Plant Biotechnology Journal, EarlyView.ABSTRACT Stomata are microscopic pores that regulate the exchange of CO2 and water vapour, making them a major target for engineering plants with improved intrinsic water use efficiency (iWUE). Proof‐of‐concept studies have demonstrated the potential to increase iWUE by reducing stomatal density (SD) and stomatal conductance (gsw) by ubiquitously ...

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

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

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

Plant responses to limited aeration: Advances and future challenges
Plant 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.

Linking Superoxide Production and Scavenging in Plant Development
Plant, Cell &Environment, EarlyView.ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2
Plant, 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.
