Abstract
In this protocol, we describe a simple and efficient method for meiotic chromosome spread preparation in rice pollen mother cells. Meiotic chromosome preparation by spreading itself is an important technique for plant cytogenetics (Higgins et al., 2004; Chelysheva et al., 2012; Wang et al., 2009); furthermore, it is a crucial step for applying other cytogenetic methods including Fluorescence in situ hybridization (FISH) and immunostaining.
Materials and Reagents
- Young panicles containing meiocytes of rice (Oryza sativa ssp japonica cv. Zhonghua 11)
- 70%, 90% and 100% ethanol (Analytical Reagents)
- 60% (v/v) acetic acid (Analytical Reagents)
- Carmine (Sigma-Aldrich, catalog number: C1022-25G )
- Liquid nitrogen
- Vectashield Mounting Medium with DAPI (Vector Laboratories, catalog number: H-1200 )
- Carnoy’s fixative (see Recipes)
- Aceto-carmine (see Recipes)
Equipment
- Stereo microscope
- Fluorescence microscope (Zeiss, model: AX10 )
- Microscopic slides and cover slips
- Dissection needles and fine forceps
- Heating block
- CCD camera (Hamamatsu Photonics K.K., model: ORCA-R2 C10600 )
