- Abstract
A simple and rapid method for cloning specific cDNAs from mRNA populations derived solely from small numbers of root‐hair cells is described here. To identify genes expressed during the earliest visible stage of root‐hair cell development, cell contents were aspirated from small numbers of Arabidopsis root‐hair cells at or just before this stage. This material was used to make reusable solid‐phase oligo‐dT‐primed cDNA libraries. To demonstrate that the libraries contained high quality longer cDNAs, a fragment located 2.7 kb from the 3′ end of the cDNA of the single copy root‐hair expressed gene RHD3 was cloned using a nested PCR strategy. This technique was also used to obtain novel gene expression information by cloning the full‐length 0.85 kb cDNA of the Rop2 GTPase from this library. This approach offers a means of cloning larger cDNAs directly from small numbers of growing root‐hair cells and, potentially, other epidermal cell types.
