EFFECT OF CHROMIUM ON GROWTH AND YIELD OF Vigna mungo (L.)

This study was conducted to find out the effect of different concentrations (control 5, 10, 25, 50, 100 and 200 mg/l) of chromium on growth, yield of black gram (Vigna mungo L.). Pot culture experiments were carried out with black gram seeds with different concentrations of chromium solution. The morphological growth parameters were recorded at 15, 30, 45 and 60 days old chromium treated plants. The yield was recorded at the time of harvest. The study revealed that, the increase in chromium reduce the growth and and yield in black gram plants

Occurrence of Oratosquilla oratoria (De Haan, 1844) and Oratosquillina gravieri (Manning, 1978) from the trawl bycatches of Nagapattinam region, Tamil Nadu

Six species of mantis shrimps were recorded in the trawl catches of Nagapattinam region during January – December, 2018. The occurrence of two species namely Oratosquilla oratoria (De Haan, 1844) and Oratosquillina gravieri (Manning, 1978) were reported for the first time in the trawl bycatches of Nagapattinam region. The morphometrics of these two species is reported in this paper. Presence of inferodistal spine in the merus of the raptorial claw, rostral plate short and trapezoid to square in shape, 5th abdominal segment without submedian patch, 4th abdominal segment submedian carinae unarmed in Oratosquilla oratoria and rostral plate elongate and rectangle, lateral process of 6th thoracic somite with slender, triangular anterior lobe and dactylus of the raptorial claw with 6 teeth in Oratosquillina gravieri are chief characters to differentiate from other species

A non-canonical scaffold-type E3 ligase complex mediates protein UFMylation

Protein UFMylation, i.e., post‐translational modification with ubiquitin‐fold modifier 1 (UFM1), is essential for cellular and endoplasmic reticulum homeostasis. Despite its biological importance, we have a poor understanding of how UFM1 is conjugated onto substrates. Here, we use a rebuilding approach to define the minimal requirements of protein UFMylation. We find that the reported cognate E3 ligase UFL1 is inactive on its own and instead requires the adaptor protein UFBP1 to form an active E3 ligase complex. Structure predictions suggest the UFL1/UFBP1 complex to be made up of winged helix (WH) domain repeats. We show that UFL1/UFBP1 utilizes a scaffold‐type E3 ligase mechanism that activates the UFM1‐conjugating E2 enzyme, UFC1, for aminolysis. Further, we characterize a second adaptor protein CDK5RAP3 that binds to and forms an integral part of the ligase complex. Unexpectedly, we find that CDK5RAP3 inhibits UFL1/UFBP1 ligase activity in vitro. Results from reconstituting ribosome UFMylation suggest that CDK5RAP3 functions as a substrate adaptor that directs UFMylation to the ribosomal protein RPL26. In summary, our reconstitution approach reveals the biochemical basis of UFMylation and regulatory principles of this atypical E3 ligase complex

The histone chaperone Vps75 forms multiple oligomeric assemblies capable of mediating exchange between histone H3–H4 tetramers and Asf1–H3–H4 complexes

Wellcome Trust [094090, 097945, 099149]; Medical Research Council [G1100021]. Funding for open access charge: Wellcome Trust.Vps75 is a histone chaperone that has been historically characterized as homodimer by X-ray crystallography. In this study, we present a crystal structure containing two related tetrameric forms of Vps75 within the crystal lattice. We show Vps75 associates with histones in multiple oligomers. In the presence of equimolar H3-H4 and Vps75, the major species is a reconfigured Vps75 tetramer bound to a histone H3-H4 tetramer. However, in the presence of excess histones, a Vps75 dimer bound to a histone H3-H4 tetramer predominates. We show the Vps75-H3-H4 interaction is compatible with the histone chaperone Asf1 and deduce a structural model of the Vps75-Asf1-H3-H4 (VAH) co-chaperone complex using the Pulsed Electron-electron Double Resonance (PELDOR) technique and cross-linking MS/MS distance restraints. The model provides a molecular basis for the involvement of both Vps75 and Asf1 in Rtt109 catalysed histone H3 K9 acetylation. In the absence of Asf1 this model can be used to generate a complex consisting of a reconfigured Vps75 tetramer bound to a H3-H4 tetramer. This provides a structural explanation for many of the complexes detected biochemically and illustrates the ability of Vps75 to interact with dimeric or tetrameric H3-H4 using the same interaction surface.Publisher PDFPeer reviewe
