Title

Arabidopsis MYST6 encodes a rhamnogalacturonan lyase that modulates root growth

Zhou Shao-hua Purdue e-Pubs (Purdue University System) 2010

Other claims from this paper (9)

Observation AtMYST6 was identified as a plant RG-lyase.
Intervention effect Changing MYST6 expression altered total RG-lyase activity and RG-I structure.
Observation Homozygous insertion mutants had short root hairs and reduced root growth.
Observation Homozygous insertion mutants had conditional early shoot senescence.
Observation MYST6 RNAi lines partly reproduced root growth phenotypes but did not senesce early.
Intervention effect Expression of MYST6 under its native promoter rescued mutant phenotypes.
Intervention effect p35S:: MYST6 expression caused partial loss of apical dominance.
Association Expression analysis suggests kinases and phosphatases participate in MYST6 function.
Mechanism MYST6 expression affects RG-I cleavage and may produce lepidimoide, potentially triggering pathways controlling division and organ growth.

Other claims from this paper (11)

Intervention effect Drought inhibited maize growth.
Intervention effect Increasing drought reduced root length, diameter and total biomass.
Intervention effect Increasing drought increased root vigor, root/shoot ratio and root apex polysaccharide content.
Mechanism Root diameter decreased mainly because central cylinder area and vessel diameter decreased.
Intervention effect Root vessel number did not differ significantly among treatments.
Intervention effect Root vessel walls became irregular under water deficit.
Observation Root apex polysaccharide increases occurred mainly in epidermal and pileorhiza cells.
Observation Polysaccharide was mainly dissociated in epidermis cells.
Observation Polysaccharide was mainly starch grains in pileorhiza cells.
Mechanism Root adjustments under water deficit were interpreted as enhancing water absorption and drought resistance.
Intervention effect Severe drought inhibited or damaged root hair growth.
