A cDNA clone, corresponding to mRNAs preferentially expressed in the roots of bean (Phaseolus vulgaris L.) seedlings, was isolated. This clone contains a 381 bp open reading frame encoding a polypeptide of 13.5 kDa, designated PVR5 (Phaseolus vulgaris root 5). The amino acid sequence of this clone

Plant cell walls undergo dynamic changes in response to different environmental stress conditions. In response to water deficit, two related proline-rich glycoproteins, called p33 and p36, accumulate in the soluble fraction of the cell walls in Phaseolus vulgaris (Covarrubias et al. in Plant Physiol

There are several mechanisms used by plants for survival in adverse environments such as drought, high temperature and salinity. The objective of this study was to evaluate the drought tolerance of tepary bean as a function of biochemical processes linked to isozyme synthesis and changes in

Excised bean (Phaseolus vulgaris) leaves were used to measure changes in proline content and proline metabolism during rehydration in the dark after the leaves had been incubated in the dark 24 hours in a wilted condition.The increase in nonprotein proline which occurs in wilted leaves stopped

Proline was metabolized when vacuum infiltrated into starved bean (Phaseolus vulgaris L.) leaves from plants previously in the dark for 48 hours, but an equivalent increase in protein proline was not observed. When (14)C-proline was infiltrated into starved leaves, a large percentage of the (14)C

The structure and expression of a cDNA clone (PvPRP1) isolated from a cDNA library prepared from bean (Phaseolus vulgaris) cells treated with fungal elicitor have been characterized. Sequence analysis of the 1.1 kb insert revealed a complete open reading frame which encodes a 32 kDa protein. The

Two antigenically related glycoproteins, called p33 and p36, accumulate in the soluble fraction of the cell wall in response to water deficit in Phaseolus vulgaris. In this report, we show that p33 and p36 are able to adhere to leaf protoplasts, and that they bind to plasma membrane (PM) vesicles in

The interplaying defensive roles of silicon (Si) and proline (Pro) in improving growth and yield attributes, physio-biochemical attributes, and antioxidant defense systems in common bean plant grown under saline (NaCl) and/or cadmium (Cdp>2+p>) stress were assessed. Seed were sown in plastic

We have studied developmental and light regulation of mRNAs encoding a putative cell wall proline-rich protein (PvPRP1), cell wall glycine-rich proteins (GRPs), and cell wall hydroxyproline-rich glycoproteins (HRGPs) in bean (Phaseolus vulgaris). Light increases the levels of these mRNAs 2- to

The effect of water stress on growth (fresh weight, dry weight), water relations (water saturation deficit, water potential, osmotic pressure), and proline metabolism in Phaseolus vulgaris were studied.Experimentally, water deficit was produced by reduced watering of the bean plants. This resulted

17-day-old bean plants (Phaseolus vulgaris cv. Strike) were used to analyze the effects of Co2+ and Zn2+ on the time course of proline, total protein, chlorophyll and abscisic acid (ABA) levels in leaves. Controls, Co2+ and Zn2+-treated plants were grown for 8 days in Hoagland solution. Samples were

The profilin family consists of a group of ubiquitous highly conserved 12-15 kDa eukaryotic proteins that bind actin, phosphoinositides, poly-l-proline (PLP) and proteins with proline-rich motifs. Some proteins with proline-rich motifs form complexes that have been implicated in the dynamics of the

Bean (Phaseolus vulgaris L.) seedlings were subjected to varying selenium levels (1, 2, 4, and 6 ppm) in a hydroponic culture. The germination reached 100% in 48 h in all Se levels except 6 ppm, where it took 72 h. The root and shoot growth was stimulated at 1 and 2 ppm Se levels that was

B-deficient bean (Phaseolus vulgaris L.) nodules examined by light microscopy showed dramatic anatomical changes, mainly in the parenchyma region. Western analysis of total nodule extracts examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that one 116-kD polypeptide was

The isoform composition of the 14.4 kDa profilin polypeptide was analyzed in seeds, leaves, flowers, roots and root-nodules from Phaseolus vulgaris L. Isoforms of pIs approximately 4.4-5 were present in all the tissues analyzed. The biochemical features of the protein present in seed tissue were
