Changes in plastid biogenesis leading to the formation of albino regenerants in barley microspore culture.

ABSTRACT:

Background

Microspore embryogenesis is potentially the most effective method of obtaining doubled haploids (DH) which are utilized in breeding programs to accelerate production of new cultivars. However, the regeneration of albino plants significantly limits the exploitation of androgenesis for DH production in cereals. Despite many efforts, the precise mechanisms leading to development of albino regenerants have not yet been elucidated. The objective of this study was to reveal the genotype-dependent molecular differences in chloroplast differentiation that lead to the formation of green and albino regenerants in microspore culture of barley.

Results

We performed a detailed analysis of plastid differentiation at successive stages of androgenesis in two barley cultivars, 'Je
