Aridity is a key environmental filter that governs plant community structure by constraining species diversity, distribution, and adaptive capacity, particularly within arid and semi-arid ecosystems. Solanum surattense, a drought-resilient perennial herb, has evolved distinct morphological, anatomical, and physiological adaptations that facilitate its survival under prolonged water stress. Nevertheless, increasing anthropogenic pressure due to its high medicinal and economic value has resulted in overexploitation, leading to significant population declines and habitat fragmentation, thereby threatening its ecological sustainability and long-term persistence.

Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to the rapid development of the social economy. Organic chelating agents such as succinic acid (SA) and oxalic acid (OA) are more efficient, environmentally friendly, and biodegradable compared to inorganic chelating agents and they enhance the solubility, absorption, and stability of metals. To investigate this, we conducted a pot experiment to assess the impact of SA (0.

Seasonal variations directly impact the biochemical and microbial properties of the soil, influence carbon and nutrient cycling within the soil system. Soils under tree plantation (TP) are rich in organic matter and microbial population, making them more susceptible to seasonal variation. We studied the effect of seasonal variations in soil chemical properties (pH, electrical conductivity (EC), total organic carbon (TOC), total nitrogen (TN), C/N ratio etc) and microclimate (moisture and temperature) on microbial respiration (SR), biomass, and carbon (C) utilization efficiency under 13 years old Kadamb ( Miq.

Drought is the worst environmental stress constraint that inflicts heavy losses to global food production, such as wheat. The metabolic responses of seeds produced overtransgenerational exposure to [CO] to recover drought's effects on wheat are still unexplored. Seeds were produced constantly for four generations (F1 to F4) under ambient CO ([CO], 400 μmol L) and elevated CO ([CO], 800 μmol L) concentrations, and then further regrown under natural CO conditions to investigate their effects on the stress memory metabolic processes liable for increasing drought resistance in the next generation (F5).

In the Indo-Gangetic Plains (IGP), rice-wheat cropping system (RWCS) predominates, producing large quantity of crop residue and its management is major concern. Farmers usually burn the residue to clear the field for succeding crop, and burning damages soil microbes, resulted in loss of soil organic matter. Hence, current study was conducted to assess the impact of different Happy seeder based residue management options on changes in microbial dynamics, enzyme activities and soil organic matter content and also to know that alternative method for attaining sustainable wheat productivity in sandy loam soils of Haryana, India.

  • - A study examined how the rhizobacterium Pantoea conspicua affects the growth of sunflower seedlings under arsenate stress, which typically damages the plants by causing oxidative stress and nutrient leakage.
  • - The presence of P. conspicua significantly reduced arsenate levels in the soil (by 75.1%) and enhanced the seedlings' defenses, leading to the production of beneficial compounds like antioxidants and growth hormones.
  • - As a result, sunflower seedlings inoculated with P. conspicua showed improved growth rates (up to 127.7% net assimilation and 113.5% relative growth rate) despite being exposed to arsenate, demonstrating the bacterium's ability to support plant health under stress.
