Abstract
Plant secondary cell wall provides physical support for upright growth and transportation of water and nutrients. Detailed characterization of the molecular mechanism for SCW biosynthesis would be of great importance for breeding maize varieties. Cellulose, synthesized by the cellulose synthase complex (CSC), composed of cellulose synthase (CesA) proteins, is a main component of plant cell walls. However, CesA genes that are specific for SCW biosynthesis in maize were undefined. In our study, ZmCesA10, 11, and 12 were characterized to be responsible for SCW biosynthesis in maize. ZmCesA10, 11, and 12 interact with each other and are co-expressed in maize culms and roots. Mutants for ZmCesA10, 11, and 12, exhibited an increased culm brittleness, a reduced cell wall thickness, and cellulose content. We concluded that ZmCesA10, 11, and 12 would be markers for the SCW study, and finally this study helps in the construction of the molecular network for SCW biosynthesis in maize.
期刊介绍：
Journal of Plant Biology, an official publication of the Botanical Society of Korea, is an international journal devoted to basic researches in biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants.
The Journal publishes the following categories of paper:
Original articles -- For publication in Journal of Plant Biology the manuscript must provide a significant new contribution to our understanding of plants. All areas of plant biology are welcome. No limit on the length, but a concise presentation is encouraged.
Reviews -- Invited by the EiC.
Brief Communications -- Concise but independent report representing significant contribution to plant science.
The Botanical Society of Korea was founded on November 30, 1957 to promote studies, disseminate and exchange information on the field of plant biology. The first issue of The Korean Journal of Botany, the official publication of the society, was published on April 1, 1958. It was published twice a year, but quarterly from 5th volume in 1962. In 1994, it was renamed to Journal of Plant Biology and published in English since 1996. The journal entered its 50th year of publication in 2007.
