Gene Symbol

• Os04g0433800 <=> OsRecQl4,RecQl4,OsMed34_1,Med34_1

Function

• OsRecQl4 plays an important role as a caretaker, maintaining genome stability during DNA replication stress in the rice meristem.

Phenotypic analysis

• Osrecql4 mutant plants showed hypersensitivity to DNA damaging agents and enhanced frequency of HR compared to wild-type (WT) plants.

Expression

• Expression of OsRecQl4 was analyzed by northern blot in 7-day-old seedlings of the japonica-type rice cultivars Dongjin or Nipponbare. Using probe A (Figure 1A), relatively strong signals were observed in the basal parts of shoots (BS, as defined in Figure 1B) including the shoot apical meristem (SAM), and weak signals were observed in the root (R). No signal was detected in the lower (LS) or upper (US) shoot (Figure 1B).
• OsRecQl4 was highly expressed in the RAM expression of OsRecQl4 was restricted to meristematic tissues.
