OsHAC1;1 and OsHAC1;2 function as arsenate reductases and regulate arsenic accumulation [PDF]

open access: yes, 2016
Rice is a major dietary source of the toxic metalloid arsenic (As). Reducing its accumulation in rice (Oryza sativa) grain is of critical importance to food safety. Rice roots take up arsenate and arsenite depending on the prevailing soil conditions. The

Anatomy of the root of eight species of emergent aquatic macrophytes from the upper Paraná river, Paraná State, Brazil floodplain - doi: 10.4025/actascibiolsci.v32i3.5509

open access: yesActa Scientiarum: Biological Sciences, 2010
The upper Paraná River floodplain is characterized by the existence of several aquatic and transitional habitats between the aquatic and terrestrial environment, influencing the presence and distribution of aquatic macrophytes.

Cell structure of epiphytic orchids’ root cortex and exodermis shape fungal colonization

open access: yes, 2023
Abstract Epiphytic orchids unlike terrestrial species possess water storage elements as an adaptation to dry habitats. Two types of structures are present in roots and thus involved in interaction with mycorrhizal fungi that obligately colonize roots.

HKT transporters : state of the art [PDF]

open access: yes, 2013
The increase in soil salinity poses a serious threat to agricultural yields. Under salinity stress, several Na+ transporters play an essential role in Na+ tolerance in plants.

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

open access: yesJournal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

Morpho-anatomical characterization of root in recurrent selection cycles for flood tolerance of maize (Zea mays L.)

open access: yesPlant, Soil and Environment, 2009
Changes in root anatomical structures at successive cycles of selection (cycle 1 to cycle 18, alternating) were observed in the study of maize (Zea mays L. cv. Saracura-BRS 4154) capable to survive and produce in temporarily flooded soils; this cultivars

Knocking-Out OsPDR7 Triggers Up-Regulation of OsZIP9 Expression and Enhances Zinc Accumulation in Rice

open access: yesRice Science, 2023
Zinc (Zn) is an essential trace mineral that is required for plant growth and development. A number of protein transporters, which are involved in Zn uptake, translocation and distribution, are finely regulated to maintain Zn homeostasis in plant.

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...
