Pink Petuniahybrida (cv Hit Parade Rosa) corollas were found to contain photosynthetically active chloroplasts. The corolla chloroplasts were similar to those of green leaves in size and structure. The chlorophyll (Chl) content of Petunia corollas increased during early stages of flower development, reaching a maximum just before anthesis. Chloroplasts isolated from corollas at this stage, carr...

Variegation of leaves is found widely distributed in the genera of the plant kingdom. Many forms are of great intrinsic beauty and are therefore a common feature in estates and gardens. The chlorotic areas usually appear as pale edges of varying width and regularity around and overlying an otherwise apparently normal green leaf, but very often whole leafy branches may appear colourless while ot...

Cysteine proteinases are involved in various physiological and developmental processes in plants. Two cDNAs from senescent and non-senescent tobacco leaves were isolated with degenerate primers designed from conserved regions of plant senescence-associated cysteine proteinases using rapid amplification of cDNA ends (RACE). Both sequences encode papain-like cysteine proteinases: the 833 bp fragm...

Bauhinia variegata, "PURPLE ORCHID TREE" Spectacular, deciduous tree w/ light green, 2-lobed leaves & 3-in. purple, orchidlike flowers in late winter/early spring (a few may have white flowers). [11] (H*) Caesalpinia mexicana , "MEXICAN BIRD-OF-PARADISE" Heatloving, small tree or large shrub w/ ferny, blue-green leaves & showy clusters of lemon yellow flowers throughout warm weather; needs good...

conclusions this work gained satisfactory results in developing a nutritionally fortified and palatably accepted papads using purslane leaves. background papads are cereal or legume based preserved products rich in proteins. they are consumed after deep fat frying as a side dish in india. in the present work, the traditional savoury was chosen for value addition with green leafy vegetables i.e....

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 mg...

Plant anthocyanin biosynthesis is well understood, but the regulatory mechanism in purple foliage tea remains unclear. Using isobaric tag for relative and absolute quantification (iTRAQ), 815 differential proteins were identified in the leaves of Zijuan tea, among which 20 were associated with the regulation of anthocyanin metabolism. We found that the abundances of anthocyanin synthesis-relate...

Deficiencies in the amount of chlorophyll in the cotton plant have been reported in relatively few instances. BALLS (1908) made a cross between an upland cotton with light green leaves and a dark green Egyptian cotton. He states that in the Fz generation, plants with light green leaves and plants with dark green leaves appeared in a 3 : 1 ratio. STROMAN and MAHONEY (1925) recovered two chloroph...

The distribution of pink-pigmented facultative methylotrophs (PPFMs) on the leaves of various vegetables was studied. All kinds of vegetable leaves tested gave pink-pigmented colonies on agar plates containing methanol as sole carbon source. The numbers of PPFMs on the leaves, colony-forming units (CFU)/g of fresh leaves, differed among the plants, although they were planted and grown at the sa...
