Plant cells are under constant turgor pressure that pushes the plasma membrane tightly against the cell wall. Under severe water loss, cells shrink and membrane retracts without fully detaching from the wall. Narrow bands known as Hechtian strands remain tethered to the cell wall at membrane/wall contact sites. However, the identity and physiological role of […]
Waterlogged paddy soils create anaerobic environments that support the growth of methanogenic archaea, contributing 7-17% of global methane (CH4) emissions. Prior work has shown that rice varieties with more extensive root aerenchyma can better oxygenate the surrounding soil, thereby reducing CH4 emissions. Additionally, peptides such as PLANT PEPTIDES CONTAINING SULFATED TYROSINE (PSY) have been shown […]
In plants, plasmodesmata provide essential symplastic connections for the movement of nutrients and signals. While their role in developing roots is well established, whether they contribute significantly to radial nutrient transport once roots are fully differentiated is still poorly understood. To address this, Jacquier et al. used tracer dyes and cell-type-specific fluorescent reporters to study […]
