“…Most of the clones showed significant sequence similarities to the genes previously identified as stress-responsive genes and senescence-related genes from other plant species. [36][37][38] RT-PCR confirmed increased expression of seven genes selected from the identified clones during manufacture (Fig. 3).…”

“…According to Nandi et al (1995), the extent of amylase activity determines germination ability. However, the course of processes involved in the seed germination and metabolism of the compounds mentioned above can be affected by a number of environmental factors such as irradiance, temperature, salinity, drought, and type of ions present (Bohnert et al, 1995).…”

A b s t r a c t. The aim of this study was to determine the effect of pre-sowing helium-neon (He-Ne) laser irradiation of pea seeds on changes in seed biochemical processes, germination rate, seedling emergence, growth rate, and yield. The first experimental factor was exposure to laser radiation: D0 -no irradiation, D3 -three exposures, D5 -five exposures, and the harvest dates were the second factor. Pre-sowing treatment of pea seeds with He-Ne laser light increased the concentrations of amylolytic enzymes and the content of indole-3-acetic acid (IAA) in pea seeds and seedlings. The exposure of seeds to He-Ne laser light improved the germination rate and uniformity and modified growth stages, which caused acceleration of flowering and ripening of pea plants. Laser light stimulation improved the morphological characteristics of plants by increasing plant height and leaf surface area. Irradiation improved the yield of vegetative and reproductive organs of pea, although the effects varied at the different growth stages. The increase in the seed yield resulted from a higher number of pods and seeds per plant, whereas no significant changes were observed in the number of seeds per pod. Both radiation doses exerted similarly stimulating effects on pea growth, development, and yield.

“…Osmotic stress results in morphological and biochemical changes that lead to the rapid cessation of nitrogen fixation (Pankhurst and Sprent, 1975;Weisz et al, 1985;Serraj et al, 1994), the induction of genes involved in stress adaptation (Delauney and Verma, 1990), and the accumulation of compatible solutes such as Pro and sugars, presumably to restrict water loss (Kohl et al, 1991;Irigoyen et al, 1992). Changes in membrane permeability coordinated with the accumulation and compartmentation of compatible solutes may be part of the osmotic adjustment, aiding in the maintenance of cell turgor and redirecting tissue water flow toward critical cells (Bohnert et al, 1995). Thus, the increase in the phosphorylation of nodulin 26 in response to salinity may represent part of a larger adaptation response of nodules to osmotic stress.…”

Phosphorylation of Soybean Nodulin 26 on Serine 262 Enhances Water Permeability and Is Regulated Developmentally and by Osmotic Signals

Soybean nodulin 26 is expressed and targeted to the symbiosome membrane of nitrogen-fixing nodules, where it forms an aquaporin channel with a modest water transport rate. In this study, we show that the phosphorylation of nodulin 26 on Ser-262, which is catalyzed by a symbiosome membrane-associated calcium-dependent protein kinase, stimulates its intrinsic water transport rate. Furthermore, using a phosphospecific antibody, we have elucidated the developmental appearance and regulation of nodulin 26 phosphorylation in vivo. Although nodulin 26 protein is detected first in differentiating infected cells (16 days), phosphorylated nodulin 26 does not become pronounced until infected cell maturation (25 days). Phosphorylation is sustained at steady state levels until entry into senescence. Nodulin 26 phosphorylation is enhanced further by osmotic stresses (water deprivation and salinity). Thus, the phosphorylation of nodulin 26 coincides with the establishment of mature nitrogen-fixing symbiosomes, is regulated by osmotic stresses that induce calcium-signaling pathways, and appears to be part of the adaptive responses of infected cells to osmotic challenge.
