Chapter
Changes in the environment and demography have been a defining factor throughout humans’ evolutionary history, reflected by noticeable changes in dietary habits. It can be seen in the shift from foraging-based eating and cooking to the domestication of animals and plants. Such environmental and dietary transitions led selective pressures are believ...
Chapter
Plants face a wide range of environmental challenges during their developmental stages, which affect many physiological and biochemical processes, and ultimately their growth, thereby leading to reduced yield. Tropospheric ozone (O3) is considered to be the most severe air pollutant, severely affecting the growth, yield, and produce quality in seve...
Chapter
Hydrogen Sulfide in Plant Biology: Past and Present includes 17 chapters, with topics from cross-talk and lateral root development under stress, to post-translational modifications and disease resistance. With emerging research on the different roles and applications of H2S, this title compiles the latest advances of this key signaling molecule. Th...

Guard cells regulate plant gas exchange by controlling the aperture of stomatal pores. Stomatal closure involves a multi-input signaling network that governs the activity of ion channels, which in turn regulate guard cell turgor pressure and volume. We describe a forward genetic screen to identify novel components involved in stomatal movements. Th...

The present study was conducted to assess the impact of elevated levels of O3 and shifting of crop calendar practice, singly, and in combination on Triticum aestivum cv. HD 2967 on its growth, gas exchange parameters, and yield attributes in open-top chambers (OTCs). Two sowing dates were considered: timely sown and late sown. Late sowing was delay...

Eleven local cultivars of wheat (Triticum aestivum) were chosen to study the effect of ambient ozone (O3) concentration in the Indo-Gangetic Plains (IGP) of India at two high-ozone experimental sites by using 300 ppm of Ethylenediurea (EDU) as a chemical protectant against O3. The O3 level was more than double the critical threshold reported for wh...

To explore molecular mechanisms underlying the physiological response of Selaginella bryopteris, a comprehensive proteome analysis was carried out in roots and fronds undergoing dehydration and rehydration. Plants were dehydrated for 7 days followed by 2 h and 24 h of rehydration. In roots out of 59 identified spots, 58 protein spots were found to...

Percent volume values of protein spots in root and fronds of S. bryopteris.
Data
Replicate gel images of root and fronds during dehydration and rehydrations (RI and RII).
Data
Detailed information of Mascot identified proteins.
Data
PCA analysis of root and frond proteins.
Data
Figure of all protein spots differentially expressed during DE and RI and RII.

Under the climate change scenario, protected cultivation may possibly provide ample scope for ‘off'season production of high-value vegetable crops. Among the highvalue crops, tomato (Solanum lycopersicum Mill.) is most important and rich sources of lycopene, β-carotene, phenols, flavonoids and many vitamins. The performances of eight tomato varieti...

An inexpensive source of industrially useful enzymes is critical for their commercial production. We have produced an industrially valuable recombinant superoxide dismutase (SOD) in tobacco chloroplasts. A gene from Withania somnifera, encoding a highly stable Cu/Zn SOD, was cloned into a chloroplast transformation vector. It expressed the SOD in t...

A study was conducted to investigate the influence of sodicity induced changes in soil physical properties on paddy root growth in the normal agriculture, semi-reclaimed and sodic soils. The root growth (length, length density, biomass and distribution pattern) were unfavourably affected by the soil physical properties (bulk density, soil aggregate...

Increasing anthropogenic and biogenic emissions of precursor compounds have led to high tropospheric ozone concentrations in India particularly in Indo-Gangetic Plains, which is the most fertile and cultivated area of this rapidly developing country. Current ozone risk models, based on European and North American data, provide inaccurate estimation...

Cotton genotype RAHS 187 was analyzed for changes in physiology, biochemistry and proteome due to drought stress. The deleterious effect of drought in cotton plants was mainly targeted towards photosynthesis. The gas-exchange parameters of net photosynthesis (A), stomatal conductance (g(s)) and transpiration (E) showed a decreasing trend as the dro...

The changes in photosynthetic pigments, chlorophyll fluorescence, protein content, and antioxidant enzymes were investigated in a foliose lichen Pyxine cocoes, which was subjected to increasing concentrations of arsenate. The arsenate concentrations of 10, 25, 50, 75, 100, and 200 μM were sprayed every alternate day on the lichen thallus. The thall...

The sporophyte and gametophyte of Pteris vittata are arsenic hyperaccumulators, however, little is known about the mechanism by which the gametophyte deals with this toxic element. An in vitro system (spores grown in arsenic amended nutrient media) was used to investigate the impact of arsenic on growth of the gametophyte and the role of antioxidat...

Selaginella bryopteris is a lycophyte resurrection plant, which incurves during desiccation and recovers on availability of moisture. The aim of the study was to test and understand the various physiological and biochemical changes the fronds undergo during desiccation and rehydration, to get an insight as to how this plant adapts and survives thro...
