Nitrate transporter NPF7.9 is a regulator nitrogen use efficiency and stress-induced nitrate allocation to roots in rice (Plant Physiol)
In addition to its role as a nutrient and a developmental signal, nitrate regulates stress responses in plants. By homology to nitrate transporters previously identified in Arabidopsis as contributing to stress induced-nitrate allocation to roots (SINAR) and nitrogen use efficiency (NUE), Guan et al.…

OsMADS14 and NF-YB1 cooperate in the direct activation of OsAGPL2 and Waxy during starch synthesis in rice endosperm (New Phytol.)
Rice grain is mainly composed of starch, which provides the necessary energy and sugars for successful germination and seedling development. Since rice is the most widely consumed crop, studying the regulators that control starch synthesis is crucial to ensure food security for more than half the world‘s…
Linking low energy sensing to chromatin modification and gene activity in rice
Wang and colleagues investigated the starvation response of rice seedlings.
By Wentao Wang and Yue Lu
Background: For survival and growth, cells of all living organisms must balance their energy consumption and supply. Although energetically autonomous (through photosynthesis), plants are continuously…
Proteomics-based protein complex discovery in the developing rice aleurone-subaleurone
Lee et al. use a co-fractionation mass spectrometry pipeline to predict the compositions of cytosolic protein complexes present during early rice seed development. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab182
Background: Many proteins act as components of multiprotein complexes that…
Communication between the AGO protein MEL1 and ubiquitination during sporogenesis
Lian et al. investigated the molecular mechanism of AGO protein MEL1 degradation mediated by a new monocot-specific E3 ligase, XBOS36.

Natural Allelic Variation Improves Nitrogen Use Efficiency in Rice
Zhang, Zhu, Shen, Ji et al. discover a way to enhance nitrogen use efficiency and grain yield in rice. The Plant Cell (2020) https://bit.ly/3s3bLb3
Background: Nitrogen (N), an essential element for crop growth, is provided to plants by external fertilizer application. However, the excessive use…
