Qhov txawv ntawm abscisic acid thiab gibberellins yog abscisic acid yog isoprenoid cog hormone whereas gibberellin yog diterpenoid cog hormone.
Cov tshuaj hormones cog yog qhov taw qhia cov molecules hauv cov nroj tsuag uas tuaj yeem tswj cov nroj tsuag kev loj hlob thiab kev loj hlob. Txawm li cas los xij, cov molecules no tshwm sim hauv qhov tsis tshua muaj siab. Abscisic acid thiab gibberellin yog ob hom tshuaj hormones cog.
Abscisic Acid yog dab tsi?
Abscisic acid yog ib qho tseem ceeb ntawm cov tshuaj hormones uas tswj cov noob thiab cov noob dormancy thiab tswj lub cev loj thiab kaw lub plab. Ntxiv mus, cov tshuaj no tseem ceeb hauv kev teb rau ib puag ncig kev ntxhov siab, e.g. drought, salinity, txias tolerance, freezing kam rau ua, kub siab, hnyav hlau ion kam rau ua, thiab lwm yam.
Daim duab 01: Cov qauv tshuaj ntawm Abscisic Acid
Abscisic acid yog cov organic compound uas muaj cov tshuaj formula C15H20O4 Cov molar mass ntawm no compound yog 264.32 g / mol. Thaum muab rho tawm los ntawm cov nroj tsuag, qhov sib xyaw no zoo li cov xim tsis muaj kob nrog qhov ntom ntom uas siab dua me ntsis ntawm qhov ntom ntawm dej.
Hauv kev faib tawm, peb tuaj yeem faib cov abscisic acid ua ib qho isoprenoid molecule. Nyob rau hauv nws txoj kev bio-synthesis feem ntau, abscisic acid yog tsim los ntawm xanthoxin, nyob rau hauv lub xub ntiag ntawm xanthoxin dehydrogenase enzyme. Tsis tas li ntawd, cov tshuaj hormones no tuaj yeem ua rau tsis muaj zog los ntawm cov tshuaj tiv thaiv kab mob ntshav qab zib. Peb tuaj yeem sau cov teebmeem ntawm cov tshuaj no rau cov nroj tsuag.
- Zoo kawg kaw
- Txhob ua pa tawm kom tsis txhob poob dej
- Inhibits fruit ripening
- Ntev kev faib cell
- Regulates noob dormancy
- Inhibits lub synthesis ntawm kinetin nucleotide
- Downregulates enzymes xav tau rau photosynthesis
YGibberellins yog dab tsi?
Gibberellins yog cov tshuaj hormones cog uas tuaj yeem tswj kev txhim kho ntawm cov nroj tsuag, suav nrog cov txheej txheem elongation, txheej txheem germination, flowering, dormancy, thiab lwm yam. Hauv nws qhov kev faib tawm, peb tuaj yeem faib cov gibberellins li diterpenoid acids. Qhov no yog vim cov nroj tsuag cov tshuaj hormones tsim los ntawm txoj kev terpenoid uas tshwm sim hauv plastids thiab hloov kho hauv endoplasmic reticulum thiab cytosol.
Daim duab 02: Cov qauv tshuaj ntawm Gibberellic Acid, ib daim ntawv ntawm 19-Carbon Gibberellin
Thaum xav txog cov qauv tshuaj ntawm gibberellins, lawv yog tetracyclic diterpene acids. Muaj ob chav kawm loj ntawm gibberellins nyob ntawm seb muaj pes tsawg carbon atoms nyob rau hauv cov molecules. Lawv yog 19-carbon gibberellins thiab 20-carbon gibberellins. Feem ntau, 19-carbon gibberellins yog cov khoom siv roj ntsha. Ib qho piv txwv zoo rau cov pab pawg no ntawm gibberellins yog gibberellic acid. Cov txiaj ntsig ntawm cov tshuaj hormones cog rau ntawm cov nroj tsuag kev loj hlob thiab kev loj hlob muaj xws li hauv qab no:
- Txhob dormancy thiab lwm yam ntawm germination
- Signalling starch hydrolysis hauv noob
- Tsov txias txias
- Txhawb nqa cell elongation, tawg, thiab budding
Qhov txawv ntawm Abscisic Acid thiab Gibberellins yog dab tsi?
Cov tshuaj hormones cog yog lub luag haujlwm rau kev tswj cov nroj tsuag kev loj hlob thiab kev loj hlob. Abscisic acid yog ib qho tseem ceeb ntawm cov tshuaj hormones uas pab nyob rau hauv ntau txoj kev loj hlob, nrog rau kev tswj ntawm lub cev loj thiab lub plab kaw, thiab noob thiab noob dormancy. Gibberellins yog cov tshuaj hormones uas tuaj yeem tswj cov kev loj hlob ntawm cov nroj tsuag, suav nrog cov txheej txheem elongation, germination, flowering, dormancy, thiab lwm yam..
Hauv qab infographic muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm abscisic acid thiab gibberellins.
Summary – Abscisic Acid vs Gibberellins
Cov tshuaj hormones cog yog lub luag haujlwm rau kev tswj cov nroj tsuag kev loj hlob thiab kev loj hlob. Abscisic acid thiab gibberellin yog ob hom tshuaj hormones cog. Qhov sib txawv tseem ceeb ntawm abscisic acid thiab gibberellins yog abscisic acid yog ib qho isoprenoid cog hormone whereas gibberellin yog diterpenoid cog hormone.
