Anatomical features of an African sorghum landrace adapted to flooded conditions [PDF]

open access: yes, 2016
This research aims to evaluate adaptation of two contrasting sorghum genotypes to flooding: a landrace from Cameroon described as a “floating sorghum” (Wulaga) and a typical dryland improved variety (Cirad437) from Burkina Faso.

Cell wall changes during the formation of aerenchyma in sugarcane roots [PDF]

open access: bronzeAnnals of Botany, 2017
Aerenchyma develops in different plant organs and leads to the formation of intercellular spaces that can be used by the plant to transport volatile substances. Little is known about the role of cell walls in this process, although the mechanism of aerenchyma formation is known to involve programmed cell death and some cell wall modifications.

Root and microbial contributions to anoxic microsite formation in the rhizosphere: a microfluidic approach

open access: yesNew Phytologist, EarlyView.
Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...

Corn root morphoanatomy at different development stages and yield under water stress [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2016
: The objective of this work was to characterize the morphoanatomy of roots and the yield traits of two corn hybrids contrasting for drought tolerance (DKB 390, tolerant; and BRS 1030, sensitive), at different stages of development.

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Root cortical aerenchyma inhibits radial nutrient transport in maize (Zea mays) [PDF]

open access: yesAnnals of Botany, 2013
Formation of root cortical aerenchyma (RCA) can be induced by nutrient deficiency. In species adapted to aerobic soil conditions, this response is adaptive by reducing root maintenance requirements, thereby permitting greater soil exploration. One trade-off of RCA formation may be reduced radial transport of nutrients due to reduction in living ...

Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

Plant responses to limited aeration: Advances and future challenges

open access: yesPlant Direct, 2023
Limited aeration that is caused by tissue geometry, diffusion barriers, high elevation, or a flooding event poses major challenges to plants and is often, but not exclusively, associated with low oxygen.

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Iron oxidation on the surface of adventitious roots and its relation to aerenchyma formation in rice genotypes

open access: yesRevista Brasileira de Ciência do Solo, 2014
Establishment of the water layer in an irrigated rice crop leads to consumption of free oxygen in the soil which enters in a chemical reduction process mediated by anaerobic microorganisms, changing the crop environment.
