Plant Developmental Biology - Biotechnological Perspectives

Manyexcitingdiscoveriesinrecentdecadeshavecontributednewknowledgeto ourunderstandingofthemechanismsthatregulatevariousstagesofplantgrowth anddevelopment. Suchinformation,coupledwithadvancesincellandmolecular biology,isfundamentaltocropimprovementusingbiotechnologicalapproaches. Twovolumesconstitutethepresentwork. The?rst,comprising22chapters, commenceswithintroductionsrelatingtogeneregulatorymodelsforplantdev- opmentandcropimprovement,particularlytheuseofArabidopsisasamodelplant. Thesechaptersarefollowedbyspeci?ctopicsthatfocusondifferentdevelopmental aspectsassociatedwithvegetativeandreproductivephasesofthelifecycleofa plant. Six chapters discuss vegetative growth and development. Their contents considertopicssuchasshootbranching,buddormancyandgrowth,thedevel- ment of roots, nodules and tubers, and senescence.
