Expression of FLOWERING LOCUS C differentiates summer and winter biotypes of Camelina sativa (Plant Direct)
Plant Science Research WeeklyCamelina sativa is a member of the Brassicaceae family that is grown as an oilseed crop. It has summer and winter flowering biotypes, the latter of which requires vernalization to induce flowering. These two biotypes allow for double-cropping, and the winter-flowering biotype can also be used as a…
Rice Panicle Morphogenesis: Intercommunication Between Grain Number and Size
Research, The Plant Cell, The Plant Cell: In a NutshellGuo et al. investigate the trade-off between seed number and seed size of rice. Plant Cell (2018) https://doi.org/10.1105/tpc.17.00959.

Background: Rice is one of the main staple cereal crops…
miRNA-Mediated Regulation of Germination
Research, The Plant Cell, The Plant Cell: In a NutshellGuo et al. show that miR9678 affects seed germination in wheat by generating phased siRNAs and modulating abscisic acid/gibberellin signaling. Plant Cell https://doi.org/10.1105/tpc.17.00842
By Guanghui Guo and Yingyin Yao
Background: Seed germination is important for grain yield and quality…
Gender Identity in Kiwifruit
Research, The Plant Cell, The Plant Cell: In a NutshellAkagi et al. identify a gender determining gene in kiwifruit. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00787
By T. Akagi, I. M. Henry, H. Ohtani, T. Morimoto, K. Beppu, I. Kataoka, and R. Tao
Background: In flowering plants, hermaphroditism, or the presence of both male and female…
Feedback regulation of COOLAIR expression controls seed dormancy and flowering time ($)
Plant Science Research WeeklyFLOWERING LOCUS C (FLC) and FLOWERING LOCUS T (FT) are proteins required for seasonal sensing in plants. Specifically, FLC and FT control seed dormancy and flowering time. In the control of flowering time, FLC expression is regulated by the prolonged-cold induction of antisense transcripts at FLC known…
PLANT PROTEIN MEETS HOMER´S TROJAN HORSE
Research, The Plant Cell, The Plant Cell: In a NutshellBy Karina van der Linde and Virginia Walbot
Background: In contrast to animals in which meiotically competent cells develop in embryos, plants switch from vegetative to reproductive growth only during flowering. In maize, the most productive cereal crop, the tassel contains male flowers in which…
Open Access Shy Girl Gives Kiwifruit Male Flowers
Blog, Research, The Plant Cell, The Plant Cell: In BriefFrom the human perspective, separate sexes are the norm while hermaphroditism is an exotic concept. For plants, hermaphroditism is the norm. Dioecy, separate male and female individuals, is rare and dispersed in the angiosperm phylogeny (Käfer et al 2017, Renner 2014). In fact, dioecy is rare enough…
The ADAPTOR PROTEIN-3 complex mediates pollen tube growth by coordinating vacuolar targeting and organization (Plant Physiol)
Plant Science Research WeeklyAdaptor proteins (AP) are involved in sorting proteins and are able to recognize cargo and coat proteins during vesicle formation. AP-3 specifically targets protein cargoes to vacuoles. Feng et al. investigate the role of AP-3 in plant reproduction. ap-3 mutants have reduced seed set that is characterized…
