A plant growth promoting rhizobacterium and temperature effects on performance of 18 clones of potato |
|
Answer» A survey of GENOTYPIC responses to beneficial bacterium (Pseudomonas sp. strain PsJN) was conductedin VITRO andex vitro, under two temperature conditions, using eighteen clones of potato of different heat stress tolerance: temperate adapted cultivars Kennebec and Russet Burbank; heat tolerant DTO-2, DTO-28, DTO-33, LT-1, LT-2, LT-5, LT-6, LT-7, LT-8, LT-9, Y84-02, NDD277-2, Désirée, and Maine-47; and heat sensitive abscissic acid (ABA)-deficient mutants 11401-01 and 9120-05. Nodal explants taken from 6-week-old bacterized and non-bacterized control plantlets were culturedin vitro on a hormone-free potato nodal cutting medium, and placed at either 20/15 C or 33/25 C day/night temperature, 12h photoperiod and 250 µE m−2 s−1 mixture of fluorescent and incandescent light, for six weeks. The tuberization response was studiedex vitro after two weeks acclimation of 2-week old plantlets at 33/25C. The acclimated plantlets were transplanted to 3L plastic nursery pots containing peat-based Pro-Mix growing medium and placed in growth chambers at either 20/15 or 33/25 C day/night temperature, 12 h photoperiod, 475 μE m−2 s−1 light and ≈80% RH, for 12 weeks. Compared to the non-bacterized controls, BACTERIZATION significantly increased stem length of 12, shoot biomass of 9, and root biomass of 2 clones at 20/15C; and stem length of 14, shoot biomass of 15, and root biomass of 13 clones at 33/25C. High temperature increased length of internodes and had either no EFFECT or slightly decreased node number. Temperature increase had the most dramatic effect on root development. An average shoot to root ratio decreased from 3.7 at 20/15 C to 1.7 at 33/25 C for non-bacterized plantlets and, respectively, from 4.3 to 1.5 for bacterized. The beneficial effect of bacterization on root biomass was the most pronounced in LT-1 and Maine-47 at 20/15 C and LT-8, Maine 47, DTO-2, Kennebec, NDD277-2 and 11401-01 at 33/25C. The temperature elevation did not significantly affect root biomass of LT-6, DTO-28 and Désirée. Temperature stress caused severe reduction in tuber number and tuber fresh weight. ABA-deficient mutants did not produce any tubers and LT-8, LT-9, Y84-027 and DTO-28 tuberized very poorly at 33/25C. DTO-33, Désirée, LT-1 and Kennebec gave the highest number of tubers per pot and Kennebec, LT-1, Désirée and LT-7 the highest yields at this temperature. There was no significant effect of bacterization on tuberization at 20/15 C but at 33/25 C bacterization significantly enhanced tuber number and weight in LT-7 and reduced tuber weight in DTO-2. Although there was no clear link between thein vitro response of particular clones to bacterization and their heat stress tolerance, improvement ofex vitro performance of heat tolerant LT-7 indicates that RHIZOSPHERE bacteria may play a role in clonal adaptation of potato to heat stress. |

How to learn answers very quickly and and making them understand |
|
Answer» Learning is the act of making ourselves remember something, may it be a piece of text or something else. The below tips will surely help you to learn something EASIER and faster : 1. Watch video lessons on that particular topic. It is truly believed that we remember the things we see more longer than the things we read. That is why, you remember entire movie but not even one PAGE of history ^_^ 2. Use educational platforms like Brainly, which facilitates the learning of students on wider aspect. You can have knowledge on various topics which will also include the things of your syllabus. 3. Study at night as the quite environment of the night improves the capacity of our brain to learn things. Moreover, our brain is void of all distractions leading to an increase in the concentration on things we learn. 4. Study before sleep as it is scientifically proved that the things we do and read before sleeping are naturally recalled by our brain at night. This HELPS our brain to learn things properly and for long time. 5. Do not just keep READING books like bookworms. It is unhealthy for you. Rather study by taking BREAKS. |

Stereoelectronic and steric effects in side chains preorganize a protein main chain |
|
Answer» Preorganization is shown to endow a protein with extraordinary conformational stability. This preorganization is achieved by installing side-chain substituents that impose stereoelectronic and steric effects that restrict main-chain torsion angles. Replacing proline residues in (ProProGly)(7) collagen strands with 4-fluoroproline and 4-methylproline leads to the most stable known triple helices, having T ( m ) values that are increased by > 50 degrees C. Differential scanning calorimetry data indicate an entropic basis to the hyperstability, as expected from an origin in preorganization. Structural data at a resolution of 1.21 A reveal a prototypical triple HELIX with insignificant deviations to its main chain, even though 2/3 of the residues are nonnatural. Thus, preorganization of a main chain by subtle CHANGES to side CHAINS can CONFER extraordinary conformational stability upon a protein without perturbing its structure. |
