The breeding of new, high-quality citrus cultivars depends on dependable information about the relationships of taxa within the tribe Citreae; therefore, it is important to have a well-supported…

Leaf gas films contribute to the submergence tolerance of rice, in addition to those traits already recognized, such as the shoot-elongation response, aerenchyma and metabolic adjustments to O₂ deficiency and oxidative stress.
Soil conditions and cereal root system architecture: review and considerations for linking Darwin and Weaver.
It is found that few controlled-environment studies combine more than one soil stimulus and, those that do, highlight the complexity of responses, and that few field studies report root and soil conditions.
Aquatic adventitious root development in partially and completely submerged wetland plants Cotula coronopifolia and Meionectes brownii.
Submergence tolerance and aquatic root growth and physiology were evaluated in two herbaceous, perennial wetland species Cotula coronopifolia and Meionectes brownii, which responded to submergence with growth of aquatic adventitious roots, which essentially replaced the existing sediment root system.
Photosynthesis in aquatic adventitious roots of the halophytic stem-succulent Tecticornia pergranulata (formerly Halosarcia pergranulata).
The experiments presented here show the aquatic adventitious roots of the flood-tolerant, halophytic stem-succulent, Tecticornia pergranulata are photosynthetically active and quantify for the first time the photosynthetic capacity of aquatic roots for a terrestrial species.

The O2 dynamics of small, shallow vernal pools with dense populations of Isoetes australis were studied in situ, and the potential importance of the achlorophyllous leaf bases to underwater net photosynthesis (PN) and radial O2 loss to sediments is highlighted.
Crassulacean acid metabolism enhances underwater photosynthesis and diminishes photorespiration in the aquatic plant Isoetes australis.

Underwater photosynthesis by aquatic plants is often limited by low availability of CO(2), and photorespiration can be high, so crassulacean acid metabolism in aquatic plants enables higher rates of underwater net photosynthesis over large O(2) and CO(1) concentration ranges in floodwaters, via increased CO( 2) fixation and suppression of photoreSpiration.
Wheats developed for high yield on stored soil moisture have deep vigorous root systems.
An international field selection program is outlined for beneficial root traits at maturity using soil coring in India and Australia for deep rooting traits for wheat selected and bred for high yield under monsoon conditions.
In situ O 2 dynamics in submerged Isoetes australis : varied leaf gas permeability influences underwater photosynthesis and internal O 2

A unique type of vernal pool are those formed on granite outcrops, as the substrate prevents percolation so that water accumulates in depressions when precipitation exceeds evaporation. The O2…
Shoot atmospheric contact is of little importance to aeration of deeper portions of the wetland plant Meionectes brownii; submerged organs mainly acquire O2 from the water column or produce it…

In situ microelectrode studies of the wetland plant Meionectes brownii showed that O(2) dynamics in the submerged stems and aquatic roots of partially submerged plants were similar to those of completely submerged plants, with internal O( 2) concentrations in both organs dropping to less than 5 kPa by dawn regardless of submergence level.
