Studies that investigated the genetic basis of source and sink related traits have been widely conducted.However,the vascular system that links source and sink received much less attention.When maize was domesticated from its wild ancestor,teosinte,the external morphology has changed dramatically,however,less is known for the inteeral anatomy changes.In this study,using a large maize-teosinte experimental population,we performed a high-resolution quantitative trait locus (QTL)mapping for the number of vascular bundle in the uppermost intemode of maize stem.

中国樱桃(Prunus pseudocerasus Lindl.)、欧洲甜樱桃(P.avium Linn.)和毛樱桃(P.tomentosa Thunb.)是重要的樱桃栽培种，在长期的驯化过程中形成许多地方种质和栽培品种.然而对于樱桃主要栽培种内的遗传多样性及种间遗传关系仍缺乏研究.从DNA序列变异角度深入分析其遗传多样性及种间遗传关系，对于正确保护和开发利用优异樱桃资源具有重要意义.
辣椒有较强的抗旱能力，耐水涝能力较差。水涝胁迫会限制辣椒的正常生长，制约辣椒的生产。筛选抗水涝能力较强的种质是提高辣椒产量和质量，促进辣椒开发与利用的重要基础。
