The transcription of many genes is regulated through alternative splicing, with over 60 percent of genes in Arabidopsis thaliana producing more than one mRNA [1]. The most common forms of alternative splicing are intron retention and the use of alternative polyadenylation sites that result in transcripts…

The Poaceae is one of the largest plant families in angiosperms, containing more than 12,000 grass species, which are classified into two major clades: PACMAD (Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae and Danthonioideae) and BOP (Bambusoideae, Oryzoideae and Pooideae) (Fig.…

For a number of crops agricultural yields have been boosted by the phenomenon of heterosis or hybrid vigour, where a hybrid outperforms either parent. Understanding the various mechanisms by which heterosis arises may facilitate the breeding of hybrids with increased vigour for further crop varieties…

Author: Masanori Izumi Affiliation: Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, Sendai 980–8578, Japan Plants are photoautotrophs that grow via photosynthetic energy production. Under irradiation, chloroplasts in the plant’s green tissues convert light energy…

Jose M Celedon 1 1 Michael Smith Laboratories, The University of British Columbia, 2185 East Mall, Vancouver, BC V6T 1Z4, Canada. Transcriptomic studies in plants usually involve anonymous survey-style methods, where whole organs or tissues are homogenized, and each cell’s contribution to transcript…

Polar localization of plasma membrane proteins is an important way cells regulate signaling pathways, transport across membranes, and growth. Polarization has obvious cellular effects, but localization of membrane components also contributes significantly to processes such as tip growth in root hairs…

The prohibitin (PHB) protein family is highly conserved from prokaryotes to eukaryotes (Van Aken et al., 2010). Initially identified as a tumor suppressor in rat liver, PHBs in animals are localized in various cell compartments, including mitochondria, nuclei, and plasma membranes, and function as scaffold…
