ABSTRACT: An investigation was carried out to estimate the NaCl stress and ameliorative effects of Gibberellic Acid (GA3) on Portulaca grandiflora Hook. A crop experiment was conducted (CRBD) where all the pots were irrigated to field capacity. The treatments were given as (T0) control without NaCl, (T1) 80 mM NaCl, (T2) 80 mM NaCl and 50 ppm GA3, (T3) 80 mM NaCl and 75 ppm GA3 and (T4) 80 mM NaCl and 100 ppm GA3. The samples were collected at 90 DAS. It was found that plants subjected to salt stress generally showed a reduction of vegetative growth. GA3 spraying on Portulaca grandiflora with 75 ppm showed a high amelioration effect on growth and on biochemical patterns, which enhanced salt tolerance. In Portulaca grandiflora, data showed that NaCl stress...

Alterations in core histone variant ratios during maize root differentiation, callus formation and in response to plant hormone treatment
Provedor de dados: Biological Research
Autores: ALATZAS,ANASTASIOS; FOUNDOULI,ATHINA.
Although several histone variants have been studied in both animal and plant organisms, little is known about their distribution during processes that involve alterations in chromatin function, such as differentiation, dedifferentiation and hormone treatment. In this study we evaluated the ratio of each histone variant in each of the four core histone classes in the three developmental zones of maize (Zea mays L.) root and in callus cultures derived from them, in order to define possible alterations either during plant cell differentiation or dedifferentiation. We also evaluated core histone variant ratios in the developmental zones of roots treated with auxin and gibberellin in order to examine the effects of exogenously applied plant hormones to histone...

Distribution of linker histone variants during plant cell differentiation in the developmental zones of the maize root, dedifferentiation in callus culture after auxin treatment
Provedor de dados: Biological Research
Autores: ALATZAS,ANASTASIOS; SREBREVA,LJUBA; FOUNDOULI,ATHINA.
Although several linker histone variants have been studied in both animal and plant organisms, little is known about their distribution during processes that involve alterations in chromatin function, such as differentiation, dedifferentiation and hormone treatment. In this study, we identified linker histone variants by using specific anti-histone Hl antibodies. Each variant's ratio to total Hl in the three developmental zones of maize (Zea mays L.) root and in callus cultures derived from them was estimated in order to define possible alterations either during plant cell differentiation or during their dedifferentiation. We also evaluated linker histone variants' ratios in the developmental zones of maize roots treated with auxin in order to examine the...
