Summary The effect of different durations waterlogging and subsequent drainage is described for 3‐wk‐old wheat ( Triticum aestivum ) plants. In a pot experiment, plants were subjected to the soil surface 0, 3, 7, 14, 21 or 28 d, then drained allow recovery up 25 d. During waterlogging, seminal root system stopped growing. Adventitious roots grew maximum length c . 150 mm. Leaf nitrogen concentration was severely decreased by waterlogging. When waterlogged pots drained, mass did not recover...
Enhancement of oxygen transport from shoot to root tip by the formation aerenchyma and also a barrier radial loss (ROL) in roots is common waterlogging-tolerant plants. Zea nicaraguensis (teosinte), wild relative maize (Zea mays ssp. mays), grows waterlogged soils. We investigated ROL induction Z. nicaraguensis, comparison with (inbred line Mi29), pot soil system hydroponics. Furthermore, depositions suberin exodermis/hypodermis lignin epidermis adventitious grown aerated or stagnant...
Aggressive antisocial behaviours are the most common reasons why adolescents referred to mental health clinics. Antisocial costly in social and financial terms. The aetiology of aggressive is unknown but growing evidence suggests it heritable, certain genetic variants have been implicated as contributing factors. purpose this study was determine whether genes regulating hormone oxytocin (OXT) were associated with behaviour. case‐control sample consisted 160 cases children displaying extreme,...
In Asia, cassava (Manihot esculenta) is cultivated by more than 8 million farmers, driving the rural economy of many countries. The International Center for Tropical Agriculture (CIAT), in partnership with national agricultural research institutes (NARIs), instigated breeding and agronomic 1983. program has successfully released high-yielding cultivars resulting an average yield increase from 13.0 t ha–1 1996 to 21.3 2016, significant economic benefits. Following success increasing yields,...
Internal aeration is crucial for root growth in waterlogged soil. A barrier to radial oxygen loss (ROL) can enhance long-distance transport via the aerenchyma tip; a higher concentration at apex enables into anoxic The ROL formed within outer part of roots (OPR). Suberin and/or lignin deposited cell walls are thought contribute barrier, but it unclear which compound main constituent. This study describes gene expression profiles during formation rice determine relative responses suberin...
The growth reduction of wheat (Triticum aestivum L.) during and after waterlogging stress depends on the depth water from soil surface. In a pot experiment with 3-week-old plants, was waterlogged for 14 d at surface, or 100 200 mm below pots were then drained to assess recovery. A fully treatment kept field capacity served as control. During waterlogging, relative rate roots decreased more than that shoots (by 6–27% shoots, by 15–74% roots), plant reduced proportionally level increased....
Floods impede gas (O2 and CO2 ) exchange between plants the environment. A mechanism to enhance plant under water comprises films on hydrophobic leaves, but genetic regulation of this is unknown. We used a rice mutant (dripping wet leaf 7, drp7) which does not retain its wild-type (Kinmaze), in gene discovery for trait. Gene complementation was tested transgenic lines. Functional properties leaves as related film retention underwater photosynthesis were evaluated. Leaf Gas Film 1 (LGF1)...
Abstract A radial oxygen loss (ROL) barrier in roots of waterlogging‐tolerant plants promotes movement via aerenchyma to the root tip, and impedes soil phytotoxin entry. The molecular mechanism genetic regulation ROL formation are largely unknown. Zea nicaraguensis , a wild relative maize ( mays ssp. ), forms tight its when waterlogged. We used Z . chromosome segment introgression lines (ILs) (inbred line Mi29) elucidate chromosomal region involved regulating formation. short‐arm 3 conferred...
Abstract Waterlogged soils contain monocarboxylic acids produced by anaerobic microorganisms. These “organic acids” can accumulate to phytotoxic levels and promote development of a barrier radial O 2 loss (ROL) in roots some wetland species. Environmental cues triggering root ROL induction, feature that together with tissue gas‐filled porosity facilitates internal aeration, are important elucidate for knowledge plant stress physiology. We tested the hypothesis comparatively low, non‐toxic,...

Waterlogging reduces the yield of food crops. Tolerance to waterlogging could vary between and within species. This study aimed quantify tolerance soil in two divergent genotypes pea (Pisum sativum), lentil (Lens culinaris) a grasspea (Lathyrus sativus) control at germination during vegetative growth. Following germination, seeds were grown for 14 days waterlogged with water table 10 mm below surface, then by draining pots allowing recover 21 days—to be compared 35 continuous waterlogging....
ABSTRACT This study investigated aerenchyma formation and function in adventitious roots of wheat ( Triticum aestivum L.) when only a part the root system was exposed to O 2 deficiency. Two experimental systems were used: (1) plants soil waterlogged at 200 mm below surface; or (2) nutrient solution with apical region single deoxygenated stagnant agar remainder aerated solution. Porosity increased two‐ three‐fold along entire length that grew into water‐saturated zone surface, also aerobic...
Background and AimsWhen root-zone O2 deficiency occurs together with salinity, regulation of shoot ion concentrations is compromised even more than under salinity alone. Tolerance was evaluated amongst 34 accessions Hordeum marinum, a wild species in the Triticeae, to combined deficiency. Interest H. marinum arises from potential use it as donor for abiotic stress tolerance into wheat.
Cassava (Manihot esculenta Crantz) is a rainfed, smallholder-produced crop in mainland Southeast Asia, and currently facing serious challenge posed by the introduction of cassava mosaic disease (CMD). This study assessed susceptibility popular Asian varieties to CMD, yield penalties associated with disease, efficacy selecting clean or asymptomatic plants as seed for following season. Field experiments evaluated agronomic management practices (i.e., fertilizer application, use symptomatic...
