A water-soluble chlorophyll protein in cauliflower may be identical to BnD22, a drought-induced, 22-kilodalton protein in rapeseed.

چکیده
A water-soluble chlorophyll protein (WSCP) in cauliflower (Brassica oleracea L.) was purified and its N-terminal sequence was determined. Forty-six of 48 residues of the sequence completely matched those of the drought-induced 22-kD protein (BnD22) in rapeseed (Brassica napus L.). All 40 sequenced residues of WSCP from rapeseed were perfectly matched to those of BnD22. Thus, WSCP may be identical to BnD22. The abundance of WSCP was increased in detached cauliflower leaves.

A proteomic profiling approach to reveal a novel role of Brassica napus drought 22 kD/water-soluble chlorophyll-binding protein in young leaves during nitrogen remobilization induced by stressful conditions.
Despite its water-soluble chlorophyll-binding protein (WSCP) function, the putative trypsin inhibitor (TI) activity of the Brassica napus drought 22 kD (BnD22) protein and its physiological function in young leaves during leaf nitrogen (N) remobilization promoted by stressful conditions remains an enigma. Therefore, our objectives were to determine (1) if BnD22 is related to the 19-kD TI previo...
متن کاملThe impact of drought stress at different stages of development on water relations, stomatal density and quality changes of rapeseed (Brassica napus L.)
ABSTRACT- To investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including L1 (Field Capacity, FC), L2 (70% Available Water Content, AWC), L3 (50% AWC), and L4 (30% AWC), within three growth stages- including stem elongation (T1), onset of flowering (T2) and silique fo...

In this study the effects of drought stress on proline, protein, chlorophyll a/b, ascorbate and dehrydroascorbate were investigated in Akri and Mobil cultivars of tomato species. The seeds were cultured at 23 °C with 15-16 hours light period and irrigation was done based on field capacity control (FC), mild drought stress (⅔ FC) and severe drought stress (⅓ FC) under greenhouse conditions. Afte...

Drought stress as an abiotic stress causes different biochemical and physiological responses in plants. To study changes in chlorophyll, total soluble protein and antioxidant activity due to drought stress, we conducted an experiment on five durum wheat varieties (selected from the Seed and Plant Improvement Institute in Karaj) at research greenhouse of Imam Khomeini International University in...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...
