完整无腺毛状体依赖于使毛状体足够坚硬,以便在未受损的状态下将它们从叶子上除去,这可以进一步用于结构,转录组,基因组和生化或化学分析。用油漆刷(如Zhang和Oppenheimer(2004)中所述)从芸苔属villosa( B。villosa )中移出柔性毛状体证明太柔和,剃刀刀片[如Zhang和Oppenheimer(2004)]导致毛状体细胞破裂。 Aziz等人(2005)报道了通过在液氮中剪切来分离苜蓿腺毛状体(N 2 sub)。在本研究中,使用类似的方法。通过用液体N 2处理组织以硬化柔性毛状体,接着用共同的涡旋混合器剪切1分钟的剪切力以从其叶床上除去毛状体来分离非腺体叶毛状体(Nayidu et al。 em> et al。,2014)。高达〜20%的毛状体从叶表面除去,并且大多数未破裂(通过台盼蓝没有染色证实;图1)。然后通过使组织/毛/水混合物通过筛子来纯化毛状体。然而,如果将叶组织搅拌较长时间,则在浸入液体N 2后叶组织也变得非常脆,并且分裂成非常小的碎片。因此,N ...
