Mineral nutrient acquisition under stress: Sensing, signaling, and transportation.

Plants commonly face abiotic stressors like drought, salinity, and limited nutrient availability which disrupt the homeostatic networks of mineral acquisition and hamper productivity. In this review we aim to clarify the molecular platforms by which plants sense and act in response to fluctuating availability of nitrogen and phosphorus under stress. Our data show that the dual-affinity nitrate transporter NRT1.

Management of Phytophthora parasitica causing gummosis in citrus using biogenic copper oxide nanoparticles.

Aim: The main aim of the present study was to develop nanotechnology-based solutions for the management of a fungus, Phytophthora parasitica causing gummosis in citrus.

Methods And Results: Biogenic copper nanoparticles (CuONPs) were synthesized using two different biocontrol agents, Pseudomonas fluorescens and Trichoderma viride and characterized using different analytical techniques. Furthermore, in vitro (at the concentrations of 10, 15, 30, 50, 70, 100 and 150 mg/L) and in vivo (at the concentration of 100 mg/L) activities of these nanoparticles were evaluated for their antifungal efficacy against P.

Transcriptomic signature reveals mechanism of flower bud distortion in witches'-broom disease of soybean (Glycine max).

Background: Soybean (Glycine max L. Merril) crop is major source of edible oil and protein for human and animals besides its various industrial uses including biofuels. Phytoplasma induced floral bud distortion syndrome (FBD), also known as witches' broom syndrome (WBS) has been one of the major biotic stresses adversely affecting its productivity.

Cytological behaviour of floral organs and in silico characterization of differentially expressed transcript-derived fragments associated with 'floral bud distortion' in soybean.

An attempt was made to understand the 'floral bud distortion' (FBD), an unexplored disorder prevailing in soybean. Cytological behaviour of floral reproductive organs and in silico characterization of differentially expressed transcript-derived fragments (TDFs) in symptomatic and asymptomatic soybean plants were carried out. Pollens in asymptomatic plants do not have defects in number, size, shape and function.

Parameters influencing Agrobacterium-mediated transformation system in safflower genotypes AKS-207 and PKV Pink.

Shoot regeneration in safflower (Carthamus tinctorius 'AKS 207' and 'PKV Pink') genetically transformed using Agrobacterium was used for assessing various constraints to the efficiency of transformation including infection period, virulence induction medium, co-cultivation period, bacterial titre, selection regime, and the natural phenolic compound acetosyringone. Transformation frequency was promising with 8-10-day-old cotyledonary leaf explants. Therefore, explants of that age cultured on Agrobacterium minimal medium (AB) containing 100 µM acetosyringone were infected with Agrobacterium (cell titre 0.
