            HAPPY NEW YEAR, PLANT BIOLOGY COMMUNITY! What a year 2019 was! So many wonderful things happened. ASPB hosted another successful Plant Biology meeting in San Jose, CA. We spent the year celebrating The Plant Cell's 30th anniversary (check…

The γ-tubulin complex protein GCP6 in crucial for spindle morphogenesis but not essential for microtubule reorganization in Arabidopsis (OA)

During cell division, cells require to form mitotic spindle and these mitotic spindles are basically newly formed microtubules. The formation of new microtubules depends on γ-tubulin. Along with 5 GPCs (γ-tubulin protein complex), γ-tubulin form γTuRC (γ-tubulin ring complex) and it facilitates…

An Improved Recombineering Toolset for Plants

Brumos and Zhao et al. developed an improved set of genetic tools to make precise sequence modifications in large DNA fragments and used them to tag hundreds of plant genes, including those involved in auxin production. Plant Cell https://doi.org/10.1105/tpc.19.00431 By Javier Brumos, Anna Stepanova,…

Arabidopsis OR Represses the Greening of Cotyledons while It Is in the Nucleus

Sun et al. showed that OR interacts with TCP14 in the nucleus of dark-germinated seedlings and reduces chlorophyll biosynthesis, thylakoid membrane development and expression of EARLY LIGHT-INDUCIBLE PROTEINS, and that subsequent illumination relieves this repression.
