The spikelet, a different “flower” in rice

Descriptive paragraph. Plant Cell https://doi.org/10.1105/tpc.18.00682 By Hui Zhuang and Yunfeng Li Background: The spikelet, often mistaken for a “flower”, is actually an inflorescence unit and can produce one or more florets in some species of grass. This implies that it could be possible…

Fine control of aerenchyma and lateral root development through Aux/IAA- and ARF-dependent auxin signaling ($) (PNAS)

Auxin plays a major role in plant development and can alter the developmental program following the stress response. In this paper, Yamauchi et al., have identified the auxin signaling cascade involved in the development of aerenchyma and regulators of this auxin signaling might also be involved in lateral…

A Transcription Factor, OsMADS57, Regulates Long-Distance Nitrate Transport and Root Elongation (Plant Phys.)

Nitrogen is a critical macronutrient for plant growth and reproduction, and it’s largely present as ammonium in flooded and acidic soils. However, structurally porous tissue in rice roots, called aerenchyma, transfer oxygen to the root system in flooded paddies, increasing nitrate abundance. Huang…
