Membrane disruption has been proposed to be a key event in plant senescence, and phospholipase D (PLD; EC 3.1.4.4) has been thought to play an important role in membrane deterioration. We recently cloned and biochemically characterized three different PLDs from Arabidopsis. In this study, we

Effect of abscisic acid, gibberellic acid, indoleacetic acid, and kinetin on selective ribosomal cistron regulation in quiescent and senescent onion leaf base tissue.

Small pieces of tissue from the basal, equatorial, near-apical, and apical regions of the third turgid onion leaf base were treated (3 and 6 h in the dark) with abscisic acid (ABA), gibberellic acid (GA3), indoleacetic acid (IAA), and kinetin (K) and compared with responses in water controls. ABA

Alginate oligosaccharide postharvest treatment preserve fruit quality and increase storage life via Abscisic acid signaling in strawberry.

Abscisic acid (ABA) has been advocated to play substantial role on ripening of non-climacteric fruit. Here we report that alginate oligosaccharide (AOS) postharvest treatments delayed the accumulation of ABA and ABA-conjugates and restrained the expression of ABA signaling genes, resulting enlarged

Heat shock factors (HSFs) play crucial roles in various plant stress responses. However, the current knowledge about HSFs in cassava, an important crop, is still insufficient. In this research, we identified 32 cassava HSF genes (MeHSFs) and clustered them into three groups (A, B, C) based on

Cloning and functional analysis of 9-cis-epoxycarotenoid dioxygenase (NCED) genes encoding a key enzyme during abscisic acid biosynthesis from peach and grape fruits.

Ripening and senescence are generally controlled by ethylene in climacteric fruits like peaches, and the ripening process of grape, a non-climacteric fruit, may have some relationship to abscisic acid (ABA) function. In order to better understand the role of ABA in ripening and senescence of these

Abscisic acid-determined seed vigour differences do not influence redox regulation during ageing.

High seed quality is a key trait to achieve successful crop establishment required for optimum yield and sustainable production. Seed storage conditions greatly impact two key seed quality traits; seed viability (ability to germinate and produce normal seedlings) and vigour (germination

The tonoplast intrinsic proteins TIP3;1 and TIP3;2 are specifically expressed during seed maturation and localized to the seed protein storage vacuole membrane. However, the function and physiological roles of TIP3s are still largely unknown. The seed performance of TIP3 knockdown mutants was

Age and sex-related changes in cytokinins, auxins and abscisic acid in a centenarian relict herbaceous perennial.

It is still an unsolved question of fundamental biology if, and how, perennial plants senesce. Here, age- and sex-related changes in phytohormones were tested in Borderea pyrenaica, a small dioecious geophyte relict of the Tertiary with one of the longest lifespan ever recorded for any non-clonal

A rice bZIP protein, designated OSBZ8, is rapidly induced by abscisic acid.

A cDNA that encoded a bZIP protein, designated OSBZ8, was isolated from a rice embryo cDNA library by use of degenerate oligonucleotide probes that corresponded to the amino acid sequences conserved among the basic regions of plant G-box-binding factor-type bZIP proteins (GBF). OSBZ8 was shown to

Quantitative trait loci (QTL) mapping was used to identify loci controlling various aspects of seed longevity during storage and germination. Similar locations for QTLs controlling different traits might be an indication for a common genetic control of such traits. For this analysis we used a new

Perfect timing of germination is required to encounter optimal conditions for plant survival and is the result of a complex interaction between molecular processes, seed characteristics, and environmental cues. To detangle these processes, we made use of natural genetic variation present in an

Quick suberin-based healing after wounding played a protective role for plant to prevent further damage. In this study, the stimulative effect of exogenous abscisic acid (ABA) on wound suberization in postharvest kiwifruit was evaluated through suberin staining with toluidine blue O as well as the

The omics analyses of plants and the agrigenomics field offer the opportunity to better characterize our ecosystems. In this context, characterization of cytochrome P450 genes (CYP450s), which constitute one of the largest gene families in plants, is important. They play vital roles in biosynthesis

The hormonal ratios along the barley spike regulate the development, atrophy and abortion of the spikelets and could be the mechanism by which the barley spike adapts its yield potential. Barley (Hordeum vulgare L.) is one of the oldest cereal crops known to be cultivated since about 10,000 years.

The phytohormone abscisic acid (ABA) is involved in regulating seed dormancy and germination. A crucial step of ABA biosynthesis in higher plants is the oxidative cleavage of cis-epoxycarotenoids by 9-cis-epoxycarotenoid dioxygenase (NCED). Seed development in orchids is unusual because the embryos
